ABSTRACT

This paper presents a Particle Swarm Optimization (PSO) Technique for Real and Reactive power allocation. In order to optimize the power allocation for a system (power system), a non-linear optimization problem is formulated. The proposed method utilizes the fuel cost coefficient of the generators, transmission losses upper limit and lower limit of the various generating units to optimize power allocation. A Power system with three generating units is considered. Assumed load demands of 200MW is used to compute the power allocation of the 3 generating units as well as the optimized operational cost. The optimized power allocations for the three generating units are obtained by MATLAB scripts on a Matlab 7.5 running on a windows vista operating system. 

Keywords: Particle Swarm Optimization (PSO), Global Best (gbest), Personal Best (pbest), Unit Commitment (UC).
