Comprehensive energy system demand response method based on dynamic process optimization

Abstract

The invention relates to a comprehensive energy system demand response method based on dynamic process optimization, which is based on a brand-new design architecture, takes electric charge as a mainfactor, introduces three factors of power purchase cost in the production period of a power plant, transition cost corresponding to transition between different power generation operation modes and inventory cost of an energy storage unit, and jointly participates in application. A power supply objective function is constructed, and more efficient power supply scheme selection is provided for a power plant; the design method has the characteristics of comprehensiveness, independence, easy measurement, flexibility and practicability, required data sources are convenient and easy to understand,and meanwhile, due to the fact that the proposed optimization formula is easier to process and a pre-calculated transition curve is used, the non-convexity of the basic optimization formula can be reduced, and the reliability of the design method is improved. The optimization problem can be solved more easily, and the response efficiency of the actual work of the power plant is improved.

Description

technical field [0001] The invention relates to a demand response method for a comprehensive energy system based on dynamic process optimization, and belongs to the technical field of power supply response. Background technique [0002] Demand response has been the subject of significant research, development and deployment over the past few years. Energy demand management is an important task in industrial process systems to realize potential benefits by facilitating the interaction and response of process operations. However, in this task, the dynamic behavior of the underlying process, especially transition trajectories, is rarely considered. Furthermore, energy constraints related to electricity pricing and supply are one of the key challenges in this process. [0003] Demand-side activities have been at the center of attention in all energy policy decisions in recent years due to the large economic and operational gains that can be realized through demand-side managem...
