In support of work to assess and ensure the reliability and resiliency of Florida's power generation, transmission, and distribution system as load and generation evolve in future years, groundwork is presented for the development of an open, dynamic model of the Florida grid and geographically distributed projections for growth in load and generation within the state. Using load forecasts provided...
This paper describes the process required to adapt a conventional EMS Simulator for testing the Real-Time Electricity Market. The paper discusses the need and requirements for the simulator. CAISO's traditional EMS Dispatcher Training Simulator was modified and coupled with CAISO's Market Applications to act as a real time Market and Grid Operation Simulator. This new simulator provides realistic...
A new optimal power flow (OPF) model accounts for electro-thermal coupling relationship is established based on electro-thermal coordination (ETC) concept in this paper This new OPF model organically combines the traditional OPF with heat balance equation (HBE) which reflects thermal dynamic process of transmission component. It considers the temperature limit of transmission component as its security...
Flywheel energy storage can provide ancillary services including regulation and frequency response to power grids. This study presents the technical characteristics, modeling approach, methodologies, and results for providing regulation services in the California Independent System Operator market. Breakeven cost analyses were developed for two cases: (1) the flywheel provides the regulation service...
The debate on which is the best incentive for transmission expansion is still active. Discussions center on economic mechanisms based on game theory to expand transmission. There is a mix of experiences and they vary in function of the level of interaction of market agents. Identifying the agents' strategies will allow a better understanding of the market's dynamics. This article assesses regulatory...
California Independent System Operator Corporation (CAISO) is a not-for-profit public benefit corporation in charge of managing the electricity flow along California's open-market wholesale power grid. Recently, the CAISO implemented the nodal LMP electricity market based on full network model and upgraded its infrastructure with new state of the art technology. The implementation of new electricity...
An offshore power transmission grid in Northern Europe has become a serious and important topic among the power industry, the power transmission sector, national governments and the European Commission. The OffshoreGrid project will provide policy recommendations for the political process towards such a grid in pursuing the efficient integration of renewables, the integration of market regions, security...
The combination of offshore wind generation with international transmission cables is a highly discussed topic in Europe, especially for the North Sea and the Baltic Sea. The offshore wind park location Kriegers Flak in the Baltic Sea could combine offshore wind generation in the Swedish, German and Danish zones, and several design options with regard to cabling are under discussion. Choosing a certain...
Protection security assessment of power grids becomes an important task in the course of a competitive energy business and a decarbonized power generation. The analysis of past blackouts studied by the North American Electric Reliability Council (NERC) shows that protection relays are involved in about 75% of all major disturbances. One reason for that is the non adequate adaption of the protection...
Ireland has some of the most favourable wind conditions in the whole of Europe. Wind production, in the mainland as well as offshore, is expected to grow rapidly during the coming years, as evidenced by the fact that some 6000 MW of wind generation is currently awaiting connection to the grid onshore. Given the massive potential for the exploitation of renewable energy resources off the coast of Ireland,...
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...
