Abstract

The invention discloses a two-stage robust planning method for a flexible multi-state switch and related equipment. The present invention determines the maximum number of connected flexible multi-state switches in the distribution network according to the coverage area of ​​the active distribution network to be connected to the flexible multi-state switch and the maximum power supply coverage area of ​​a single flexible multi-state switch; According to the number of feeders in the distribution network and the maximum number of flexible multi-state switches to determine the combination scheme of the number of access ports of the feeder, combined with the comprehensive sensitivity of the two-level planning method to the node and the laying direction of the connecting cable in the road network, Determine the access node and mounting location for each flexible multi-state switch. Finally, according to the uncertainty of new energy power generation output and load output, the two-order robust model of the capacity of the flexible multi-state switch in each port number combination scheme is optimized and solved. The technical scheme of the invention improves the power regulation capability and practicability of the flexible multi-state switch.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a two-stage robust planning method for a flexible multi-state switch and related equipment. Background technique [0002] As the penetration rate of new energy power generation in the distribution network continues to increase, the common wind power generation and photovoltaic power generation are greatly affected by the weather, and their output shows volatility and uncertainty. The traditional distribution network is difficult to deal with such challenges effectively due to its few regulation methods and slow response speed. Therefore, the traditional distribution network has gradually developed into an active distribution network including flexible multi-state switches, energy storage devices, reactive power compensation devices and other active control equipment. At present, the configuration planning of flexible multi-state switches mainly focuses on the planning ...
