PSO Technique for Solving the Economic Dispatch Problem Considering the Generator Constraints

Dr. L.V.Narasimha Rao

By economic dispatch means, to find the generation of the different units in a plant so that the total fuel cost is minimum and at same time the total demand and losses at any instant must be met by the total generation. The classical optimizations of continuous functions have been considered. Various factors like optimal dispatch, total cost, incremental cost of delivered power, total system losses, loss coefficients and absolute value of the real power mismatch are evaluated for a simple system by hand calculation. The MATLAB programs were developed to solve Economic Load Dispatch Problem of an n-unit Plant through lambda iterative method and Particle Swarm Optimization
