A SEIG-Based DC Nanogrid for Rural Electrification

The Government of India has launched several schemes for rural electrification by enhancing the penetration of renewable energy resources. This paper aims toward a DC nanogrid for rural electrification in India. The DC nanogrid consists of a self-excited squirrel cage induction generator, PV panel, a battery storage for smooth and reliable operation, and compatible converters for voltage regulation and required conversion. The proposed DC nanogrid has been modeled and simulated in MATLAB/Simulink. The proposed system maintains a constant 120 V DC at load terminal. The performance of WECS has been analyzed in the environment of MATLAB/Simulink, and the same has been validated using a prototype hardware developed in the laboratory.
