Cooperative Multiple Particle Swarm Optimization (CMPSO) and Spatial Extended Particle Swarm Optimization (SEPSO) For Solving Reactive Power Optimization Problem

Reactive Power Optimization is a complex combinatorial optimization problem involving non-linear function having multiple local minima, non-linear and discontinuous constrains. This paper presents Cooperative Multiple Particle Swarm Optimization (CMPSO) and Spatial Extended Particle Swarm Optimization (SEPSO) in trying to overcome the Problem of premature convergence. CMPSO and SEPSO are applied to Reactive Power Optimization problem and are evaluated on standard IEEE 30Bus System. The results show that CMPSO prevents premature convergence to high degree but still keeps a rapid convergence. It gives best solution when compared to Spatial Extended Particle Swarm Optimization (SEPSO).
