Hybrid power system with integration of wind, battery and solar PV system

Hybrid power system with integration of wind, battery and solar PV system

Abstract:

This paper presents a renewable energy hybrid power system based on photovoltaic (PV) and wind, and equipped with Cuk DC-DC converter, three phase inverter and LC filter. The wind and PV energy are suitable for hybrid system because they are environmental friendly and widely available in India. However, the hybrid power system that solely depends on the intermittent renewable energy sources generates a fluctuating output voltage that leads to damage to the machines operating on a stable supply. The modeling of the hybrid system with Cuk converter, three phase inverter and LC filter are done using MATLAB Simulink. Blocks such as wind model, photovoltaic model, Cuk converter, inverter and LC filter are built separately before combining into a complete DC voltage hybrid system with main grid of power system. Different irradiance value and varying wind speed are the input parameters for the project simulation. The results show that hybrid system has better reliability in terms of output voltage generation as compared to standalone system. In addition, Cuk DC-DC converter, three phase universal bridge based inverter and LC filter that are installed in the hybrid system are able to reduce the fluctuation output voltage.
