The local communication based distributed economic dispatch algorithm on active distribution network can effectively guarantee the economic and safe operation of distributed generation. The optimization of weighting parameters for local communication network is helpful to improve the performance of distributed scheduling algorithm. Based on the analysis of factors affecting the performance of distributed algorithms, this paper presents a mathematical programming model for topology optimization of distributed scheduling communication. This model is aimed to minimize the second largest eigenvalue of the adjacency matrix of communication network and transform communication topology optimization into semi-definite programming problem. The effectiveness of the proposed method was verified by examples.
