Active Distribution Network Reconfiguration Method to Promote Distributed Energy Consumption

Abstract

The present invention proposes an active distribution network reconfiguration method that promotes the consumption of distributed energy, including determining the optimal compensation energy and position of the capacitor by using the improved leapfrog algorithm, simplifying the distribution network, and adopting tree-like layering , using breadth-first search to judge the radioactivity of the network to make the switch open and close sequentially, and optimize the objective function through binary genetic algorithm. This method can promote the consumption of distributed energy by optimizing the location and capacity of the capacitor when it is connected to the grid, which can reduce the waste of clean energy, and can reduce the number of reconfigurations during the reconfiguration process, reducing the failures and reduce operating costs. The combination of tree structure and layering can make the layers clear, and through the breadth search, it can reduce the infeasible solutions in the reconstruction and speed up the convergence speed of the algorithm.

Description

technical field [0001] The invention relates to power distribution technology, in particular to an active distribution network reconfiguration method for promoting the consumption of distributed energy. Background technique [0002] Distribution networks have a ring structure, but usually operate in an open loop. The distribution network contains a large number of section switches (normally closed, used to isolate faulty parts) and a small number of contact switches (normally open, used to provide optional power supply paths), so under normal operating conditions, it can be used according to different load conditions. , Change the on / off state of these switches to adjust the network structure, on the one hand, reduce the network loss, on the other hand, make the load as evenly distributed as possible among the lines and transformers. Distribution network reconfiguration is an important means to improve the economy, power supply quality and security of power grid operation. ...
