Abstract Driven by the national “dual carbon target” policy, the installed capacity of photovoltaic power has increased rapidly, reaching 890million kilowatts by the end of 2024. In Jiangsu, Shandong, Henan and other regions of China, the photovoltaic power generation of distribution system has exceeded the local load demand during peak hours, showing a new feature of reverse transmission of electric energy from the distribution network to the main network. Different from the traditional distribution system, the strong uncertainty of photovoltaic power source makes the operation state of distribution system change in a wide range, and the conventional current protection is difficult to trip quickly and accurately.
