Hierarchical and Divisional Optimal Dispatching Strategy for Active Distribution Network based on Hybrid Particle Swarm Optimization

Randomness and uncertainty of the intermittent renewable energy introduces great challenge on energy management of distribution network, the active distribution network is an important technical to achieve plenty of renewable energy fully consumed, as well as other controllable resources. This paper describes a hierarchical and divisional framework of multi-source coordinated interactive dispatch for active distribution network. In the framework, a local optimization control algorithm of regional distribution network and a global optimization control strategy for active distribution network are proposed. The strategy maximizes the utilization of clean energy and utilizes the renewable energy locally meanwhile guaranteeing stable and optimal operation of active distribution network. Finally, the feasibility and effectiveness of the strategy proposed in this paper is verified through the numerical example.
