Deregulation is, restructuring the rules and economic incentives that the government setup to control and drive the Electric Supply Industry (ESI). It is also called as open power market, competitive power market, vertically unbundled market etc. With the introduction of deregulation, the electric power industry needs changes in various power system operation, control and planning activities. In this...
In electricity spot markets, revenue of independent power producers (IPPs) is dependent on successful bidding strategies. This research establishes a model for strategic bidding and short-term generation scheduling in reserve co-optimized markets like the Philippine Wholesale Electricity Spot Market. The model, which is applicable to independent power producers, is based on the combination of security...
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...
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...
National energy system was regarded as one kind of complex adaptive system, pointing out that it covers four adaptive agents, that is the agent of energy production, the agent of energy consumption, the agent of government and the agent of research institute. On the basis of this understanding, the adaptive mechanism of energy enterprises (including the agent of energy production and energy consumption),...
Electricity markets are designed and operated based on physical constraints of modern power systems. This panel will review the practices on post-contingency congestion mitigation with market forces, from the perspectives of market design and market operation. Future challenges will be also discussed.
As a financial instrument for hedging risk, financial transmission right (FTR) has been put into application in some power markets. Based on AC optimal power flow (OPF) a new FTR auction model was proposed under considering of the contingency constraints. With the n-l static security constraints, this model is solved by the AC-OPF based on Monte Carlo simulation. Firstly the contingency set is selected...
This paper describes a transmission expansion planning method based on multi-objective optimization (MOOP). The method starts with constructing a candidate pool of feasible expansion plans, followed by selection of the best candidates through MOOP, of which multiple objectives are tackled simultaneously, aiming at integrating the market operation and planning as one unified process in the market environment...
Market operators are required to effectively manage transmission line, particularly as congestion occurs where energy prices are different at all nodes in the network. Locational marginal prices (LMP) have been extensively recognized as an appropriate solution in managing transmission congestion. This paper investigates formulation of LMP schemes using different approaches; DC optimal power flow and...
The problem of cross border interchange and of exchange capacity allocation has gained an increasing importance because of existing price gaps between the different countries and of limited exchange capacity. The European Transmission System Operators (ETSO) committee has issued a sequence of documents illustrating the guidelines for efficient and economic assignment of the available cross border...
Voltage control and reactive power support have been deeply investigated by the technical point of view. System operators and planners have developed complex control schemes, in order to achieve a secure and efficient operation. After the enforcement of market structures, new issues have appeared. Nowadays, the main subjects related with the reactive power management are: maintaining an adequate security...
The zonal approach is now broadly adopted by electricity markets worldwide, since it provides the participants with an easily understandable representation of the transmission constraints. The zonal approach and the total transmission capability (TTC) interact in the sense that the higher is the TTC, the lower is the influence of transmission constraints on market results. As a consequence the TTC...
This paper examines leading business and technological drivers for high performance computing, and presents example applications that stress today's computation limits.
Security constrained optimal power flow programs are important tools for ensuring correct dispatch of supply while respecting the many constraints imposed by the delivery system. In addition to getting the dispatch right, locational prices must be calculated with equal precision in order to infuse market participants with the proper incentives for operation and investment. In this paper we discuss...
The problem of cross border interchange and of allocation of exchange capacities between interconnected countries of the European Community has gained an ever increasing importance during the most recent years. The reasons for that are to be found in the existing price gap between different countries as well as in the limited exchange capacity of some interconnection corridors. As a result, the European...
Ensuring power system reliability is among the top responsibilities of an RTO/ISO. Focusing on operating reliability, this panel will review the PJM's practices on reliability related risk management from the power system operations and market operations viewpoints, recognizing the interrelationship between system and market operations. On one hand, system study, outage coordination and reliability...
