The application occasions of distributed photovoltaic power generation system can be divided into two categories:
First, it can be popularized on all kinds of buildings and public facilities in the country to form a distributed building photovoltaic power generation system, which can be established by using all kinds of local buildings and public facilities to meet the partial power demand of power users and provide production power for high energy consuming enterprises.
Second, it can be popularized in remote areas such as islands and other areas with low power and no electricity, forming off grid power generation system or micro grid. Due to the gap in economic development level, there are still some people in remote areas in China who have not solved the basic power consumption problem. In the past, most of rural power grid projects rely on the extension of large power grid, small hydropower, small thermal power and other power supply, so it is very difficult to extend the power grid, and the power supply radius is too long As a result, the quality of power supply is poor. The development of off grid distributed generation can not only solve the basic power consumption problem of residents in the areas with low power consumption, but also make clean and efficient use of local renewable energy, effectively solving the Mao Dun between energy and environment.
