Biobjective Optimal Reactive Power Flow Using Chemical Reaction Based Optimization

Abstract

The optimal reactive power flow (ORPF) helps to effectively utilize the existing reactive power source with a view to minimize the network loss and improve voltage profile. The chemical reaction optimization (CRO), inspired from the interactions of molecules in a chemical reaction to reach a low energy stable state and searches for optimal solution through reactions involving the on-wall ineffective collisions, decomposition, inter-molecular ineffective collision and synthesis. This paper attempts to develop a global best solution method that simultaneously minimizes the network loss and enhances the voltage profile for ORPF using CRO. The results of IEEE 30 bus system are presented to demonstrate its performance.
