Energy Management System for PV-DC Generator Based Microgrid for Rural Homes

This paper presents a energy management system (EMS) for a photovoltaic-fuel DC generator based microgrid system for home. The proposed system is based on the following objectives: (i) To Ensure Load sharing among sources. (ii) To reduce the power loss and increase efficiency of the photovoltaic system with the implementation of MPPT Algorithm. (iii) To make the system economically viable by using DC Generator as a backup instead of designing a specific battery bank. To improve the system's reliability and power quality, a proportional-integral (PI)-based controller is designed to operate a DC generator as a backup to maintain microgrid stability when there is a power shortage at the DC bus bar due to low PV power generation or excess load. The DC generator then begins to supply the load. The performance and control strategy of proposed EMS is verified using MATLAB Simulink.
