Problems solved by technology

In recent years, photovoltaic-solar-thermal integrated distributed power generation systems have become the mainstream of development. A large number of distributed power generation is connected to the distribution network. The large amount is scattered, and it is difficult for the power grid to monitor it, which will affect the safety, reliability and stability of the distribution network. Operation and control have many influences
[0003] As a new type of clean energy, distributed photovoltaic power generation depends on the weather, resulting in poor stability of the power generation system. Therefore, effective real-time monitoring and management of distributed photovoltaic power generation is required
