Description

technical field

[0001] The invention relates to a solar photovoltaic power generation technology, in particular to a distributed photovoltaic power generation system and an intelligent cluster control method. Background technique

[0002] The video surveillance system, electronic capture system, and speed measuring radar along the highway in remote areas need to solve the problem of power supply. If low-voltage transmission lines are used for transmission, the line terminal voltage will be seriously lower than the standard value due to the long line and excessive line loss. It cannot be used; when solving the power supply problem of the aforementioned devices, distributed photovoltaic power generation has an irreplaceable advantage. It can avoid the problem of long-distance, low-voltage, and small-load power transmission. Using distributed photovoltaic power generation can not only effectively save high-speed roads in remote areas. The input cost of setting up the power grid...
