Hybrid power management strategy for portable device using fuzzy logic controller

The world is driving its energy needs mainly by depending on fossil fuels. Fossil fuels causes emission of carbon gases which causes green house effect and hazardous problems. So it's better we opt for hybrid sources such as solar energy, wind energy etc. This paper mainly emphasis in presenting a strategic hybrid energy management which consists of PV (photovoltaic), WG (wind generator) and battery. The algorithm is designed in such a way that PV has the highest priority of available sources. The management algorithm mainly aims at reducing the cost of overall system, increasing the battery life and to provide uninterrupted power supply to the load at all instant.
