Abstract

The embodiment of the invention discloses a power grid regulation and control method and device. The power grid regulation and control method comprises the steps of obtaining operation conditions of a power grid; performing current detection on the operation condition to determine whether the power grid is overloaded or not; when the power grid is overloaded, performing regulation and control simulation on the power grid according to a preset logic rule, and determining whether the power grid after regulation and control simulation is still overloaded or not; if the power grid is still overloaded, determining an executable operation according to a preset strategy network, and determining whether the power grid subjected to the executable operation is still overloaded or not; if the power grid subjected to the executable operation is not overloaded, the optimal operation in the executable operation is executed, and if a preset alarm condition is met at the current moment, an alarm prompt is given out. According to the power grid regulation and control method and device provided by the embodiment of the invention, the long-time stable control capability of a power grid regulation and control system under a large-scale complex uncertain working condition and the early warning capability under an emergency condition can be improved, so that the reliability of power grid operation is guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to power grid regulation technology, and in particular, to a power grid regulation method and device. Background technique [0002] The power grid control system integrates data acquisition, storage, analysis, decision-making and control, and runs through multiple links such as power generation, transmission, distribution, and use, and has been widely used in the control tasks of large-scale power grids. However, the current power grid control system is still mainly based on equipment monitoring and manual analysis, in which decision-making, execution and other aspects still require the participation of control personnel with expert knowledge, and more rely on the experience analysis of the control personnel. With the continuous expansion of the power grid scale in recent years, the traditional human-based power grid control system is obviously unable to meet the increasingly complex power grid control needs....
