Abstract

This paper proposes an energy management control system (EMCS) to manage and optimize power in dc microgrid system. The system consists of PV, AC grid and energy storage to supply the dc loads in the office building. The dc microgrid system and the EMCS module are built based on the MATLAB/Simulink platform. The suitable constraints such as the limit value of SOC of the system for the next day’s condition are obtained by considering from the day ahead predicted values of PV power and load demand. Based on those constraints, power supply priority of system sources and real-time operation algorithm, the real time control signals of PV, AC grid and the battery are performed to control and optimize the system energy and reduce supplying time of AC grid. The PV is controlled between maximum power point tracking (MPPT) and load demand power point tracking (LPPT) algorithms due to the limitations of the energy storage system.
