[0002] Distributed photovoltaic power generation refers to photovoltaic systems installed near user sites. These systems are usually directly connected to low-voltage power grids and are mainly used to meet the power demand at the site. When the power generation exceeds the local consumption, the excess power can be fed back to the power grid.
