Problems solved by technology

As a kind of active management strategy, network reconfiguration is rarely considered in ADN expansion planning, mainly because distribution network reconfiguration itself is a complex mixed integer nonlinear programming problem, coupled with expansion planning, the solution of the overall model become quite complicated

Abstract

The invention relates to an active power distribution network planning method based on network reconfiguration. The method comprises the steps of (1) establishing an active power distribution network planning model based on network reconfiguration, including an objective function and a constraint function, the objective function taking the minimum social total cost overall expense as an objective, and the constraint functions including an installation constraint, a network operation security constraint and an active management constraint; and (2) transforming the power network planning model into a second-order conic programming form and performing optimization solving to obtain a power network planning scheme. Compared with the prior art, the method of the invention regards the network reconfiguration as an extended plan with zero line investment cost and considers all the lines as to-be-built lines in the network reconfiguration process, and the network reconfiguration can bring a decrease in the overall cost without an increase the investment in the power distribution network.

Description

technical field [0001] The invention relates to an active distribution network planning method, in particular to an active distribution network planning method based on network reconstruction. Background technique [0002] The traditional closed-loop design and open-loop operation of the power distribution network generally do not control the power distribution network when there is no failure; dealing with uncertainties such as power supply and load usually depends on the reserve capacity of the power supply and flexible network structure. Adopt relatively simple operation mode and control method. Therefore, traditional distribution network (traditional distribution network, TDN) planning will inevitably result in lower equipment utilization hours, and distribution network assets cannot be fully utilized. In order to improve the utilization rate of distribution network equipment and reduce the investment cost of distribution network planning, it is necessary to consider ac...
