Sustainable energy management for hybrid photovoltaic/wind/grid power generation system [articol]

Abstract

Recently, renewable energy sources became more attractive, due to increasing energy needs and factors like limited reserves, increasing energy costs and environmental pollution. As these sources don’t cause any environmental pollution and have an unlimited supply, it is extensively utilized day by day. Solar and wind are the two renewable sources considered in this paper. In renewable energy system, a smart power management system is essential to maintain sustainability of this energy. Since solar and wind are the renewable sources which required a better power management system, thereby they fullfil the raising power demand, but their reliability it terms of power quality and sustainability are doubtful. In the renewable energy system, the generated power is collected on a common DC bus which is used for supplying to load. This DC power bus is operated in an extensive manner that, there is a base power available for permanent loads for ever. Then, depending upon the availability of those power sources, the extra power demand is provided from either PV or wind source. The whole system is operated by a smart management system with the help of the fuzzy logic method. The fuzzy based smart management system which determines the amount of power to be supplied based on the power information from a solar / wind system. The smart power management system will measure and track the availability of the maximum generated power from wind system that increases the installed unit’s efficiency. The result obtained will prove in an effective manner power management system.
