This paper highlights the key results from the Renewable Electricity (RE) Futures Study. It is a detailed consideration of renewable electricity in the United States. The paper focuses on technical issues related to the operability of the U.S. electricity grid and provides initial answers to important questions about the integration of high penetrations of renewable electricity technologies from a...
This paper illustrates an analysis of the power generation expansion plan of the Hellenic Interconnected Mainland System as an aspect of the National Renewable Energy Action Plan (NREAP) of the country for the year 2020. The modeling background and a description of the incorporated technologies are thoroughly provided. In addition, major conclusions of the scenarios investigated are analyzed, and...
Renewable energy sources will play an increasingly central role in the power network of the future. The will to reduce the dependence on fossil sources as well as growing environmental awareness, both individually and governmentally, is forcing governments throughout the world to invest an enormous amount of capital in renewable energy sources. The European Union, through its Energy and Climate Policy,...
Since 2004 changes in the regulatory framework of the Chilean public and electricity sectors have been taken place (19940 law in March 2004). Transparency rules must be following by the market agents in pricing procedures of the electricity market. Consequently, technical, economical, and reliability data of the Chilean power system are available for simulation and optimization purposes. The Chilean...
Electricity infrastructure touches us all - the key challenge, pertinent to this panel session, is to enable secure and very high-confidence sensing, communication and control of a heterogeneous, widely dispersed, yet globally interconnected system, which is a serious technological problem in any case. It is even more complex and difficult to control it for optimal efficiency and maximum benefit to...
Electric power systems are entering a new realm of operations. Large amounts of variable generation tax our ability to reliably operate the system. Couple this with a greater reliance on the electricity network to serve consumer demand that is likely to rise significantly even as we drive for greater efficiency. Trade-offs between energy and environmental needs will be constantly negotiated, while...
The process of price formation in an electricity market is an extremely complex one in practice due to different endogenous factors, namely generator gaming, unexpected out-ages and transmission congestion, among others. As a result, the market clearing prices are of stochastic nature, bringing about uncertainty and risk to all participants. In this work, the role of the demand as determining factor...
The distributed energy resources customer adoption model is used to estimate the value an Oakland nursing home, a Riverside high school, and a Sunnyvale data center would need to put on higher electricity service reliability for them to adopt a consortium for electric reliability technology solutions microgrid (CM) based on economics alone. A fraction of each building's load is deemed critical based...
Various ancillary services are needed in a deregulated power system to ensure the electricity to be delivered reliably and the system is operated securely. Spinning reserve is one of these ancillary services which a reasonable amount of such reserve is essential to satisfy system security constraints when the power system faces with a contingency. In this paper, Emergency Demand Response Program (EDRP)...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
