Research on Large-scale Distributed Energy Cluster Control Technology

Driven by the goal of carbon peaking and carbon neutralization, the development of green energy has experienced a blowout growth. The problems such as reverse power flow and voltage quality of distribution network caused by the grid connection of a large number of distributed energy have brought many challenges to the safe and stable operation of large power grid, which has seriously affected and limited the development of distributed energy. In order to solve the problems of economic consumption and efficient utilization of a large-scale distributed energy and reduce the negative impact of large-scale distributed energy connection to power grid, this paper analyzes and studies the cluster control technology of large-scale distributed energy. Firstly, it analyzes the problems and challenges faced by large-scale power grid, distribution network, energy aggregators and power load terminal under the large-scale grid connection of distributed energy; Secondly, according to the different control demands of power grid companies and energy aggregators, different distributed energy cluster control solutions are given. The solutions deeply analyze the Data Acquisition scheme, control architecture and cluster division principle of cluster control, then introduce the application case of Xiangtan distributed energy management and control project. Finally the paper summarize and point out the development direction of cluster control system in the future.
