Research on Source-Grid-Load-Storage Coordination Planning Method of Centralized-Distributed Form

Due to the climate problem caused by carbon dioxide emissions, the power industry, which accounts for a high proportion of energy activities, is gradually implementing renewable energy substitution. The following problems include the decline of power supply reliability and security, the weakening of power grid regulation capacity and the decoupling problem that may exist in active distribution network. Based on the theory of large scale system, this paper studies the distribution network structure planning method in the centralized-distributed form and the regional source-load coordination planning method considering the power probability balance. This paper also forms a source-grid-load-storage coordination planning method of the distribution network in the centralized-distributed form. Finally, this method is verified by simulation based on the actual power grid demand of a certain region in China, and compared with the traditional planning scheme, which proves the effectiveness and practicability of this method.
