Research on Solution Generation and Economic Analysis of Distributed Power Considering the Dispersion of Access Location

With the continuous advancement of 'carbon peak and carbon neutrality' strategy, the proportion of distributed generation integrated into the distribution network has rapidly increased. This paper examines the schemes for integrating high-proportion distributed generation into the distribution network, with a focus on analyzing the impact of the degree of distribution of distributed generation on the network. Firstly, this paper introduces the classification of distributed generation and the current state of distributed energy development in China. Secondly, an optimization method for integrating distributed photovoltaic based on sensitivity ranking is proposed. This method quickly adjusts PV output by calculating the sensitivity matrix of line power to node injection power to meet grid technical requirements. Finally, using the actual grid of a city as a case study, different integration schemes for distributed PV under varying levels of dispersion are analyzed, and the technical and economic performance of centralized and decentralized integration schemes is compared. The conclusion is that the greater the degree of dispersion in high-proportion distributed PV integration, the larger the maximum PV capacity that can be integrated, and the economic benefits of decentralized integration of high-proportion distributed PV into the distribution network are greater than those of centralized integration.
