Economic Load Dispatch Using Genetic Algorithm Optimization Technique

In the power system, "Economic load dispatch" means the generation of electricity is low of cost and the power system constraints such as Real power and Reactive power vary within the specified limits while fulfill the load demand of the power system. Main objective of the ELD problem is to minimize the total fuel cost. The total cost of operation includes the cost of fuel, transmission cost, labor cost and cost of maintenance. The two major factors to be considered while dispatching power to generating units are the cost of generation and the quantity of power supplied. The relation between the cost of generation and quantity of power supplied is expressed in a polynomial equation and it is solved by applying of mathematical technique. The suggested optimization techniques have a merit in finding an optimal solution. In this research paper we apply basically genetic algorithm and simulated algorithm. We have tested the applied algorithm on IEEE 30 bus system and 20-unit generator system.
