The implementation of emission certificates in Europe in 2005 has lead to new uncertainties especially for power companies resulting in additional costs for the power generation. The introduction of certificates goes along with political conditions and objectives particularly in the European Union until 2020. In consequence, these regulations take influence on the power plant scheduling as well as...
Before deregulation, th Korea Electric Power Corporation (KEPCO) had been a vertically integrated monopoly over power generation, transmission, and distribution. However, the generation competition market based on Cost based pool (CBP) began in April, 2001. The KEPCO generation department has been allocated into six independent GenCos. Before the reform of the power industry that took place in South...
Deregulated electricity markets in the U.S. currently minimize total bid costs to select bids and their generation levels but determine payments based on market clearing prices. The inconsistency between auction and settlement mechanisms can lead to a significantly higher consumer payment. This gives rise to the “payment cost minimization,” an alternative auction mechanism that minimizes consumer...
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...
In this paper, an enhanced congestion control scheme for market related applications is presented. Based on the concept of Marginal Value Expansion, violated transmission constraints can be handled more effectively in the optimization process. Compared to the traditional congestion control method, available resources in system can be utilized more sufficiently. The effectiveness of the new scheme...
Demand Response (DR) provides mechanisms and incentives for utilities, business and residential customers to reduce energy use (and costs) during time of peak demand or when system reliability is at risk. DR is considered by CPUC, DOE and FERC as one of high-priority Smart-Grid Functionalities. FERC has developed a national action plan on demand response, recognizing that a more extensive use of demand...
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...
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...
Negotiation of secure bilateral transactions has become an important issue for better operation, planning and management of competitive electricity markets. In this paper, secure bilateral transactions have been determined with minimum deviations in economic generation schedule and real power losses for hybrid electricity markets. The generation pattern and real and reactive power loss has been obtained...
The present transmission system was not designed to work efficiently as a means of delivering large amounts of renewable energy. Large amounts of wind energy and the RTO energy markets have increased the need for transmission to deliver energy off peak and improve the efficiency of the energy markets. Papers and reports have been written that describe the use of generation optimization and power system...
This paper proposes a novel technique to forecast day-ahead electricity prices based on Panel Cointegration (PC). The current researches on the electricity price forecasting focus on the analysis of unstable economic time series. However, due to the difference of the allocation of power resource and consumption in different regions, the time series of electricity consumption and sales price in a single...
Network pricing analysis has always been complex for distribution networks due to the data size involved. Simplified reference network models help to reduce the data to be handled, and hence the associated complexity. These models provide a test system to assess the investment consequences of applying different network charging approaches and analyze the impact of such approaches on customer end prices...
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...
Locational marginal price (LMP) is a fundamental principle in the majority of electricity markets and is increasingly being employed at a number of ISO's such as PJM, california ISO, etc. It is essential to obtain the accurate value of LMPs. This paper presents an OPF formulation with a composite dynamic load models which is a composite of ZIP and induction motor loads. An improved locational marginal...
This paper contributes to the discussion about the future integration of Smart Grids in the existing energy supply system on a mostly economical and regulatory point of view. One of the main issues in this case is the increasing costs due to grid enhancements under regulated grid tariffs. On the one side a concept based on an integrative customer oriented approach is described and the new roles of...
Our analysis shows that there is likely to be minor short term risk or reward for electric utilities with respect to electric vehicle adoption, but also that significant long term value or risk exists, depending on how judiciously utilities manage pricing, charging and infrastructure. The margin of difference between profit and loss lies with the extent to which customer adoption is clustered, whether...
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...
