Abstract

The invention discloses an active power distribution network reconstruction method considering active management measures and demand response. An active power distribution network reconstruction model considering the active management measures and the demand response at the same time is constructed, and a corresponding solving strategy is provided. The method comprises the following steps of: firstly, establishing a power distribution network reconstruction model of active management measures and demand response by taking the minimum comprehensive cost of considering the network loss cost, the wind and light abandoning cost and the switch operation punishment cost as a target; then, aiming at the non-convexity of the power distribution network reconstruction model, introducing an intermediate variable, performing second-order cone relaxation on the intermediate variable, and constructing a mixed integer convex programming model, so that the solution efficiency can be improved while a global optimal solution is obtained; and finally, performing example simulation by adopting an improved IEEE 33-node active power distribution network. Example results show that the active power distribution network reconstruction method provided by the invention can effectively improve the clean energy consumption capability, shift the load peak-valley difference and improve the operation economy, and can provide technical support for fault recovery of the active power distribution network.

Description

technical field [0001] The invention relates to an active distribution network reconfiguration method, in particular to an active distribution network reconfiguration method considering active management measures and demand response. Background technique [0002] With the large-scale access of distributed generation (DG), the fluctuation of load and DG output makes the operation status of distribution network more complex and changeable. Using the flexible and variable network structure of the active distribution network to dynamically adjust the topology structure of the distribution network for dynamic network reconfiguration according to the results of different island divisions in each period is of great importance for improving the fault recovery level of the active distribution network and optimizing the power flow distribution of the system. significance. [0003] The network reconfiguration of active distribution network can be divided into static network reconfigur...
