Distributed grid voltage stability control method, device, device and storage medium

Abstract

The invention discloses a voltage stability control method of a distributed power network, which can comprehensively utilize the load growth speed at the position of each voltage stability controllerto determine the load margin value of each voltage stability controller, and then utilizes the load margin value and the voltage stability controller to carry out stability control on the distributedpower network. On the one hand, the load growth of each voltage stability controller in the whole distributed power system is considered comprehensively. On the other hand, the voltage stability controllers are coordinated effectively. It ensures the stability of voltage control of the distributed power system and the stable operation of the whole distributed power system. In addition, the invention also discloses a distributed power network voltage stability control device, a device and a storage medium, and the effect is as above.

Description

Technical field [0001] The invention relates to the field of power grids, in particular to a distributed power grid voltage stability control method, device, equipment and storage medium. Background technique [0002] With the continuous advancement of science and technology, the coupling degree of my country's power grid is becoming tighter, and the operation mode of the power grid is becoming more and more complicated. The stability of the distributed power grid voltage is the core of ensuring the dispatching operation of the power grid. Therefore, controlling the distributed grid voltage to be in a stable state is an important condition to ensure the normal operation of grid dispatching. [0003] At present, the traditional distributed grid voltage stability control method is that each voltage stability controller in the distributed grid executes control commands according to its own state to control the voltage of the distributed grid, but using this method, each voltage stabil...

Problems solved by technology

[0003] At present, in the traditional distributed grid voltage stability control method, each voltage stability controller in the distributed grid executes control commands according to its own state to control the voltage of the distributed grid. However, with this method, each voltage stability controller The controllers execute their own control instructions. On the one hand, they only control the voltage at their respective positions in the power grid, without comprehensive consideration of the overall situation of the entire distributed power grid.

On the other hand, there is a lack of effective coordination between voltage stability controllers, and information sharing and mutual restraint between voltage stability controllers cannot be carried out.

In this way, the stability of the distributed grid voltage control cannot be guaranteed, and the stable operation of the entire distributed grid cannot be guaranteed.
