A control strategy for central air-conditioning load groups to participate in power system peak regulation

Abstract

The invention discloses a control strategy for a central air conditioner (Central Air Conditioner, CAC) load group to participate in power system peak regulation. The present invention proposes a central air-conditioning unit load model for participating in peak regulation of the power system, including the electrothermal conversion of the main engine, the thermal process of chilled water, the heat exchange of the fan coil unit, and the space thermal model of the end room, and the proposed model is verified by the test platform accuracy. The present invention constructs a system architecture in which the central air-conditioning load group participates in power system peak regulation, proposes an optimization model for the central air-conditioning load group to participate in power system peak regulation, and performs segmented linearization on nonlinear constraints, making the model convenient, fast and effective to solve. The invention can improve the peak-shaving capability of the power system by controlling the central air-conditioning; fully consider the user comfort; have little impact on the central air-conditioning equipment; do not have strict requirements on real-time communication; the built mathematical optimization model is a mixed integer linear programming, which is convenient Use common mathematical optimization solvers for fast and efficient solutions.

Description

technical field [0001] The invention relates to a control strategy for a central air conditioner (Central Air Conditioner, CAC) load group to participate in power system peak regulation. Background technique [0002] During the peak power load period in summer and winter, power shortages are prone to occur, and peak shaving is critical to the safe and stable operation of the power system. At present, the method of orderly power consumption is usually used for peak load regulation during the peak period of power load. In order to reduce the impact on people's livelihood, priority is given to orderly power consumption regulation for high energy-consuming industrial loads. In extreme weather conditions, residential load power consumption will be limited. In recent years, demand side response has been proposed to implement peak regulation of the power system to reduce the adverse effects of power rationing. [0003] Air-conditioning load is a typical demand-side response resour...
