Maximum Power Point Tracking of Grid Connected Solar Wind Hybrid System

Abstract

The use of renewable energy technology to meet the energy demands has been increasing for the past few years. However the important drawbacks associated with renewable energy system are their inability to guarantee reliability and their intermittent nature. At present standalone solar, photovoltaic and wind system have promoted on a larger scale. Standalone solar energy system cannot provide reliable power during night time non-sunny days. The standalone wind system cannot satisfy constant load demands due to fluctuation in the magnitude of wind speeds from hour to hour through out the year. Therefore, energy storage system will be recure for each of these systems in order to satisfy the power demands which are expensive and the size has to be reduced to a minimum possible for the renewable energy system to be cost effective. Hybrid power system can be used to reduce energy storage requirements and for economical operation it is desirable to operate the system in its maximum power point value. The purpose a method is to operate the wind solar hybrid system at its maximum power point by using sufficient power electronic device and corresponding control method.
