Embodiment Construction

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of this application.

[0038] As recorded in the related art, when the power grid is disturbed and the voltage is unstable, a power shortage is likely to occur, and if the power shortage is too large, the wind power cannot be connected to the grid. Even if it is connected to the grid, it will cause the wind power system to abandon part of the wind power or require a large amount of thermal power rotating reserve capacity to make up for the lack of power. And at this time, if the ser...

Abstract

The invention discloses a voltage regulating method, device and equipment of a wind power energy storage combined system and a storage medium, and aims to compensate for power vacancy by adding an energy storage group, so that an output power curve of a grid-connected bus is stable, stable grid-connected operation of a wind turbine generator is more facilitated, and meanwhile, dependence on spinning reserve capacity is reduced. The method specifically comprises the steps of determining whether the wind turbine generator is in a power shortage state or not by obtaining reactive power data output by the wind turbine generator; and when the wind turbine generator is in a power shortage state, determining to-be-compensated reactive power data of the wind turbine generator according to the reactive power data, and controlling the energy storage group to perform reactive compensation on the wind turbine generator so as to perform voltage regulation on the wind power energy storage combined system. Therefore, reactive compensation of the energy storage group to the wind turbine generator is realized, and the stability of grid-connected operation of the wind turbine generator is ensured.

Description

technical field [0001] The present application relates to the technical field of power grid energy storage optimization, and in particular, to a voltage regulation method, device, equipment and storage medium for a combined wind power energy storage system. Background technique [0002] With the rapid development of offshore wind power, the proportion of wind power in the power supply is increasing. In view of the randomness and fluctuation of the output of wind power generation, the complexity of power balance and stability control of the power grid is increased to a certain extent, resulting in a decrease in the reliability of the power grid system. [0003] At present, when the power grid is disturbed and the voltage is unstable, power shortages are likely to occur, and if the power shortages are too large, the wind power cannot be connected to the grid. Even if it is connected to the grid, it will cause the wind power system to abandon part of the wind power or require ...
