Modelling and Control of a Stand-Alone Hybrid PV-Wind Micro-Grid System

Abstract

Microgrids are quickly becoming a necessity for the future of electricity. The use of renewable energy sources provides a viable alternative to traditional methods of producing electricity. Generation of electricity via traditional energy sources has severe consequences for the natural world and for human well-being. Renewably sourced energy is widely available across the cosmos. Renewable energy is dependable, efficient, sustainable, and clean. Wind and solar power are becoming increasingly important in today's society. This paper details the design and control of a stand-alone micro-grid that utilises a Permanent Magnet Synchronous Generator (PMSG) powered by photovoltaic cells and a wind energy conversion device. In order to ensure efficient functioning of a microgrid system despite non-linear parameter fluctuations, a novel intelligent control approach based on ANFIS control has been presented. The designed system was constructed in MATLAB/Simulink and simulated under constant load and step load variations. The BESS was able to charge thanks to the controllers, despite fluctuations in the load and other external parameters like irradiance and wind speed.
