This paper presents hybrid system, which combines photovoltaic systems, battery and super capacitors, for energy demand and load response. Energy production of the photovoltaic system is changeable, so that energy storage for setting up energy balances, regulation and voltage protection is absolutely vital. In this article, modeling, simulation and controlling hybrid system, which consists of photovoltaic system, battery and super capacitor, also maximum power point tracer algorithm is taken. In addition, the stability of micro-grid and lifetime of the battery is shown. The simulation results show that suitable switching of power electronic converters in this system applies proper controlling over photovoltaic power and battery and super capacitor storages charge and discharge, which leads photovoltaic system acts in the high-efficiency area and to increase the battery life and reduce economic costs due to it, is that of the great achievements of this research.
Keywords: Battery, Hybrid System and DC Micro Grid, Lifetime, Photovoltaic, Super Capacitor
