A Particle Swarm Optimization for Reactive Power Optimization

This paper presents implementation of new algorithm Particle Swarm Optimization (PSO) for Energy Saving through minimizing power losses. The PSO Algorithm Solution is tested in standard IEEE 30 Bus system. The objective is to optimize the reactive power dispatch with optimal setting of control variables without violating inequality constraints and satisfying equality constraint. Control Variables are of both types: Continuous and Discrete. The continuous control variables are generator bus voltage magnitudes;whereas the discrete variables are transformer tap settings and reactive power of shunt compensators (Capacitor banks) .
