Fuzzy based hybrid incorporating wind solar energy source by reduced harmonics

Abstract

The demand for electricity is increasing very rapidly due to the vast development in industrialization. Generally, at present, for electric power generation, Renewable Energy Sources (RES) are considered as a better alternative option than conventional energy sources. Among the various RES, Solar and wind energy are available in abundantly and hence they can be recognized as a reliable source of power generation. More over this type of Hybrid solar and wind energy systems can be used for rural electrification and modernization of remote area. However, there will be problem of power quality issues such as harmonics, sag etc., hence, this work proposed a novel methodology to improve the power quality of the grid system interfaced with hybrid wind-solar system. In this proposed methodology, shunt active power filter with fuzzy logic based control strategy is introduced to minimize the harmonics present in the system. The proposed topology is validated through dynamic simulation using the MATLAB/Simulink Power System Toolbox. Simulation results demonstrate that the proposed system injects power into the grid from hybrid system with harmonic mitigation. This approach also eliminates the need of additional power conditioning equipment for the improvement of power quality.
