Pacific DC Intertie (PDCI) Upgrade Outage / De-Rate Schedule 2014
Version No. Pacific DC Intertie (PDCI) Upgrade 10 POWER SYSTEM Effective Outage / De-rate Schedule 2014-2016 1/12/2016 Date: Introduction The upcoming scheduled outages due to major upgrades on the Pacific DC Intertie (PDCI) will result in reduced available capacity on the line during various periods from 2014 to 2016. Most of the upgrades are convertor station and line work by the Bonneville Power Administration (BPA) to modernize its infrastructure at the Celilo Converter Station, which is the northern terminal of the PDCI. Other work will be performed by the Los Angeles Department of Water and Power (LADWP) in conjunction with the upgrades. Scheduling MW Capacity The schedule below will be updated as outages are scheduled. Start Date End Date Direction Scheduling Capacity (MW) June 28, 2015 October 3, 2015 North – South 1956 HE21 HE3 South – North 975 October 3, 2015 January 20, 2016 North – South 0 HE4 HE24 South – North 0 January 21, 2015 North – South 29901 HE1 South – North 975 From October 3, 2015 to January 21, 2015, the Celilo‐Sylmar Pole 3 1000kV Line and Celilo‐Sylmar Pole 4 1000kV Line will be removed from service and the PDCI will not be available [0MW (N‐S) and 0MW (S‐ N)].

The History of High Voltage Direct Current Transmission*
47 The history of high voltage direct current transmission* O Peake† Power Systems Electrical Engineer, Collingwood, Victoria SUMMARY: Transmission of electricity by high voltage direct current (HVDC) has provided the electric power industry with a powerful tool to move large quantities of electricity over great distances and also to expand the capacity to transmit electricity by undersea cables. The fi rst commercial HVDC scheme connected the island of Gotland to the Swedish mainland in 1954. During the subsequent 55 years, great advances in HVDC technology and the economic opportunities for HVDC have been achieved. Because of the rapid development of HVDC technology many of the early schemes have already been upgraded, modernised or decommissioned. Very little equipment from the early schemes has survived to illustrate the engineering heritage of HVDC. Conservation of the equipment remaining from the early projects is now an urgent priority, while the conservation of more recent projects, when they are retired, is a future challenge. 1 INTRODUCTION technology for the valves to convert AC to DC and vice versa. At the beginning of the electricity supply industry there was a great battle between the proponents In the late 1920s, the mercury arc rectifi er emerged of alternating current (AC) and direct current as a potential converter technology, however, it was (DC) alternatives for electricity distribution. This not until 1954 that the mercury arc valve technology eventually played out as a win for AC, which has had matured enough for it to be used in a commercial maintained its dominance for almost all domestic, project. This pioneering development led to a industrial and commercial supplies of electricity number of successful projects. -

Advanced Transmission Technologies
Advanced Transmission Technologies December 2020 United States Department of Energy Washington, DC 20585 Executive Summary The high-voltage transmission electric grid is a complex, interconnected, and interdependent system that is responsible for providing safe, reliable, and cost-effective electricity to customers. In the United States, the transmission system is comprised of three distinct power grids, or “interconnections”: the Eastern Interconnection, the Western Interconnection, and a smaller grid containing most of Texas. The three systems have weak ties between them to act as power transfers, but they largely rely on independent systems to remain stable and reliable. Along with aged assets, primarily from the 1960s and 1970s, the electric power system is evolving, from consisting of predominantly reliable, dependable, and variable-output generation sources (e.g., coal, natural gas, and hydroelectric) to increasing percentages of climate- and weather- dependent intermittent power generation sources (e.g., wind and solar). All of these generation sources rely heavily on high-voltage transmission lines, substations, and the distribution grid to bring electric power to the customers. The original vertically-integrated system design was simple, following the path of generation to transmission to distribution to customer. The centralized control paradigm in which generation is dispatched to serve variable customer demands is being challenged with greater deployment of distributed energy resources (at both the transmission and distribution level), which may not follow the traditional path mentioned above. This means an electricity customer today could be a generation source tomorrow if wind or solar assets were on their privately-owned property. The fact that customers can now be power sources means that they do not have to wholly rely on their utility to serve their needs and they could sell power back to the utility. -

2002 ABB ELECTRIC UTILITY CONFERENCE HVDC Technologies
2002 ABB ELECTRIC UTILITY CONFERENCE PAPER IV – 3 POWER SYSTEMS HVDC Technologies – The Right Fit for the Application Michael P. Bahrman ABB Inc. 1021 Main Campus Dr. Raleigh, NC 27606 Abstract: Traditional HVDC transmission has often provided economic solutions for special transmission applications. These include long-distance, bulk-power transmission, long submarine cable crossings and asynchronous interconnections. Deregulated generation markets, open access to transmission, formation of RTO’s, regional differences in generation costs and increased difficulty in siting new transmission lines, however, have led to a renewed interest in HVDC transmission often in non-traditional applications. HVDC transmission technologies available today offer the planner increased flexibility in meeting transmission challenges. This paper describes the latest developments in conventional HVDC technology as well as in alternative HVDC transmission technologies offering supplemental system benefits. Keywords: HVDC, DC, CCC, VSC, PWM, RTO, Asynchronous, HVDC Light I. INTRODUCTION Economic signals arising from deregulation of the generation market have led developers and transmission providers alike to follow the path of least resistance much like the power flow over the network on which their mutual business interests rely. On the generation side, the developer has invoked a quick-strike strategy siting units where there is convergence of low-cost fuel supplies, relative ease of permitting, water supply, ready access to transmission and proximity to load. On the transmission side, the transmission provider has been preoccupied with cost reduction, compensation for stranded assets, potential under-utilization of assets and reacting to evolving regulatory mandates. Although such development may result in a short-term gain in new, economic power resources, the long term benefit is not all that clear. -
