Abstract :
This paper presents an on/off-grid integrated photovoltaic power generation system and its control strategy. The system consists of PV, lithium battery, public grid, converters and loads. The system can work on both on-grid condition and off-grid condition depending on the operation states of PV and lithium battery. The lithium battery works as an energy storage device coordinating with PV to realize energy management. A 5 kW prototype is built to verify the validity of the control strategy.
