Particle Swarm Optimization with Time Varying Acceleration Coefficients for Solving Economic Load Dispatch Problem

The Particle Swarm Optimization with Time Varying Acceleration Coefficients (PSOTVAC) is proposed in this paper to solve Economic Load Dispatch (ELD) with various generator constraints in power systems. Actually the proposed problem is considered as an optimization problem. The basic objective of ELD of electric power generation is to schedule the committed generating unit outputs, so as to meet the load demand at minimum operating cost while satisfying all unit and system equality and inequality constraint. For practical generator operation, many nonlinear constraints of the generator, such as ramp rate limits, prohibited operating zone, generation limits, transmission line loss and non-smooth cost functions are all considered using the proposed technique. The proposed algorithm applied on different test standard power system. The effectiveness of the proposed method is compared with other heuristic algorithms. Results showed the efficiency of the proposed algorithm
