Abstract

The invention relates to a robust equivalent modeling method of electrolytic aluminum and a self-provided generator set for power system control, and belongs to the technical field of power system running and control. The method comprises the following steps of firstly, modeling a self-provided generator set running constraint and an electrolytic aluminum device constraint in a high energy-loaded enterprise containing an electrolytic aluminum device and the self-provided generator set; secondly, modeling a parameter variable of a high energy-loaded enterprise equivalent model, and further modeling an exchange power constraint of the equivalent model; and finally, forming a two-stage robust optimization model for figuring out the parameter variable of the equivalent model of the high energy-loaded enterprise containing the electrolytic aluminum device and the self-provided generator set, and figuring out by using an improved column generation method. By the method, the problem of privacy protection when the high energy-loaded enterprise containing the electrolytic aluminum device and the self-provided generator set participates in power system dispatching and absorbs new energy is solved, and a foundation is provided for the high energy-loaded enterprise containing the electrolytic aluminum device and the self-provided generator set to participate in new energy absorption.

Description

technical field [0001] The invention relates to a robust equivalent modeling method for electrolytic aluminum and a self-contained unit used for power system control, and belongs to the technical field of power system operation and control. Background technique [0002] In recent years, with the continuous growth of new energy installed capacity and the construction of new energy power generation bases, serious problems of wind and light abandonment have emerged in Gansu and other regions with rich installed capacity of new energy power generation. The main cause of this problem is insufficient spinning reserve in the power system caused by insufficient local load. Due to the support of national policies, high-energy-carrying industrial parks have been built in Gansu and other areas with rich installed capacity of new energy power generation. The electricity load has a certain ability to adjust. If it participates in the power system dispatching, it can improve the level of...
