Abstract
The rapid adoption of renewable energy technology has made the microgrid concept to be widely accepted in modern power systems. Renewable energy resources in DC microgrids operate intermittently which affects the power supply and the load. This has made the bus voltage control to become very difficult. Linear controllers, such as PI and PID, are mature and widely used for controlling the microgrid bus voltage, nonetheless, their performance is not optimal when system parameters change. This paper proposed a strategy for controlling the DC bus voltage using a sliding mode controller. The proposed controller is tested on a DC microgrid incorporating a PV system, Battery storage system, and load. The effectiveness of the proposed methodology has been verified in a Matlab/Simulink environment. The result from the simulation shows that the proposed sliding mode control can keep the DC bus voltage stable by managing the BESS's charging and discharge in the event of variations in solar irradiation and varying load demand.
