An incremental multi-objective hierarchical dynamic reactive power control method for regional power grid

Abstract

The invention relates to an electric engineering technology, in particular to an incremental multitarget layering dynamic reactive power control method for a regional power grid. In the incremental multitarget layering dynamic reactive power control method for the regional power grid, acquisition, analysis, calculation and control of data are finished by using a reactive power control data interaction module, an increment control module which considers load fluctuation, a multitarget layering reactive power control strategy generation module and an emergency response strategy module. By usingthe powerful data acquisition and management capability of a regional power grid energy management system of a power system, the required data is directly read from the regional power grid energy management system; and by using the conventional system, hardware investment is saved; an incremental reactive power control scheme can effectively adapt to an actual transformation situation of network load; and a layering strategy generation mechanism can effectively simplify the calculation complexity.

Description

technical field [0001] The invention relates to electrical engineering technology, in particular to an incremental multi-objective layered dynamic reactive power control method for a regional power grid. Background technique [0002] In the actual operation of the power system, it is one of the important tasks of the power management departments at all levels, especially the power dispatching centers at all levels, to realize the reasonable distribution of regional reactive power and the stable operation of voltage. At present, the data collection of the power control system is cumbersome, and the data management ability is poor; most of the voltage and reactive power control is based on the sampling data at a certain moment of the power grid, which is conducive to the simplification of the calculation process and the improvement of control efficiency. However, since the load is always changing, the reactive power control based on the data collected in a single time section ...
