Abstract – Energy is one of the most important resources for the growth of any country. Wind energy is playing an important role in meeting today’s words energy demand. Renewable energy sources are intermittent in nature. Such uncertainty results in revenue losses to the wind power producers. The main objective of this paper is to focus on the analysis of performance of an open loop AC-DC-DC converter system. Converter is simulated using PSIM software.

I. INTRODUCTION

In India development of wind energy started in early 1950s. Indian wind energy system holds fourth position in the world with total installations having crossed the 31 GW mark at the end of March 2017. The total renewable energy capacity installed in the country crossed the 50 GW mark. Among renewables, wind power accounted for over 57 percent of the installed capacity [1].Need for reducing global warming and significant increase in the prices of conventional energy sources have encouraged many countries to provide new energy policies that promote the renewable energy applications. They are cost effective, user-friendly. By promoting renewable energy sources we can avoid, Air pollution, soil pollution and water pollution. Country’s Economy will increase [2]. They are the most economic power plant technology, due to reduced installations costs, no fuel costs and construction time of less than one year, compared to over 10 years to construct nuclear power plants [3]. But these renewable energy sources are intermittent in nature. Such uncertainty results in revenue losses to the wind power producers. Instead wind power producers can purchase or schedule some reserves to offset part of their deviation rather than being fully penalized in the real-time market [4].
