Abstract

In the deregulated electricity market, the power generators profit depends on its unit scheduling, bidding strategies and on the market price. The coordination of wind energy with other renewable resources serve an effective way for the generating companies to increase its payoff. Accordingly, the wind power with hydro power system coordination incur the enhancement of power dispatch and thereby reducing imbalance prices. This paper proposes an interval optimization technique to solve the price based unit commitment problem. It also suggests to solve the bidding strategy with the accurate intervals. Variations in wind hydro power, the volatilities in day ahead energy price, intra hour energy price are considered as periodic numbers. Comparing to the conventional technique it is easier to determine and optimizes the entire profit intervals. Henceforth, has an inherent advantage on computational complexity and associates under worst case scenarios.
