Abstract

The invention relates to the field of power grid regulation and control, in particular to a regulation method and a storage device for transmission line current carrying and node voltage in a wide-area measurement environment. The method for regulating the current carrying capacity and node voltage of the transmission line under the wide-area measurement environment includes the steps of: establishing an observable function of the observation point and an adjustable function of the observation point; combining the observable function, the adjustable function and the historical quantity The sensitivity control model of transmission line current and node voltage is calculated from the measured data; the key transmission line current and key voltage are calculated; the optimal control amount of key transmission line current and key voltage is selected according to the control error of the sensitivity control model, and the key transmission line The optimal control amount of line current and critical voltage is adjusted. Through the above method, the regulation and control of the aggregated grid voltage and the current of the transmission line is realized.

Description

technical field [0001] The invention relates to the field of power grid regulation, in particular to a method and a storage device for regulating the current carrying and node voltage of a transmission line in a wide-area measurement environment. Background technique [0002] The safety regulation of current and node voltage of power system transmission lines has always been the focus of research. With the implementation of energy conservation, emission reduction, and energy cleanup policies, renewable energy power generation has been continuously integrated into the power grid in the form of centralized and distributed, causing new problems in the regulation of the power system. As a result, the phenomenon of two-way flow of generated power in the power grid has exacerbated the difficulty of regulation. [0003] Fortunately, on the basis of GPS, the improvement and popularization of the Wide-Area Measurement System (WAMS) guided by the Phasor Measurement Unit (PMU) can rea...
