Abstract
An exercise of power effectively of renewable energy is more important than power generation. This paper proposes stand alone wind energy system (WES) for a rural area with uninterrupted power. Power Point Tracking (PPT) is ordinarily involved in wind systems to maximize the output power from wind generator regardless of the weather changes. Though the sensor less control of tip speed ratio (TSR) is preferred at most, incorporation of the high speed digitized wind gauge replaces the complexity in the closed loop drive of turbine generator. Wind power output capacity, however, is still low and the associated costs still high, so efforts continue to develop WES converter and its controller, aiming for higher power-extracting efficiency and cost effectiveness. For many applications, uninterrupted power is essential. In this proposed system, the Wind energy system with Battery Energy Storage System (BESS) is contributed in the power system for continuous power. Efficient utilization of wind power decides the efficiency of power system. Bidirectional DC-DC converter and Power source selector (PSS) controls the source of power to load. PSS controls charging and discharging of BESS without any wastage of wind power so that the chance of using fossil fuel get reduced. The simulation for switching sequences of PSS is presented.
