Title:
REGIONAL COORDINATION CONTROL METHOD AND APPARATUS FOR VOLTAGE OF POWER DISTRIBUTION NETWORK, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/057457
Kind Code:
A1
Abstract:
A regional coordination control method and apparatus for the voltage of a power distribution network, and an electronic device. The method comprises: initializing a target power distribution network control system offline, and establishing a multistep prediction state-space model for a target power distribution network; if it is detected that the target power distribution network has a disturbance exceeding a set standard, correcting the multistep prediction state-space model on the basis of a power distribution network synchronous measurement apparatus and by means of performing state estimation and topology identification on the target power distribution network, so as to acquire a target multistep prediction state-space model; and calculating a control command sequence by using the target multistep prediction state-space model, and if it is determined that the target power distribution network achieves a closed-loop stabilization state, issuing a first step in the control command sequence as a control command, so as to realize regional coordination voltage control of the target power distribution network. Therefore, quick regional coordination control of the voltage of a power distribution network can be realized, and the problem of a voltage magnitude exceeding a limit caused by quick, dramatic and frequent fluctuations of the voltage of the power distribution network is solved.
