Abstract
Photovoltaic systems (PVS) are among the fastest growing energy resources in the world. Most of the PVS had been installed in the distribution systems as distributed generation. Conventionally, distribution systems are designed and operated based on the assumption of centralized generation, with the corollary that the power flows from the distribution substation to the end-use customers. The problem for correct sizing and positioning of PVS distributed generation in distribution systems is of great importance. For that reason, the use of an optimization method capable of indicating the optimal sizing and position for a given distribution network can be very useful. In this work, particle swarm optimization (PSO) algorithm is presented to simultaneously determine the optimal size and location of PVS in a given distribution system network.
