During the use of electricity, the power grid is powered down due to the occurrence of maintenance or some faults. When power failure occurs, if the solar photovoltaic power generation equipment cannot be immediately disconnected from the power grid, an island effect is generated, namely, the phenomenon that power output by photovoltaic power generation and peripheral electric loads generate independent power supply outside the power grid. Once the phenomenon occurs, damage to users and power grid maintenance personnel is likely to occur, safety accidents are likely to occur, and the voltage frequency cannot be stable, so that some power supply facilities are damaged. Therefore, the related problems must be solved or the manner must be changed to sufficiently and effectively popularize the photovoltaic power generation.
