Solar PV based Autonomous Low Voltage DC Microgrid for Remote Electrification

The low-voltage DC microgrids (LVDC-MGs) have gained considerable popularity among stakeholders, researchers/engineers and have created a new trend for the development of microgrids, with the benefits of reduced conversion loss and simple control, as generation and storage technologies such as photovoltaic (PV) and battery storage have improved efficiency at a decreased cost. However, appropriate control schemes are critical for incorporating the source and load variations. The voltage stability and power-sharing between renewable energy sources (RESs) and energy storage systems (ESSs) within the microgrid are important concerns concerning stability and reliability. The performance of the proposed work is demonstrated in MATLAB Simulink for stand-alone LVDC MG with PV arrays and ESSs and analyzed under the variation of solar irradiance, which was found to be suitable for remote household electrification. The results achieved from the simulation illustrated an autonomous DCMG capable of supplying the daily energy requirements of the system with decent voltage stability.
