Comparison of different optimization techniques for optimal allocation of multiple distribution generation

Abstract

This paper aims to present and compare a number of optimization algorithms techniques namely, Whale Optimization Algorithm(WOA), Dragonfly Algorithm (DA) and Moth-Flame Optimization (MFO) algorithm. These approaches have been implemented to identify the optimal location and sizing of distributed generation (DG) in radial distribution systems considering minimization of network power losses. In this regard, multiple-DG units are simultaneously allocated and analyzed under two load power factors (i.e., unity and optimal). The proposed algorithms have been tested on the 69- and 119-bus radial distribution systems. The performance of the competitive algorithms has been compared with other evolutionary optimization methods under different system operating conditions in terms of all measures. The simulation results show the effectiveness of installing the proper size of DG at the suitable location based on different techniques.
