Abstract

The invention proposes a uncertainty based reconstruction method for an active power distribution grid. The method comprises the following steps of: building a multi-target reconstruction mode with minimum grid loss and cost; processing a load parameter of the mode by using an interval analytic hierarchy process; and acquiring the optimal solution of the multi-target reconstruction mode by combining a binary particle swarm optimization with a harmony search algorithm containing a distribution grid (DG), wherein the optimal solution comprises a switch state, and the position and the output power of the DG.

Description

technical field [0001] The invention relates to a reconfiguration method, in particular to an uncertainty-based active distribution network reconfiguration method. Background technique [0002] Network reconfiguration is a process of switching and adjusting the disconnection status of tie switches and section switches in the network. Through network reconstruction, the new topology network can reduce network loss and improve operational reliability. [0003] During the reconstruction process, timing influence and environmental factors will inevitably lead to data uncertainty. These uncertainties are usually manifested as load fluctuations, fluctuations in equipment maintenance parameters, and so on. Taking load uncertainty as an example, in load forecasting, it is often necessary to use an uncertain value range to describe the load in a certain period of time in the future. Such a value is more loaded with objective requirements. The prediction results obtained by using ...
