The Danish EDISON project has been launched to investigate how a large fleet of electric vehicles (EVs) can be integrated in a way that supports the electric grid while benefitting both the individual car owners and society as a whole through reductions in CO2 emissions. The consortium partners include energy companies, technology suppliers and research laboratories and institutes. The aim is to perform...
The aim of the present paper is that of assessing the role of the transmission system in a liberalized electricity market, pointing out that the presence of transmission capacity limits may influence the market outcomes and above all it may make profitable a strategic behaviour rather than a competitive one by one or more producers. From this point of view, the transmission system development becomes...
This paper describes an alternative method for grid expansion planning considering construction cost, probabilistic production cost, congestion cost and outage cost of a grid at a composite power system derived from a simulation model. In this paper, a heuristic scenario method is proposed to choose the least cost solution (scenario) among various scenarios considering candidate new lines. The characteristics...
The integration of renewable energy sources such as wind power into power systems is quite difficult due to their stochastic nature. As wind power penetration begins to reach significant levels these difficulties can mean great financial expenses and increased carbon emissions. In this paper we demonstrate that through smart utilization of multiple generation sources, a technique we call integrated...
A methodology based on the security-constrained unit commitment (SCUC) is applied to analyze the transmission congestion in the Eastern Interconnection of the United States for 2008 and 2018. The proposed SCUC tool for this study is referred to as the POwer Market Simulator (POMS). The identified congestions are visualized along with the Geographical Information System (GIS) data and compared with...
This paper describes the top-down value based transmission planning process for Eastern Wind Integration and Transmission Study (EWITS) with the consideration of large scale wind generation over the Eastern Interconnect footprint. Achieving 20% to 30% wind energy penetration across the Eastern Interconnect will require significant transmission infrastructure expansion. The transmission overlays developed...
The strive for sustainable energy systems will most likely lead to an increased use of renewable energy sources which to a large extent are fluctuating. Therefore, a larger demand for balancing capacity will be required to maintain system security. Plug-in Hybrid Electric Vehicles (PHEV) represent a potential storage which could offer additional balancing power. Here, the applicability of PHEVs for...
This paper discusses a novel approach for analysis of large scale real time grid operation performance. The PJM Interconnection energy market is one of the largest centralized markets in the world. Recently PJM deployed a newly developed application called “Perfect Dispatch” designed to provide a baseline measure of grid operational performance using retroactive real time market simulation and analysis...
A number of states in the United States have taken collaborative actions to control for greenhouse gas (GHG) emissions from state governmental level. The effort by the western and the eastern states is called the Western Regional Climate Action Initiative and Regional Greenhouse Gas Initiative (RGGI), respectively. RGGI is a collaboration by 9 states in the northeast United States targeted at regional...
Wind speed variability generates the main challenges for grid integration of wind power. Worldwide, requirements governing generator connection to the transmission grid evolve as the modern energy industry continues to develop. With increased wind power penetration, wind power plants are required to provide grid support and control actions similar to conventional power plants. Dedicated control systems...
The paper focuses on the importance of demand management and load control for the development of electric power system and the provision of electricity supply reliability. The potential of controllable loads in Russia is estimated including electric vehicle transport, climate systems, household, industrial and agricultural consumers. The potential and optimal volumes of perspective controllable loads...
The role and application of energy storage and dynamic reactive power support is discussed in this paper. A well-engineered energy storage plant can help alleviate some of the problems encountered with the integration of intermittent renewable resources and at the same time make renewable power plants more cost effective in existing traditional power system. The intent of this paper is to demonstrate...
This paper assesses the effects of the future European power generation system with strict CO2 emission reduction targets on the planning of cross-border interconnection lines. Results from a techno-economic energy systems model have been used as input to this work, regarding the development of the European power generation system until the year 2050, meeting the EU 2020 CO2 target and a 85% emissions...
This paper presents updated results from a Monte Carlo simulation method of operational needs created by variable generation renewables coupled with a Production Simulation methodology to assess whether the California ISO's existing generation fleet can provide the needed flexibility for ramping, load following and Regulation under a 20% Renewable Portfolio Standard. The production simulation methodology...
The Puerto Rico Electric Power Authority (PREPA) supports an orderly development of the renewable energy potential on the islands. To attain this goal, PREPA is conducting science-based analytical studies and research to increase knowledge on these technologies. As part of this effort, PREPA commissioned the Electric Power Research Institute (EPRI) to assess the potential impacts that different penetration...
Paper: Integrating Renewables into Markets and Operations at High RPS Levels - Discussion of Issues and Recent Efforts at Understanding High RPS Impacts on Real Time System Performance.
This paper represents a modified dynamic programming solution to the unit commitment (UC) problem. The UC is a complex decision-making process because of multiple constraints which may not be violated while finding the optimal or suboptimal commitment schedule. There are many methods to solve the UC problem gradually. So, before we present our method, we will show the drawbacks of the standard dynamic...
We present an incentive policy design model consisting of lower level and upper level optimization to promote renewable energy. The lower level optimization is a generation expansion planning (GEP) problem, in which the planner aims to expand an energy system's generation capacity to serve projected load with minimum cost. In the upper level optimization, to achieve the goal of specific percentage...
This paper presents a general framework for Microgrids control based on Multi Agent System Technology. The proposed architecture is capable to integrate several functionalities, adaptable to the complexity and the size of the Microgrid. To achieve this, the idea of layered learning is used, where the various controls and actions of the agents are grouped depending on their effect on the environment...
The penetration level of wind power into the power system over the world have been increasing very fast in the last few years and is still keeping the fast growth rate. It is just a matter of time that the wind power will be comparable to the conventional power generation. Therefore, many transmission system operators (TSOs) over the world have come up the grid codes to request the wind power plants...
