Distribution network planning method for source-network-storage collaboration

This article introduces a distribution network planning method for source network storage collaboration. This method is based on the principle of minimizing power grid investment and operating costs, and improves the economy and reliability of the collaborative system through collaborative optimization of source, network, and storage. Specifically, this article proposes two optimization models: the source network storage collaborative optimization model and the storage device selection optimization model, and solves these models using genetic algorithms and other methods. In addition, this article also proposes two distribution network planning schemes based on microgrids and multi energy storage systems, and conducts simulation analysis on the IEEE-33 node testing system. The results show that compared with traditional methods, the source network storage collaborative optimization method proposed in this paper has significant advantages in multiple aspects such as comprehensive economy, power grid stability, safety, and environmental protection. Therefore, this method provides an innovative approach and method for the field of distribution network planning, which can provide reference for dispatch departments and promote more optimized distribution network planning.
