An analysis of Economic Load Dispatch with Ramp-rate limit constraints using BSA

Economic Load Dispatch (ELD) plays an important role in advanced power system operation and control in recent times. ELD problem was solved by many types of optimization techniques. Here a new optimization method namely Backtracking Search Algorithm (BSA) technique has been used to solve the Economic Load Dispatch problem and compared with Particle Swarm Optimization with Constriction Factor Approach (PSOCFA). A practical nonlinear constraint like ramp rate limit has also been considered. In this paper the proposed optimization technique shows its maximum effectiveness and optimality of result by using fifteen unit and forty unit test system.
