Central air conditioner demand response scheme optimization method based on global temperature adjustment

Abstract

The invention relates to a central air conditioner demand response scheme optimization method based on global temperature adjustment. The method comprises the following steps of 1) constructing demandresponse strategies of three types of central air conditioners, and giving a group of temperature adjustment value sequences of discretized execution time periods according to the temperature adjustment resolution of the central air conditioners; 2) for a temperature adjustment value delta TG of each discretized execution time period under each type of demand response strategy, obtaining a relational expression between the temperature adjustment value delta TG of the execution time period and the interactive power; 3) defining a user demand response net income index pi, and calculating a userdemand response net income index corresponding to the temperature adjustment value delta TG of each discretized execution time period under each type of demand response strategy; and 4) selecting anoptimal central air conditioner demand response scheme and an optimal temperature adjustment value according to the user demand response net income index. Compared with the prior art, the method has the advantages of being comprehensive and accurate, achieving net income maximization, understanding user behaviors and the like.

Description

technical field [0001] The invention relates to the field of building demand response control, in particular to a central air-conditioning demand response scheme optimization method based on global temperature adjustment. Background technique [0002] In modern society, building loads contribute more and more to the peak load of the grid. Taking my country as an example, building energy consumption has accounted for 44% of the country's total energy consumption. Among them, central air-conditioners (CAC) are the main energy-consuming equipment, which can account for more than 50% of building energy consumption. Modern buildings have good heat storage capacity, and can advance or postpone electricity consumption without affecting user comfort. Therefore, CAC can be used as an important demand-side resource to provide services such as peak shaving and valley filling to the grid.

[0003] Existing research mainly considers demand response compensation benefits, but in fact, building participation in demand response will affect human comfort. A large number of studies have shown that there is a relationship between human thermal comfort and work efficiency, and the hidden loss caused by the reduction of comfort may In this way, regardless of the loss of work efficiency, it will make an overly optimistic misjudgment of the willingness of users to participate in demand response, and it is not conducive to the power grid to formulate a reasonable demand response compensation mechanism
