Access planning method for industrial large users based on access risk

In the environment of high speed development of large user industries, in order to ensure safe and reliable access to the grid for industrial large users, this paper proposes an industrial large user access planning model based on access risk. First, the traditional economic and security indicators are replaced by risk indicators, and the risk indicator system is constructed by considering the uncertainty of large user access capacity. Then, the CRITIC method is used to assign weights to the indicators of comprehensive risk, and the artificial bee colony algorithm is used to find the optimal access node as the target, so as to complete the site selection and access work of industrial large users. Finally, the effectiveness of the proposed method is verified by using the IEEE-69 node system as an example.
