The provision of operating reserve in power systems is revisited in the context of the deregulated power industry and of competitive power markets. The operating reserve is stand-by capacity that must be kept ready to generate energy to provide for unplanned outages of generating units. The former problem of establishing reserve requirements in the regulated industry has turned into the questio...

From the optimization point of view, an optimum solution of the unit commitment problem with reliability constraints can be achieved when all constraints are simultaneously satisfied rather than sequentially or separately satisfying them. Therefore, the reliability constraints need to be appropriately formulated in terms of the conventional unit commitment variables. In this paper, the reli...

Abstract- In a typical competitive electricity market, a large number of short-term and long-term contracts are set on basis of energy price by an Independent System Operator (ISO). Under such circumstances, accurate electricity price forecasting can play a significant role in improving the more reasonable bidding strategies adopted by the electricity market participants. So, they cannot only r...

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 reli...

A group of energy resources (including energy storage units) physically distributed in the network which are placed under a unified and integrated management with a central control system is called a Virtual Power Plant (VPP). The bidding strategy of a VPP, as a participant in energy and reserve markets, has significant role in maximizing its profit. This paper proposes a new mathematical appro...
