Optimal Location and Sizing of Photovoltaic System in Kerman Distribution Network by Multi-objective Index

This research has studied and analyzed optimum capacity and location of production system of photovoltaic energy in 15-bus and 70-bus distribution systems in Kerman using several various indexes such as reactive losses, active losses, voltage regulation, conductor capacity and indexes of single-phase and three-phase short-circuit based on load flow algorithm of forward-backward. Moreover, owning to physical properties of photovoltaic modules in radiation conditions and different temperatures such as V-I and P-V curves, maximum power point tracking is used by an optimum interface circuit which is a reducer inverter of PWM with variable output. In this case, the conditions were supplied to receive the maximum power from distribution system and a photovoltaic power system with energy saver along with interface circuit was connected and synchronized to distribution system in order to receive the maximum power point. It will be also indicated that the effect of distributed generation resources of photovoltaic systems on voltage profile improvement and losses reduction is more than the system without distributed generation sources; it shows function improvement of the suggested method.
