Evaluation Method for Source and Load Matching in User Side Active Distribution Network

With the energy crisis and environmental problems highlighted, power users access distributed generation in the distribution network to achieve the goal of energy conservation and emission reduction, forming a user side active distribution network. However, the current active distribution network on the user side has caused source and load mismatch due to the dual fluctuation of source and load, resulting in issues such as voltage exceeding limits and power reverse transmission. Therefore, it is necessary to evaluate the source and load matching degree. However, existing evaluation methods lack the evaluation of source and load power quantity matching from the user side perspective. This article proposes a method for evaluating the source and load matching of user side active distribution networks. Firstly, an evaluation index system for source and load matching in user side active distribution networks was established from the perspectives of electricity matching and power matching; Secondly, the evaluation steps and methods for source and load matching in user side active distribution networks were proposed; Finally, the effectiveness of the proposed method in this paper is verified through numerical analysis of actual user side data.
