Power Management Controller for Renewable Energy based hybrid AC-DC Microgrid

Abstract

The study proposes an AC-DC microgrid powered by a combination of renewable energy sources. Appliances that require either direct current (DC) or alternating current (AC) can be powered using this system. Solar photovoltaics and wind power systems are the most practical alternatives because of their widespread availability and low maintenance requirements. Solar PV electricity fluctuates owing to the altered in temperature and irradiance and is unable to generate consistent power, so a storage battery system is required to meet up the power demand and preserve the fidelity of the hybrid microgrid. Thus, a DC microgrid system has been built, comprising BS plus the solar PV system with DC load, and an AC micro grid system, comprising a wind turbine generator, a connection to the grid, and an AC load. A power regime controller is used to regulate the ratio of AC to DC current. As a further step towards validating the suggested system's efficacy, it has been built in MATLAB/Simulink.
