Analysis of a Solar Wind Integrated Energy System using Sepic Converters

This paper introduces, Design and Analysis of hybrid solar wind energy system using two SEPIC converters. Wind energy is among the worlds fastest growing sources of energy. Solar energy has the greatest potential of all the sources of renewable energy when other sources have depleted. The power Electronics play crucial role of conversion and control of electric power. Therefore power electronics based power converters are also broadly used in renewable energy systems. This project presents a new system of configuration of the rectifier stage topology for a hybrid wind/ photovoltaic energy system in order to simplify the power system and reduce the cost. This configuration allows the two sources to supply the load separately or simultaneously depending on the availability of the energy sources. The proposed design is the fusion of two SEPIC converters. The inherent nature of these SEPIC converters eliminate the need for additional input filters to eliminate high frequency harmonics. Harmonic content is determined for the generator lifespan, heating issues and efficiency. The fused multi input converter stage also allows maximum power point tracking (MPPT) algorithm to be used to extract maximum power from the sun when it is available. When a source is unavailable or insufficient in meeting the load demands. The other energy sources can compensate for the difference. The proposed design is mathematically modelled which is simulated via MATLAB software.
