CONDITION OF SUBSTANCE SEARCH ALGORITHM FOR SOLVING REACTIVE POWER PROBLEM
Keywords:Condition of Substance Search, Exploration & Exploitation, Optimal Reactive Power, Transmission Loss
In this paper, Condition of Substance Search (COS) algorithm is introduced to solve optimal reactive power dispatch problem. The Condition of Substance Search (COS) algorithm is based on the simulation of the shape of substance incidence. In Condition of Substance Search (COS) algorithm, individuals follow molecules which interrelate to each other by using evolutionary operations which are based on the corporal principles of the thermal-energy motion mechanism. The algorithm is developed by considering each condition of substance in harmony with different exploration–exploitation ratio. The evolutionary progression is alienated into three phases which emulate the three condition of substance: solid, liquid & gas. This technique can considerably improve the equilibrium between exploration–exploitation, however preserving the high-quality search ability of an evolutionary approach. The proposed Condition of Substance Search (COS) algorithm has been tested on standard IEEE 30 bus test system and simulation results show clearly the improved performance of the projected Condition of Substance Search (COS) algorithm in reducing the real power loss and voltage stability also enhanced.
