This paper deals with the rising interest for circulated age dependent on Renewable Energy Sources (RES) has prompted a few issues in the activity of utility networks. The microgrid is a promising answer for take care of these issues. A committed energy stockpiling framework could add to a superior combination of RES into the microgrid by smoothing the inexhaustible asset's irregularity, improving the nature of the infused power and empowering extra administrations like voltage and recurrence guideline. However, due to energy/power technological limitations, it is often necessary to use Microgrid Storage Systems. A second order sliding mode controller is proposed for the power flow control of a microgrid, utilizing a Four Leg Three Level Neutral Point Clamped (4-Leg 3LNPC) inverter as the main interface between the RES/BESS and the microgrid. The adequacy of the proposed method for the microgrid system power flow control is contrasted with an established PI control plot and is demonstrated through simulation and tentatively utilizing a 4 Leg 3LNPC model on a test bench.
