Abstract

This paper proposes a source-load-storage hierarchical coordinated planning control strategy for distribution network based on cluster partitioning. Firstly, a comprehensive index-based cluster partition method for distribution network considering electrical distance under load forecasting is proposed. Secondly, on the basis of cluster partitioning, a bi-level joint planning model is proposed. The upper layer establishes a source and storage location and capacity model for the uncertainties of the internal source and load of the cluster. The lower layer takes the minimum node voltage deviation as the objective function, and establishes a voltage control model involving Markov decision processes. Then, the particle swarm optimization algorithm of annealing strategy and the gradient algorithm of deep deterministic strategy are used to solve the upper and lower models, which improves the resilience of the renewable energy distribution network and realizes the coordinated planning control of the different spatial responses of the source-load-storage of the distribution network. Finally, the effectiveness of the source-load-storage bi-level optimization model is verified in an actual 35 kV/10 kV distribution network.
