Method and device for constructing multi-period high-dimensional projection unit combination model

Abstract

The invention is applicable to the technical field of electric power, and provides a method and device for constructing a multi-period high-dimensional projection unit combination model, and the method comprises the steps: projecting a unit power variable and related parameters to an interval [0, 1] by collecting the basic data of a motor unit of an electric power system and employing a variable projection technology; introducing all running states of a single unit of the motor unit in a plurality of time periods, and systematically deriving an ideal expression form of unit output upper boundconstraints and climbing constraints in the plurality of time periods by utilizing the introduced state variables on the basis of actual running requirements of the unit; eliminating the new state variable by utilizing the relationship between the introduced new state variable and other state variables so as to improve the conciseness of the model, and finally obtaining a multi-period unit combination model after other constraints and target functions are added. According to the modeling method, a multi-period high-dimensional projection unit combination model is established. The model is morecompact, and the calculation efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method and a device for constructing a combination model of a multi-period high-dimensional projector unit. Background technique [0002] Energy is the blood of modern society and an important material basis for the survival and development of human society. However, the massive consumption of fossil energy has also led to more serious problems such as energy shortage and environmental pollution. As an important form of energy consumption in my country's social production and life, electric energy occupies a large proportion in the total energy consumption. However, since thermal power generation consumes a large amount of fossil energy and produces a large amount of greenhouse gases such as carbon dioxide, the power industry has become a major "consumer" of fossil energy and a major "producer" of greenhouse gases. In this context, using renewable energy to repl...
