Abstract: Micro grid comprises of various Distributed Energy Resources, Battery Energy Storage System (BESS) and various loads that can be connected to a grid or can be operated in an isolated mode. In this paper, micro grid comprises of a Diesel Generator set, wind turbine generator, Battery Energy Storage System (BESS) to feed a critical load in an isolated location. The intermittent energy from wind power is stored in BESS and a Centralized micro controller program is used to schedule the operation of Diesel Generator and BESS to provide an uninterrupted power supply to the critical load. The communication link between the microcontroller and Distribution Energy Resources will be a satellite link (GPRS/3G/4G/5G) or optical fibre cable. The main objective of this work is to reduce the usage of diesel generator output and utilizing the renewable energy in place of it to its maximum capacity. Meanwhile by proper scheduling, continuous working of BESS is ensured within its SOC limits. In this work, MATLAB simulation is used to simulate the load sharing among Diesel Generator and BESS. A hardware prototype is designed in proteus software and the hardware prototype is fabricated to verify the simulation results.
