Autonomous Control of Interlinking Converter with Energy Storage in Hybrid AC-DC Microgrid

Due to the decade of fossil fuels, renewable energy plays an important role to supply the power to meet our load requirements. The main drawback of renewable energy system is its installation cost is very high and renewable energy sources are mainly unpredictable. To eliminate the drawbacks in renewable energy, hybrid system plays a major role. Hybrid system is an interconnection of two or more sources. In this project solar energy and battery are used as a two different sources. Power from the solar energy is boosted by boost converter and boost converter act as a impedance matching network. When internal impedance of solar is matched with the boost converter impedance power will be transfer from source to load. Battery power is boosted by boost converter and output of solar and battery added together and given as a input to the inverter. To connect the 3 phase line to the microgrid it is necessary to find 3 phase network. Hence BLDC motor is used as load because it is used to verify the 3 phase network. The proposed design has an advantage i.e., battery bank and solar panel acts as a source, hence the uninterrupted power obtained to run the system
