Abstract

This paper presents a residential power system that mainly includes photovoltaic (PV) panels, a hybrid energy storage system (HESS), a grid, and converters. The multimodal operation caused by the large number of states for each of the units increases the complexity of the system operation. It is difficult to adjust the operation state in the face of emergencies. A multimodal simplification method is proposed to simplify multimodal operation into three dominant modes (PV, HESS, and load) according to an energy management flowchart. A novel control strategy is proposed to realize the internal power distribution of the HESS, as well as the power allocation between the HESS and a single-phase full-bridge converter (SFC), while smoothing the double fluctuation of the bus voltage caused by the SFC. The effectiveness of the proposed multimodal simplification and control strategy is verified through the simulation and experimental results from a PV-HESS-grid.
