The zoning coordination control of active distribution network takes into account the global coordination between regions and the internal optimization control of each region.However,the unbalanced power distribution method and the centralized optimization method under the reliability principle of the traditional global coordination method cannot meet the operation requirements of the current economy-oriented active distribution network.For this reason,an economic coordination control method of active distribution network based on the consistency theory was proposed.The two-level multi-agent system was used to realize the coordination between regions and the internal optimization control of each region.The intelligent agents at all levels are regarded as equivalent power sources,and the overall economic optimization was achieved through the consistent control of the micro-increment rate of power generation cost;the information interaction,optimization and control process between adjacent agents at the same level were all carried out locally in the agent.The agent optimization requires less computation and can quickly adjust its own operation status according to the changes of the distribution network.An active distribution network example of IEEE 33-bus system is used for simulation,and it is verified that the algorithm can adapt to the changes of the distribution network and quickly adjust the cost of each adjustable unit to the same rate under the condition that the power at the outlet of the main feeder is basically unchanged,so as to meet the proposed control requirements,which is of reference significance for the research of the active distribution network in the future.
