This paper presents a fuzzy particle swarm optimizer to solve the economic load dispatch (ELD) problem of thermal generators of a power system. Several factors such as quadratic cost functions with valve point loading is considered in the computation models. The Fuzzy particle swarm optimization (FPSO) provides a new mechanism to avoid premature convergence problem with optimum solution. The proposed method has been applied to 3 and 40 generator power system whose cost functions are non-convex in nature. Results obtained by this method have been compared with those obtained by PSO method. The experimental results show that proposed FPSO method is capable of obtaining optimum solution in fewer numbers of iterations.
