Real-time platform for controlling DC microgrid based standalone solar energy conversion system

This paper presents a control strategy for solar energy conversion system for DC microgrid. The energy system includes a storage device for standalone applications. Incremental conductance method has been adopted for maximum power point tracking in order to improve the efficiency of the system. The bidirectional converter, placed between the battery and the DC-link voltage, is controlled to charge/discharge the battery according to the generated power and to keep the DC-link voltage constant. Real time simulator has been used for parallel and distributed computing to maximize the controller efficiency. The proposed system is experimentally tested using OPAL-RT real time simulator.
