Control strategy making central air conditioner load group participate in peak regulation of electric power system

Abstract

The invention discloses a control strategy making a central air conditioner (CAC) load group participate in peak regulation of an electric power system. According to the control strategy, a central air conditioner monomer load model used for participating in peak regulation of the electric power system is provided, host electro-thermal conversion, a chilled water heating process, fan coil heat exchange and a tail end room space heat model are included, and the accuracy of the proposed model is verified through a test platform. According to the control strategy, the system architecture that thecentral air-conditioning load group participates in the peak regulation of the power system is constructed, the optimization model that the central air-conditioning load group participates in the peak regulation of the power system is provided, and piecewise linearization is carried out on nonlinear constraints, so that the model is convenient, quick and effective to solve. According to the control strategy, he peak regulation capacity of the power system can be improved by controlling the central air conditioner; the comfort of a user is fully considered; the influence on central air conditioning equipment is very small; the requirement on the real-time performance of communication is not harsh; and the established mathematical optimization model is a mixed integer linear programming, and therefore a common mathematical optimization solver can be conveniently used for rapid and effective solving.

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...
