Problems solved by technology

Therefore, the accident rate in the power system has also increased relatively, and the losses caused by accidents are also difficult to estimate.
Especially in the application of regional power grids, due to the slow update and inadequate protection measures of some equipment, heavy load or even overload often occurs, which reduces the safety and stability of power grid operation and brings certain problems to the maintenance of normal power supply of the power grid.

Abstract

The invention discloses an auxiliary decision-making method and device for risk control after a power grid accident and a storage medium. The method comprises the steps of: carrying out the optimal load reduction of a current monitoring power grid after an accident happens to the current monitoring power grid; recovering the power grid fault of the current monitoring power grid after load reduction based on a network reconstruction method; and for fault equipment in the current monitoring power grid, determining a risk minimization target-based transfer strategy of the current monitoring powergrid. According to the auxiliary decision-making method and device for risk control after a power grid accident and the storage medium disclosed by the embodiment of the invention, the fault recoveryefficiency of the power grid after the fault can be effectively improved, and the risk of the power grid is reduced.

Description

technical field [0001] The electric power technology of the embodiments of the present invention, in particular, relates to an auxiliary decision-making method, device and storage medium for risk control after a power grid accident. Background technique [0002] With the rapid development of social life and production, the operation and application of power systems have become more and more complex and unstable. Therefore, the accident rate in the power system has also increased relatively, and the losses caused by accidents are also difficult to estimate. Especially in the application of regional power grids, due to the slow update and inadequate protection measures of some equipment, heavy load or even overload often occurs, which reduces the safety and stability of power grid operation and brings certain problems to the maintenance of normal power supply of the power grid. Difficulties. Contents of the invention [0003] The invention provides an auxiliary decision-ma...
