[0001] The invention relates to the field of photovoltaic technology, in particular to a distributed photovoltaic power station. Background Art

[0002] With the continuous development of my country's industrial industry, the contradiction between environmental protection and energy supply has become increasingly prominent. As a renewable and clean energy source, solar photovoltaic power generation has been vigorously developed. In recent years, my country's total installed capacity of photovoltaic power generation has remained the world's first. Photovoltaic power stations are divided into centralized and distributed types. Centralized power stations occupy a large area, while distributed photovoltaic power stations have developed rapidly in recent years due to their convenient grid connection and flexible site. More and more industrial and commercial factory roofs have begun to install distributed photovoltaic power stations. Distributed photovoltaic power stations usually refer to power generation systems that use distributed resources, have a small installed capacity, and are arranged near users. They are generally connected to power grids with voltage levels below 35 kV or lower. Distributed photovoltaic power stations specifically refer to distributed photovoltaic power station systems that use photovoltaic modules to directly convert solar energy into electrical energy. Since distributed photovoltaics are usually used on the user side, such as residential roofs, factories, etc., and are mainly used to power themselves, it has become a technical problem that needs to be solved in distributed photovoltaic power stations to increase the power generation as much as possible under the limited number of photovoltaic panels, and to facilitate maintenance to increase the service life.
