A regional hierarchical energy storage planning method based on improved particle swarm optimization
Large-scale renewable energy bases are being constructed in Northwest China. To promote regional renewable energy integration
this paper proposes a regional hierarchical energy storage planning method based on an improved particle swarm optimization (IPSO) algorithm. First
the initial solution for energy storage planning is obtained through the typical day method via scenario generation and used as the input for the IPSO algorithm. Then
a bi-level energy storage planning is carried out based on the IPSO algorithm to derive the optimal solution: the upper level adopts a provincial-municipal-unit hierarchical planning framework
while the lower level performs production simulation. Finally
the feasibility and effectiveness of the proposed method are verified through a case study of a certain province in China. The results indicate that the proposed method can significantly enhance renewable energy integration capacity and improve overall system economics.
