Firefly Algorithm based Optimal Reactive Power Flow

The optimal reactive power flow (ORPF) helps to effectively utilize the existing reactive power sources for minimizing the network loss. Firefly Algorithm (FA), inspired by social flashing behavior of fireflies, is one of the evolutionary computing models for solving multimodal optimization problems. This paper attempts to obtain global best solution of ORPF using FA. The results of IEEE 57 bus system are presented to demonstrate its performance.
