Abstract

The main objective of the proposed system is to provide uninterrupted power supply to the load systems, which are located at isolated sites in remote and rural areas. The main goal of the proposed system is to set up an energy management system (EMS) on a DC microgrid using the nonlinear model predictive control (NMPC) and maximum power point tracking (MPPT) algorithms. We suggest a coordinated and flexible EMS that uses a photovoltaic array and a wind turbine as generators that can be controlled by changing the switching duty cycles. Batteries are used as a storage system. The proposed EMS needs to be more flexible with the power curtailment feature in order to achieve a constant current, constant voltage (IU) charging regime and make batteries last longer. Based on each system's MPPTs, the suggested plan is made as a nonlinear model predictive control (NMPC) algorithm. The entire designed system is modeled and simulated using MATLAB/Simulink.
