Executive summary
Entura is pleased to submit this proposal to American Samoa Power Authority (ASPA) in response to a Request for Proposal (RFP) released on 17 June 2013.
Entura is offering its technical services to ASPA for the ‘Renewable Energy Integration Study’ for the ASPA power grid.
Entura has considerable experience with renewable energy systems studies dating back to 1998 when the King Island Renewable Energy project connected 3 Nordex 225 kW turbines to the distribution system on the island. Since that time Entura has successfully undertaken many connections in Australia and overseas including China, India and Pacific Islands.
We are ideal for this assignment for the following reasons: Entura is the consulting arm of Hydro Tasmania, Australia’s largest renewable energy producer and the utility responsible for providing electricity to the remote communities of King, Flinders and Cape Barren Islands in the middle of Bass Strait. We therefore understand the unique but broad issues relating to working in isolated communities; not just the grid connection issues relating to producing reliable, continuous supply but also the logistical problem of installing a solution. Entura has hands on experience in integrating wind turbines, solar PV arrays, wind/diesel, solar/diesel and wind/solar/diesel systems having delivered similar systems on King, Flinders, Cape Barren, Maria, Bruny and Maatsuyker Islands. Entura has experience in integrating these systems with existing local distribution network infrastructure and associated risks and grid connection issues. Entura has experience with a wide range of storage technologies, having investigated many technologies and deployed several on King Island. The technologies we have deployed include Vanadium Redox Batteries (VRBs), carbon block, small battery systems and pumped storage. We also are familiar with a wide range of other technologies such as kinetic energy storage and recovery systems. Entura has experience delivering similar projects into some of the world’s most remote and harsh environments. We have undertaken master‐plans for deployment of 100% renewable systems to Norfolk Island. Our staff have also been seconded into the Australian Antarctic Division to integrate wind turbines with existing diesel systems at Australia’s Antarctic bases.
Entura understands that ASPA is looking to make a decision on its involvement by 1 August 2013. Entura will commit to delivering the scope of work detailed by the RFP and this proposal, for a total fee of USD80 000.
Entura’s proposed team of experienced consultants is set out in Section 1.3 with individual CVs provided in Appendix B.

3. Our approach
Entura proposes to undertake the proposed assessment through the following task breakdown.
3.1 Outline of project tasks
Task 0 Base case development Task 1 Production cost modelling Task 2 Steady State Analysis Task 3 Dynamic modelling/stability analysis Task 4 Short Circuit Analysis Task 5 Individual Feeder Analysis
3.1.1 Task 0 – Base case development
Purpose: To develop and validate baseline (year 2013) steady state and dynamic model of ASPA’s network To develop and validate baseline (year 2013) energy resource model To perform and validate baseline production cost modelling.
Methodology: Collate all the available information on ASPA’s network including unique characteristics of the system to produce a system model that accurately represents the physical system. We are proposing to use PSS/E modelling software to build steady state and dynamic system model. Validate and retune this model using available system performance data. Similarly, to accurately perform production cost modelling, we have proposed to collate all available solar irradiation and power output time series data from existing 2.4 MWAC PV plant and integrate mesoscale/satellite data to produce baseline (year 2013) energy resource model using PVsyst software. Validate and retune this energy model using available system performance data. This will in turn be used to project baseline production costs. Both production cost and dynamic simulations will be validated against available system performance data. We will re‐tune energy resource and PSS/E model to match system performance data to build confidence in study scenarios. Maximum of one iteration is proposed for re‐tuning the model or else make moderately conservative assumptions.
Output: Working steady state PSS/E model of ASPA’s network. Working dynamic PSS/E model of each existing diesel generator, PV units, load dynamics, under‐frequency load shedding (UFLS) schemes and automatic generation control (AGC) using PSS/E software and available system performance data.
19 Renewable Energy Integration Study for ASPA power grid ‐ Entura submission Revision No: 0 E303587 18 July 2013
3.1.2 Task 1 – Production cost modelling
Purpose: To review the available wind and solar data for American Samoa and prepare the data for further analysis To estimate the unconstrained annual energy and a time series of generation for each of the ASPA renewable production scenarios outlined in the RFP Report on cost of production modelled under each scenario, as well as other factors such as emissions, spinning reserve forecasts and changes in O&M costs.
Methodology: Review wind data supplied from sites in American Samoa, quality check, and create record Obtain local weather station and mesoscale/satellite data (3TIER and NASA SSE) in order to provide an indication of the long term variability of wind and solar resource Compare and correlate the wind speed data to create a time series wind speed data set at likely wind turbine hub height which can be used in the energy generation modelling Compare and correlate the solar radiation data with production data from solar installations to create a representative time series data set which can be used in the energy generation modelling Prediction of unconstrained energy generation for indicative wind turbine generators at location of wind plant (specified by ASPA), using WAsP software in conjunction with Entura’s wind analysis procedures Prediction of PV plant output at locations specified by ASPA using PVsyst software Collate indicative costs for plant, operations & maintenance and fuel Model the operation of the five future renewable generation scenarios with the representative time series resource data and loads and test the system’s ability to meet demand and any requirement for energy storage Compare capital and operating costs estimated by varying the mix between solar and wind to obtain the overall renewable percentage, and identify the lowest cost installation Comment on likely production costs changes in the case of accurate resource forecasting.
Output: Hourly generation/dispatch data (wind, solar, storage and diesel generator) for each scenario for a single representative year Summary of cost of energy, fuel and emissions reductions, requirement for spinning reserve/storage, O&M costs and reliability of design under each scenario.
20 Renewable Energy Integration Study for ASPA power grid ‐ Entura submission Revision No: 0 E303587 18 July 2013
3.1.3 Task 2 – Steady state analysis
Purpose: To develop PSS/E load flow models for five scenarios at both high and low load system conditions To identify voltage and thermal issues and mitigation for each penetration scenario.
Methodology: Use the validated baseline load flow case from Task 0 and location information for wind and solar capacity to be proposed by ASPA to develop PSS/E models for each penetration scenario. Use these cases to investigate steady state voltage rise/drop and fluctuations at the connection point and at key points on the network and thermal line loading impacts with changing renewable penetration levels at both high and low load system conditions. Identify key issues for each case. Some of the overloading issues identified can be relieved by certain dispatch actions like splitting busbars, changing lower voltage network topology in order to redistribute load‐ demand or change of generation units engagement etc. Investigate such opportunities or else propose and simulate mitigation measures and identify cost implications and resulting renewable penetration levels.
Output: Working PSS/E load flow models for five penetration scenarios at both high and low load system conditions Identify key risks and issues and propose mitigation measures and cost implications.
3.1.4 Task 3 ‐ Dynamic modelling/stability analysis
Purpose: To propose any mitigation measures required so as with increased renewable energy penetration, the operating conditions are always within adequate limits, both during the contingency and after clearing the fault.
Methodology: Use the validated baseline PSS/E dynamic model from Task 0 and location information for wind and solar capacity to be proposed by ASPA to develop PSS/E models for each penetration scenario for both high and low load system conditions. Identify worst‐case generation scenarios in terms of system performance based on the generation profiles developed from the production cost modelling and energy modelling from Task 0 and 1. The system conditions will be chosen based on inertia, fault level, synchronous generation distribution and penetration level. Use dynamic simulation to illustrate system performance under disturbances for these system conditions. In ASPA’s power grid with increased renewable energy penetration limits, there are some operation conditions in which transient stability is severely at risk. The critical operating scenario takes place when the highest renewable generation coincides with the lowest
21 Renewable Energy Integration Study for ASPA power grid ‐ Entura submission Revision No: 0 E303587 18 July 2013
demand in the system because there are less diesel units connected. In this operating situation, the two disturbances that will be studied are:
o Three‐phase fault on a feeder which doesn’t isolate the two power stations
o Three‐phase fault on the tie line between Tafuna and Satala power plants. Use dynamic simulations for selected system conditions and for the largest ASPA contingency event (loss of largest generator) for all study scenarios and verify the system’s ability to provide adequate frequency response and restore its nominal frequency without load shedding or tripping of diesel generators due to under/over speed protection. Use dynamic simulations of the highest wind and solar power ramps to verify system’s ability to provide stable operation during such weather driven ramping events. Identify mitigation measures for high penetration scenarios (such as additional spinning reserves, wind providing inertia/frequency response, voltage control or energy storage) in case the system is not stable under the above conditions and use simulations to show improved system performance. Use transient simulation under self‐recovering voltage faults for all penetration levels and load conditions to verify the system’s ability to maintain satisfactory operation (low voltage ride‐ through capability). Propose and simulate mitigation measures in case of unsatisfactory transient performance for certain scenarios and load conditions. Evaluate the need for ancillary services and if deemed necessary, include in production cost modelling.
Output: Working PSS/E load flow models for five penetration scenarios at both high and low load system conditions. Identify key risks and issues and propose mitigation measures and cost implications.
3.1.5 Task 4 ‐ Short circuit analysis
Purpose: To identify any limitations in terms of existing switchgear capability to accommodate additional fault level from the proposed generation.
Methodology: Utilise re‐tuned (if necessary) renewable energy penetration scenarios from Task 1 & 3 to estimate the fault contribution at the point of connection of proposed wind and solar plant and at key locations of the ASPA’s network. The short circuit analysis will be using PSS/E and will include three‐phase, single and double line‐to‐ground faults.
Output: Identify limitations in existing switchgear capability.
22 Renewable Energy Integration Study for ASPA power grid ‐ Entura submission Revision No: 0 E303587 18 July 2013
3.1.6 Task 5 ‐ Individual feeder analysis
Methodology: Use the validated baseline PSS/E case from Task 0. Perform load flow analysis to determine existing limits for generation penetration for individual feeders. This stepped multi‐sited P/Q injection exercise will take into consideration current feeder and substation limits. Provide ASPA the limits of renewable energy penetration for individual feeder without any augmentation. Identify ‘easy’ upgrades that could be made to increase these penetration limits.
Output: Determine maximum renewable energy penetration level for individual ASPA feeders Propose mitigation options to increase penetration limits.

www.entura.com.au [email protected] Project overview OctoberKING 2012 ISLAND RENEWABLE ENERGY INTEGRATION PROJECT (KIREIP) Welcome to King Island
Hydro Tasmania is pleased to showcase the world- leading renewable energy projects that have been undertaken on King Island over the past 15 years and our plans for further development. King Island is one of several inhabited islands located in Bass Strait, the body of water separating the north coast of Tasmania and the south coast of Victoria on mainland Australia.
King Island is famous for its premium products such as beef and dairy, as well as kelp farming and tourism. The residents of King Island form a tightly-knit and self-reliant community – finding ways to overcome the challenges of living on a remote island.
Generation of electricity on this remote island is the same – it must be self-reliant.
Hydro Tasmania is responsible for the generation, distribution and retail of electricity on King Island. Like thousands of other islands across the globe, King Island has historically relied purely on diesel generators for electricity supply, a reliable but costly and emissions-intensive source of power.
Since 1985 Hydro Tasmania has been improving the power system on King Island and aspiring to reduce the dependence on imported diesel fuel through deploying a range of innovative technologies. Read on to find out about what we have achieved to date and our world-leading plans for the future.
King Island King Island Power Station Historically power on King Island was regionally focused on the main towns on the island. Privately-owned power stations existed in the two major towns.
In 1986 that all changed when the King Island Power Station was officially opened and a The old Currie Power Station power system for the whole of King Island was established with a distribution network spanning most of the island.
The original King Island Power Station
By taking on the responsibility for the power system, Hydro Tasmania could increase the reliability of power supply and provide power to both commercial and residential customers.
The station was originally fitted with 2 x 1200 kW Diesel machines and 1 x 800 kW machine giving a firm capacity of 2000 kW. Space to accommodate a fourth unit was included in the original construction – a good piece of forward thinking.
As load has grown over time a fourth 1200 kW machine was added to this space, RENEWABLE ENERGY and all three 1200 kW units have since been upgraded to 1600 kW machines. The new diesel units are more efficient and themselves contribute to reducing diesel consumption. Diesel In 2012 the station’s installed diesel capacity was 6000 kW with a firm capacity of 4400 kW.
The King Island Power Station has been designed for automatic operation and is only staffed during business hours. Essential maintenance and daytime 0% supervised operation of the station is carried out by our skilled operators. 1 Huxley Hill Wind Farm
Nordex wind turbine nose cone and blades being moved into place
Hydro Tasmania is a pioneer of renewable energy.We’ve had nearly 100 years experience in generating power from clean, renewable sources.
Our next natural step on King Island was to ensure that renewable energy was part of the mix.
King Island has the advantage of being located in the path of a world-class wind resource - the roaring forties.
In 1998 Hydro Tasmania commissioned three Nordex N29 wind turbine generators at Huxley Hill near the King Island Power Station and in doing so established Australia’s second commercial wind farm.
The three turbines are rated at 250 kW each, providing a total renewable energy capacity of 750 kW.
RENEWABLE ENERGY
Diesel Wind
15% The tower base and nacelle 2 This new renewable source of energy showed dividends right away, by reducing diesel use. This in turn reduced carbon emissions and the cost of supplying the island with electricity.
When the Nordex machines were the sole renewable generation on the island they contributed on average around 15 per cent of the island’s energy needs. This resulted in a 15 per cent reduction in annual diesel fuel use or approximately 590 000 litre reduction in diesel use per annum.
The Huxley Hill Wind Farm was a huge success, paving the way for more renewable energy development on the island. It was also the first wind farm in Australia to earn Renewable Energy Certificates, one of many ‘firsts’ for King Island.

The larger Vestas wind turbine
The next step in King Island’s renewable energy journey started in the year 2000 and was officially opened in 2004.
The goal of KIREX was to increase the contribution of renewable energy in the system, through expanding the Huxley Hill Wind Farm, and implementing a new control system and an emerging battery technology to store energy.
Two larger wind turbines were constructed to expand the wind farm. For those who are technically minded, the turbines were Vestas V52s which are capable of producing a maximum of 850 kW of power each, increasing the total rated capacity of the wind farm to 2.45 MW.

Diesel Wind
Liquid Control Battery Upgrade 30% Tower component being transported to site 4 The extended Huxley Hill Wind Farm
These newer turbines also allow our operators to vary the power output for the same quantity of wind, making them a bit easier to add to the power system.
The KIREX project looked at two other important technologies which help to maximise renewable generation.
The first was a liquid-based battery, specifically a Vanadium Redox Battery (VRB). The purpose of the VRB was to capture excess wind generation when available and to use this to smooth the variable output of the wind farm to make this more manageable in the system. Vanadium Redox Battery (VRB) tanks This battery system showed some early promise, but being an emerging technology it was subject to plant outages and was unfortunately not able to deliver on a sustained basis, prior to an eventual plant failure. As with other R&D activities, Hydro Tasmania has learned from this demonstration project and incorporated those learnings in our current battery projects. The VRB has since been decommissioned and with the rapid advance of battery technology in recent years this is planned to be replaced by a more proven technology in 2013.
The final element of KIREX was a substantial upgrade to the existing power station controls. This new system allowed the operators to optimise the operation of the power system as a whole, balancing renewable generation, energy storage and diesel generation with load while keeping the system reliable for our customers.
Vestas tower sections being erected 5 Resistive Frequency Control and Photovoltaic Solar Installation
Photovoltaic Solar panel
In 2008 two further technologies were added to the King Island power system. Solar generation was added by a third party and Hydro Tasmania developed a new and promising technology which enables the system to use more of the available renewable energy generation.
The solar installation on King Island is owned by KI Solar Pty Ltd (a subsidiary of CBD Energy Ltd) and adds approximately 100kW of renewable energy to the King Island Power Station. The six solar photovoltaic arrays can rotate on a dual axis to track the path of the sun.
Because no single renewable energy source is perfectly placed to generate all of the time, having two or more sources is important for a remote system like King Island.
The Resistive Frequency Control system is a technology which, simply put, allows our wind turbines to operate unhindered, providing as much energy as the wind will allow, and converts this to more useful energy reserves to offset diesel generation.

To achieve this, the project brings together a portfolio of next for new and existing technologies to increase renewable energy use on King Island. An innovative aspect of this system is the integration of these technologies. King Island?

9 Stage 1 King Island Renewable Energy Integration Project (KIREIP) Diesel uninterruptible power supply (D-UPS) Two diesel-uninterruptible power supply (D-UPS)units have now been installed at the King Island Advanced Hybrid Power Station. Each D-UPS unit contains a large mass flywheel, which uses excess wind energy rather than diesel power to maintain its motion. Its diesel engine operates only rarely when the unit is required to provide power for an extended period, otherwise the mass of the flywheel carries sufficient energy to provide the power response.
Although D-UPS is a well-proven commercial technology, common in airports and data centres, the application of these units in a remote power system of this size is a world first.
In the King Island system the D-UPS allows all primary diesel generation units to be switched off when there is a period where renewable energy generation is greater than the customer demand, resulting in what is called 100 per cent renewable energy penetration.
Without the D-UPS, switching diesel units completely off would present a problem. If the wind generation were to reduce rapidly the primary diesel generators would not be able to be switched back on fast enough – resulting in a gap in power generation and a blackout.
This is where the D-UPS comes in.
The D-UPS provides an immediate short-term backup for the primary diesel generators – it makes sure that there is not a gap in generation when the customer demand rapidly exceeds renewable generation.
The flywheel of the D-UPS contains significant inertia and if renewable generation drops, the inertia of the flywheel can quickly start the attached secondary diesel generator. The D-UPS unit can cover the gap for enough time to allow a larger primary diesel engine to be started.

The completion of the D-UPS is a huge step in the King Island renewable energy journey allowing the island to have periods where it is powered by 100 per cent renewable energy.
Upgraded high voltage switch gear New high voltage (HV) switch gear was also installed and commissioned as part of the first stage of KIREIP. While the HV gear is a supporting element to other major project elements, such as the D-UPS, it is vital to the success of the project. One of the diesel-uninterruptible power supply units The new HV switch gear provides the connection points for the new equipment and will increase electricity supply reliability and allow our team to test new equipment while maintaining power supply to customers.
Power station building extension On the more practical side of things, this first stage of the project also required additional space for new technologies. An extension to the existing station was completed before any of the new technology arrived. Space for the D-UPS, HV switch gear and a new space to permanently house the resistor as well as offices for the operational staff and a meeting room to showcase the project were included in the station extension. The upgraded high voltage switch gear
The extended King Island Advanced Hybrid Power Station Showcase centre – explaining how the technologies are integrated 11 Stage 2 King Island Renewable Energy Integration Project (KIREIP) Wind farm expansion An increase in the wind farm capacity is planned for King Island. The increase in renewable wind generation will allow for a greater percentage of time running the system at 100 per cent renewable penetration.
The wind farm expansion is made possible because the enabling nature of the D-UPS and the fact that with the diesels able to be switched off significantly more customer load can be met by wind energy.
The wind farm expansion is an important element in demonstrating the high level of contribution renewable energy can play in modern remote power systems utilising innovative enabling and storage technologies. Smart Grid The Smart Grid component of KIREIP looks beyond the generation component of power supply to the demand or customer side.
The Smart Grid is the next phase in the evolution of the electrical power generation, transmission and distribution system. In the King Island context the Smart Grid aims to match customer demand to the available supply as much as possible through the use of communication technologies and a ‘smart’ control system.
The Smart Grid project will focus on the dynamic and rapid direct control of customer loads in order to maintain the system demand/supply balance under increased levels of renewable energy supply, providing a more efficient and reliable power system.

13 Remote area power supply in Australia and around the world
Seth Langford and Andrew Ling of Entura working on a project for the remote community of Cape Barren Island
There are many thousands of remote communities, as well as commercial projects and mine sites throughout Australia and the world that rely on diesel generation for power in remote area power supply systems. In many instances the high cost of diesel power generation prevents them from receiving a continuous electricity supply, greatly impacting their quality of life and productivity.
The innovative solutions developed under KIREIP have enormous potential to increase the use of renewable energy and reduce reliance on diesel fuel for power generation on islands and in off-grid systems across the globe, reducing the cost of energy services and the exposure to volatile oil prices. Pitcairn Island
As a leader in renewable energy Hydro Tasmania is intent on pursuing how King Island can be used as a blueprint for other power systems across the world.
14 Research and development
Mike Ross of Entura developing Smart Grid equipment with Brook Sneldon of Cambium Networks
Hydro Tasmania has implemented KIREIP as a unique opportunity to develop and deploy innovative world-leading renewable and enabling technology in a sizeable, real-world ‘closed system’.
We believe that the applied R&D conducted in the design and operation of King Island system, with very high levels of renewable energy, will be deployed over time within the larger mainland Australian power system and similar global networks.
Knowledge generated through the completion of the development program will be instrumental in realising solutions to manage high levels of intermittent renewable energy penetration in the National Electricity Market, helping to achieve the mandated 20 per cent renewable energy target by 2020.
Hydro Tasmania has received significant interest in the work being undertaken on King Island, including from leading research groups such as the University of Tasmania, CSIRO, Sandia National Labs and Pacific Northwest National Laboratories. We are seeking ongoing collaborations with research institutions to promote the utilisation of KIREIP Dusan Nikolic of Entura and Patrick Nogara of Hitzinger commissioning one of the diesel-uninterruptible power supply units for applied R&D.
