Exploration and Practice of "Cluster Regulation" of New Active Distribution Network

There are 79 distributed power stations in Lin'an Power Supply Company. According to the terrain characteristics and distribution network situation in Lin'an, the three-step strategy of "visualization of distribution network distributed power stations", "local consumption of green energy" and "improvement of emergency response capability" is proposed to complete the goal of building a green distributed energy "cluster control" system. The "cluster control" system in the pilot Changhua River Basin and Mazhao River Basin eliminates the possible heavy load impact caused by the peak load period of power grid equipment by regulating the basin hydropower output and time. It has effectively alleviated the problem of overload of the hub transmission channel of the power grid and "blockage" of power supply equipment for centralized energy consumption by users. Improved power channel utilization. The power supply stability of the regional distribution substation area has been improved, reducing the power grid upgrading and construction costs that grid enterprises must invest due to high load in individual periods. The elastic power generation of hydropower stations can offset the concentrated power consumption period of power enterprises and smooth the power supply curve of the grid.
