A framework for analyzing competitive electric power systems has been developed. A model and simulation based upon the framework, as well as applications and extensions, are presented. The applications include an analysis of the potential gains from trade of a large-scale synchronous interconnection between the Electric Reliability Council of Texas (ERCOT) and the Southwest Power Pool and a stu...

Deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. In this paper, generation reliability is considered and a method for its assessment using intelligent systems is proposed. Also, because of power market and generators’ forced outages stochastic behavior, Monte Carlo Simulation is used for reliability evaluation. Generation relia...

The target of an oligopolistic generating company in a pool-based electric power market is to maximize its profits using two related instruments at hand: 1) its ability to modify the market-clearing price and 2) its capability to alter its own production level. Power balance is not an issue for the generating company; the independent system operator ensures power balance considering generator a...

In this country development of electrical power system particular for transmission line expansion and interconnection of neighbouring power system try to improve system security and economic operation. Due to this province in large scale power system, operation , control and expansion planning for particular system become challenging task to reduce transmission loss as minimum as possible for o...

This paper proposes an index for nodal market power detection in power market under locational marginal pricing (LMP). This index is an ex-ante technique to detect the market power. More precisely, this criterion detects the potential of exercising market power regardless of detecting the actual market power. Also it is obvious that pricing and market clearing method affect the potential of exe...

Electric vehicle (EV) aggregator, as an agent between the electricity market and EV owners, participates in the future and pool market to supply EVs’ requirement. Because of the uncertain nature of pool prices and EVs’ behaviour, this paper proposed a two-stage scenario-based model to obtain optimal decision making of an EV aggregator. To deal with mentioned uncertainties, the aggregator’s risk...

this paper proposes a novel decision making framework for an electricity retailer to procure its electric demand in a bilateral-pool market in presence of charging and discharging of electric vehicles (evs). the operational framework is a two-stage programming model in which at the first stage, the retailer and ev aggregator do their medium-term planning. determination of retailer's optimum sel...

This paper simulates a pool-based electricity market and identifies equilibrium patterns. A multiperiod framework that requires the use of continuous and binary variables is considered. Producers can be either price-takers or price-makers, although price-makers and their behavior characterize the market. The elasticity of the loads is modeled through piecewise constant pricedemand curves. The m...

In this paper, a new structure for reactive power market is presented. Considering reactive power losses caused by active power flow in the reactive power market is the main purpose of this paper. Hence, this study tries to improve reactive power market and create fair competition in reactive power generation.
