Hydro generation scheduling for deregulated and competitive operation

In this paper a new approach is presented for short-term optimal scheduling. of large hydro generators under deregulated and competitive electricity industry environment. Fuzzy regression model is applied to estimate the range of uncertain market prices. Optimal scheduling problem is solved by Lagrange relaxation to maximize the difference between the total revenue and the total cost. The proposed approach is tested on a numerical example based on real power system data.
