Electrical power system is divided into three main components, namely power generation, electricity transmission, and distribution of electricity. Power generation is the biggest cost component in an electrical power system. The analysis to minimize generational costs is called economic dispatch. The meaning of economic dispatch is the division of loading on existing generating units in the system optimally and economically at a certain load price. Economic Dispatch is considered the heart of economic operation of a power system. With the implementation of economic dispatch it will get a minimum cost of generation of electricity generation. In this work, economic load dispatch has been done to find out the minimum operating cost for the generating units of Al-khums power station. Simulation results show the effectiveness of the proposed method in optimizing the operating cost for studied system
