Optimal Scheduling of Short Term Hydrothermal Coordination for an Indian Utility System Using Genetic Algorithm

Abstract

This paper addresses short-term scheduling of two test hydrothermal systems by using Genetic algorithm. Short-term hydrothermal coordination consists of determining the optimal usage of available hydro and thermal resources during a scheduling period of time.Genetic algorithm is applied to determine the optimal hourly schedule of power generation in a hydrothermal power system. The developed algorithm is illustrated for a test system an Indian Utility System which consists of 7 hydro and 4 thermal systems respectively. The effectiveness and stochastic nature of proposed algorithm has been tested with standard test case and the results have been proved to be better than conventional method and results obtained by the proposed method are superior in terms of fuel cost.
