ELD of Power Network in Southwest of Iran (Khuzestan Province) Using JAY A Technique

Abstract

Power load flow studies are the mainstays of analyzing and designing power systems, and doing so is essential for scheduling production between power companies and economic utilization. The distribution of economic load in today's world is the most important goal of energy distribution in dispatching centers. In industry, the production capacity of generators is usually much larger than the loads, so the allocation of loads in the generator can be varied. Since reducing the cost of electricity generation is important and the highest cost of production is related to the cost of fuel, so load sharing must be done economically. Finally, energy distribution professionals must take control of power plant production at the lowest cost. In this paper, the Economic Load Dispatch (ELD) problem of a sample power system is investigated by JA YA effective computational algorithm and the results are compared with Lambda iteration method. Theoretical backgrounds and mathematical formulations for these two methods are also provided. The power system studied in this research is the power network of southwestern Iran (Khuzestan province), which includes eight power plants. These calculations are performed by excluding network losses as well as by continuously assuming the cost function of power plants. Finally, the fuel cost of the power plants of the sample power system is compared using the JA YA algorithm and the classical Lambda iteration method. Comparison of the obtained results shows that these two methods are suitable in providing efficient solutions to economic load distribution problems in large electricity networks. All simulations have been performed in MATLAB software.
