The Research of Control Strategy Based on Hierarchical Consistency Algorithm in Active Distribution Network

With the increase of renewable energy in distribution network, development of active distribution network adapt to the control and management of distributed generation. In order to adapt to the increase of distributed generation which makes the distribution network expansion planning more complex, This paper presents an active control method of hierarchical consistency to control distributed generation when the load changes. Each control objectives need to interact with the neighboring targets, and it can achieve the goal of global optimal control without global information. The method classifies the distributed generation node, and achieves the ultimate goal of consistency based on the information communication of local distributed generation by monitoring the power of main distributed generation node and other distributed generation nodes in each layer. The efficiency and feasibility of the strategy are demonstrated by IEEE26 system.
