摘要：

Aiming at the problems of unbalanced load diffusion and large fluctuation of load rate in single and double ring distribution network, a hierarchical load reorganization method considering closing constraint is proposed based on the special structure of single and double ring distribution network. First, a two-layer topology model of the main ring network and the branch network is established based on the internal structure of the switchyard and the simplified model of the single and double ring distribution network. Secondly, a load optimization reorganization of switchyard bus load model is proposed in the main ring network layer, with the goal of minimizing the load balance evaluation index, comprehensively considering factors such as load balance, peak load decline, etc. among them, during the operation of the bus load reorganization program, a closed loop current verification model under multiple scenarios is proposed to meet the safety operation constraints of distribution network. On this basis, a load reorganization of branch line load model is proposed in the branch line network layer to further improve the degree of load balance; Finally, taking the actual distribution network load balance of a city in East China as an example, the effectiveness and practicability of the proposed method is verified by comparing the calculation result of the traditional reconstruction method and carrying out the benefit analysis of the load reconfiguration. © 2022 Power System Technology Press.
