Abstract

The invention provides a hybrid control method and system for a power spring, equipment and a storage medium, and the method comprises the steps: obtaining the data of the power spring, substituting the data into a preset analysis model, obtaining a system basic strategy of the analysis model, and obtaining the operation data of the analysis model based on the system basic strategy, wherein the analysis model comprises analysis constraint conditions; constructing a data driving model based on the operation data and an extreme learning machine method, wherein the data driving model comprises data driving constraint conditions; replacing the analysis constraint conditions in the analysis model with a data-driven constraint condition to obtain a hybrid model, and obtaining a hybrid control strategy of the power spring based on the hybrid model; and obtaining hybrid operation data based on the hybrid control strategy of the power spring, and selecting the analysis model or the data drivingmodel according to the hybrid operation data. According to the method, the pressure regulating effect of the power spring under the condition that system parameters cannot be accurately obtained is improved.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a hybrid control method, system, equipment and storage medium of electric springs. Background technique [0002] Due to the intermittency and uncertainty of renewable energy, voltage regulation in distribution networks with high penetration of renewable energy is a challenging problem. Traditional voltage regulation devices, such as on-load tap changer (LTC) and capacitor bank (CB), can only control voltage in a discrete manner, and the control frequency is low, which cannot effectively deal with the voltage fluctuation problem caused by renewable energy generation , in order to improve the coordinated control of electric springs and traditional equipment, it is necessary to study related control methods. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the problems of the prior art, the present invention prop...
