Problems solved by technology

The power grid is composed of several aggregated grids, and each aggregated grid can achieve its own independent regulation, but from the perspective of the grid, the regulation cannot reach the global optimum, because the renewable energy generation in each aggregated grid has volatility and Intermittent characteristics, when the output power of renewable energy generation in an aggregated grid is large, it can be provided to other aggregated grids in addition to meeting local needs; but when the output power of renewable energy generation in an aggregated grid is less, it Renewable energy generation or economical generator sets from other aggregated grids are needed to support

Abstract

The invention discloses an active power security correction method of considering coordination among multiple polymers. A correlation coordination relation between control functions among multiple polymer grids is researched in the aspect of active power security correction on the basis of forming observation point observation functions of the polymer grids. Selection of control nodes is carried out through the comprehensive sensitivity and output increasing nodes and output reducing nodes are determined; an active power security correction model of considering the control cost is built; whenactive power of a power transmission line among the polymer grids is overloaded, the power of an overload branch is quickly and effectively reduced and the overload is eliminated through coordinationof the observation point control functions at two ends of a power transmission section, and meanwhile, the condition that a normal branch and the corrected branch are not overloaded is ensured.

Description

technical field [0001] The invention relates to an active safety correction method considering coordination among multipolymers. Background technique [0002] Power generation and power consumption change periodically over time, which causes the active power of transmission components to change. Whether the active power level of power transmission components meets the requirements requires real-time monitoring and regulation according to operating requirements. Today, the continuous advancement and implementation of energy conservation, emission reduction, and energy cleanliness policies have prompted renewable energy power generation to be continuously integrated into the grid in a centralized and distributed manner, causing new problems in this monitoring, especially regulation; at the same time, in the largest Driven by the policy of eliminating renewable energy power generation, the phenomenon of "two-way flow" of power generation in the power grid has aggravated the dif...
