摘要

To reduce storage costs and improve coordination among source, load, and storage, this paper proposes a bi-level optimization strategy for distributed generation and energy storage planning. The upper level minimizes planning cost and determines siting and sizing using an SVM-based classification model. The lower level minimizes operational cost and improves voltage stability under system constraints. A quantum adaptive particle swarm optimization algorithm solves the model. Simulations on a 33-bus system verify its cost-effectiveness and stability improvement.
