Power grid active power safety correction method and device, electronic equipment and storage medium

Abstract

The invention provides a power grid active power safety correction method and device, electronic equipment and a storage medium. The power grid active safety correction method comprises the following steps: when a target line is overloaded, inputting state information in a power grid into a trained power grid active safety correction enhancement model, and determining a target generator set needing output adjustment in the power grid; and based on the target sensitivity of the overloaded target line to the target generator set, calculating the target output adjusting quantity of the target generator set. When multi-line overload is processed, the output of the generator set can be adjusted on the basis of the current operation state information of the power grid and the target sensitivity of the overload line to the generator set and the calculated target output adjusting quantity of the generator set, the line overload is efficiently eliminated, and the output of the generator set is improved. And the elimination effect of the load flow distribution condition and the output regulating quantity of the current power grid on the line overload is comprehensively considered.

Description

technical field [0001] The present application relates to the technical field of power grid optimization, and in particular to a power grid active power safety correction method, device, electronic equipment and storage medium. Background technique [0002] In the operation of the power system, controlling the power flow of the line within a reasonable threshold is the basic requirement to ensure the safe and stable operation of the system. Generally, the frequency deviation caused by the system load fluctuation and the power fluctuation of the tie line between the systems can be controlled by the automatic generation control. Adjustment, for the line overload caused by the change of the system operation mode due to maintenance plan, line failure and other factors, it is necessary to rearrange the output of the unit to eliminate the overload of the line to ensure the safe operation of the system. The active safety correction is mainly through the reasonable arrangement of the...

Problems solved by technology

[0003] Power grid active power safety correction methods in the prior art can be divided into two categories: optimization method and traditional sensitivity algorithm. The optimization method is to construct an optimization model by formulating the objective function and determining the safety constraints, and use the solution of mathematical programming to realize the power grid. Active power safety correction, but when the optimization method is used for power safety correction, there will be too many adjustment units involved in the adjustment of the grid regulation, and the traditional sensitivity algorithm is to eliminate the load by transferring the load of the overloaded line to other lines. purpose of overload
