Employing Renewables to Effectively Cut Load in Electric Grids
GreenPeaks: Employing renewables to effectively cut load in electric grids Raphael Luciano de Pontes1, Aditya Mishra2, Anand Seetharam3, Mridula Shekhar2, Arti Ramesh3 1Dept. of Computer Science, Federal University of Minas Gerais, Brazil 2Dept. of Computer Science & Software Engineering, Seattle University, USA 3Dept. of Computer Science, SUNY Binghamton, USA [email protected], [email protected], [email protected] [email protected], [email protected] Abstract—Reducing the carbon footprint of energy generation net metering is one of the most popular approaches that allows is an important part of ongoing sustainability efforts. To cut customers to integrate their onsite renewable deployments carbon footprints, electric utilities are incentivizing renewable with the electric grid. It allows customers to generate onsite energy integration through net metering and introducing time- of-use pricing plans to cut demand peaks, as peaks significantly electricity (e.g., using solar panels); generated energy is used contribute to both generation costs and carbon emissions. Net to satisfy customers demand, and any surplus generation is metering is one of the most popular means of integrating sold back to the grid. In its current form, net metering has distributed renewable generation in the grid. However, the two crippling limitations: 1) it doesnt adequately cut peaks, current net metering approach doesn’t effectively cut demand as energy harvest peaks and demand peaks are out of sync; peaks because renewable harvest peak and demand peaks are out of sync. Furthermore, as several states impose net metering for instance, solar power harvest peaks earlier in the day, but subscriber limits of less than 1% of the peak, net metering isn’t household peak demands typically occur around dinner times; even close to realizing the full potential of renewable integration 2) many states impose subscriber limit to less than 1% of the in the grid. -

SEGU MADAR MOHAMED RIFAI Student Number: 731222 A-315 Approved Examiner Supervisor at KTH Date: 05/06/2012 Prof. Björn Palm Dr. Samer Sawalha Local Supervisor Dr. Hari Gunasingam Commissioner Contact person i | P a g e Abstract Demand for cooling has been increasing around the world for the last couple of decades due to various reasons, and it will continue to increase in the future particularly in developing countries. Traditionally, cooling demand is met by decentralised electrically driven appliances which affect energy, economy and environment as well. District Cooling Plant (DCP) is an innovative alternative means of providing comfort cooling. DCP is becoming an essential infrastructure in modern city development owning to many benefits compared to decentralized cooling technology. Demand Response Management (DRM) is largely applied for Demand Side management of electrical grid. Demand of electrical energy is closely connected with the demand of alternative form of energy such as heating, cooling and mechanical energy. Therefore, application of DR concept should be applied beyond the electrical grid; in particular, it could be applied to any interconnected district energy systems. District Cooling Plant is one of a potential candidate and Demand Response management solutions can be applied to DCP for sustainable operation. -

DOE's Office of Electricity Delivery and Energy Reliability
DOE’s Office of Electricity Delivery and Energy Reliability (OE): A Primer, with Appropriations for FY2017 Updated December 13, 2016 Congressional Research Service https://crsreports.congress.gov R44357 DOE’s Office of Electricity Delivery and Energy Reliability (OE) Summary The nation’s energy infrastructure is undergoing a major transformation. For example, new technologies and changes in electricity flows place increasing demands on the electric power grid. These changes include increased use of distributed (mostly renewable energy) resources, Internet- enabled demand response technologies, growing loads from electric vehicle use, continued expansion of natural gas use, and integration of energy storage devices. The Department of Energy’s (DOE’s) Office of Electricity Delivery and Energy Reliability (OE) has the lead role in addressing those infrastructure issues. OE is also responsible for the physical security and cybersecurity of all (not just electric power) energy infrastructure. Further, OE has a key role in developing energy storage, supporting the grid integration of renewable energy, and intergovernmental planning for grid emergencies. As an illustration of the breadth of its activities, OE reports that, during FY2014, its programs responded to 24 energy-related emergency events, including physical security events, wildfires, severe storms, fuel shortages, and national security events. OE manages five types of research and development (R&D) programs, usually conducted in cost- shared partnership with private sector firms. OE also operates two types of deployment programs, conducted mainly with state and tribal governments. Each OE program office has its own set of goals and objectives. OE plays the central role in two of DOE’s broad cross-cutting initiatives: grid modernization and cybersecurity. -

However, the interactions between a higher number of electric vehicles and the impacts on power plant capacities have not been sufficiently investigated yet. Hence, this paper develops an approach to evaluate the energetic impacts on current power plant capacities that result from a higher market penetration of electric vehicles by 2030. The key aspect of the approach is the quantification of smart charging processes in energetic and economic perspectives. It was found that the implementation has significant energetic and thus economic benefits because of an improved integration of the additional electricity demand. The value of information systems which enable smart charging processes is shown by the calculated cost-saving potentials, resulting from a reduced expansion of the power plant system. Keywords Electric Mobility, Smart charging processes, Security of Energy Supply, Economic Appraisal INTRODUCTION Over the last decades, there has been continuous growth of the demand for individual mobility, seen particularly in increasing car sales. However, recent trends indicate a fundamental paradigm shift in the automotive industry. This trend has been initiated by a gradual substitution of electric vehicles1 (EVs) for vehicles with a combustion engine (Urbschat and Bernhart, 2009). -
Comparing Electricity Generation Technologies Based on Multiple Criteria Scores from an Expert Group
Comparing electricity generation technologies based on multiple criteria scores from an expert group Euan Mearns*1 and Didier Sornette1.2 ETH Zurich 1Department of Management, Technology and Economics Scheuchzerstrasse 7 , CH-8092 Zurich, Switzerland 2Institute of Risk Analysis, Prediction and Management (Risks-X), Academy for Advanced Interdisciplinary Studies, Southern University of Science and Technology (SUSTech), Shenzhen, 518055, China [email protected] [email protected] * Corresponding author. Highlights: • 13 common electricity generation technologies were evaluated using multi criteria decision analysis (MCDA) where values were assigned by the expert judgment of a professional group. • A hierarchical scheme of 12 criteria organized into 5 categories of health, environment, grid, economics and resources was used to provide a holistic measure of energy quality. • The three leading technologies to emerge are nuclear power, combined cycle gas and hydroelectric power. The three trailing technologies are solar PV, biomass and tidal lagoon. • Our findings are consistent with the baseline cost approach of the 2004-2009 EU funded NEEDS project but contrast sharply with the MCDA survey of the same project that found CaTe solar PV and solar thermal power to be the most promising technologies for central Europe. Abstract: Multi criteria decision analysis (MCDA) has been used to provide a holistic evaluation of the quality of 13 electricity generation technologies in use today. A group of 19 energy experts cast scores on a scale of 1 to 10 using 12 quality criteria – based around the pillars of sustainability – society, environment and economy - with the aim of quantifying each criterion for each technology. The total mean score is employed as a holistic measure of system quality. -

Maria Aslam Vehicle to Grid Concept As Part of Power System and Electricity Market
MARIA ASLAM VEHICLE TO GRID CONCEPT AS PART OF POWER SYSTEM AND ELECTRICITY MARKET Masters of science thesis Examiner: Prof. Pertti Järventausta Examiner and topic approved by the Faculty Council of the Faculty of Computing and Electrical Engineering on 5th October 2016 i ABSTRACT MARIA ASLAM: Vehicle to grid concept as part of power system and electricity market Tampere University of Technology Master of Science Thesis, 55 pages January 2016 Master’s Degree Programme in Electrical Engineering Major: Smart Grids Examiner: Professor Pertti Järventausta Keywords: EV, RES, V2G, Intelligent charging The demand of electricity is increasing day by day with the increase in world’s population. Renewable energy sources (RES) are being integrated into the smart grid system. Renewable energy sources have fluctuating nature such as wind and solar power, and thus accurate forecasting of generation from these sources is nearly impossible. At the distribution end, load forecasting is also challenging as the load demand is not constant all the time. Hence to deal with the intermittent nature of RES and to fulfil the peak load demand, there is a need for a storage system that can be integrated with the smart grid environment. Electric vehicles (EVs) serve this purpose and replace the internal combustion engine vehicles in transportation. They are considered as mobile energy storage systems which do not only reduce the environmental pollution but also provide power to the grid in peak load time by storing energy in their batteries at off peak times when the demand is quite low. The aim of this thesis is to understand the concept of V2G.
