Research of hybrid PV inverter with energy storage function

This electronic document is a Photovoltaic power generation can be divided into off-grid mode and grid-connected mode. Hybrid photovoltaic inverter which is composed by combining these two kinds of working modes is the trend of future development. However, there are still deficiencies in the switching problems among off-grid mode, grid-connected mode and stop mode. In view of these phenomena, this paper puts up with relevant solutions and also sets up a simulation model and experimental platform. The experimental results and conclusions are given through experiment.
