Abstract

This article aims to reduce power losses and improve system reliability by determining the optimal number, location and size of Photovoltaic Distributed Generators (PV-DG). The PV-DG is modeled as a negative load, draws reactive power from grid and injects real power to the grid. Optimum allocation of PV-DGs and their sizing is obtained by harmony search algorithm (HS) and teaching-learning-based optimization (TLBO) approaches. IEEE 33-bus distribution system was successfully demonstrated by the proposed approach. HS has proven its superiority against TLBO algorithm as it uses less DGs rating devices to enhance distribution system performance. The new contribution in this research is to optimize the number of DGs and does not operate with a given number of DGs (1 DG, 2 DG ,…..) as most of previous works. Another contribution is to study the optimization under several loading conditions.
