Multi-Objective Hierarchical Active Optimization Method for Active Distribution Networks Considering Bidirectional Coordination of Transmission and Distribution Networks
摘要
Abstract
With the increasing penetration of distributed power in distribution network,the mutual demand between transmission network and distribution network is increasing.Considering the issue of insufficient scheduling and allocation of resources to meet the regional autonomy needs in the optimization of active distribution network(ADN)within the framework of transmission and distribution networks collaboration,a multi-objective hierarchical active optimization model of ADN considering bidirectional cooperation of transmission and distribution networks is proposed.The model aims to improve the economy and safety of the overall operation of the transmission and distribution networks,with the power of the tie line as the coupling variables.The output of the thermal power units in the transmission network is adjusted through unit commitment,and the topology structure is configured with distribution network reconfiguration(DNR)as the main strategy to determine the scheduling strategy that supports the optimal opera-tion mode of the system.Based on analytical target cascading(ATC)method,the multi-objective main and sub problems of the ac-tive distribution network with bidirectional cooperation of transmission and distribution networks are decoupled and solved hierarchi-cally.Finally,the T6D2 and T118D5 test systems are taken as examples to verify the effectiveness of the proposed method.The results show that the model can deal with the phenomenon of"reciprocating flow"between transmission and distribution networks well,and improve the renewable energy consumption rate of the system,so that the transmission and distribution networks can obtain the maximum economic benefit.关键词
