REDUCTION OF REAL POWER LOSS BY UNIFIED ALGORITHM

In this paper, we propose a new Unified Algorithm (UA) by combination of Variable mesh optimization algorithm (VMO) with Differential Evolution (DE) for solving reactive power problem. VMO has mainly three search operators, one for global exploration and two for local optima exploitation. DE is a simple yet commanding evolutionary algorithm for solving optimization problems. In all iteration VMO serve as the initial population of DE and obtains a population of more quality with this population VMO begins a new cycle. The proposed UA has been tested in standard IEEE 30 bus test system and simulation results show clearly about the better performance of the proposed algorithm in reducing the real power loss with control variables within the limits.
