UNIT COMMITMENT IN ECONOMIC DISPATCH ELECTRIC POWER SYSTEM

Abstract

The problem of unit commitment (UC) is to determine the optimal plan of  generation unit in order to minimize cost and meet constraints such as power balance, power reservation and other operating conditions. In a power system, there are normally many types of power plant, however, the problem of UC on this paper only consider thermal units. The paper proposes modeling of UC  problem for thermal units and apply BARON Solver for solving the problem. Calculating results of a power system with 10 thermal units during 24 hours of dispatching, and comparison to other method such as GA (Gennetic Algorithm), MA (Memetic Algorithm), EP (Evolution Programming) have demostrated the effectiveness and correctiveness of the model and method of calculating.
