چکیده
The Strength Pareto Gravitational Search Algorithm (SPGSA) to solve Economic Load Dispatch (ELD) is presents this paper with various generator constraints in power systems. The ELD problem in a power system is to determine the optimal combination of power outputs for all generating units which will minimize the total fuel cost while satisfying all practical constraints. 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 algorithm. Results showed the efficiency of the proposed algorithm.
