摘要

中央空调负荷所占比重大,且具有蓄热特性,可通过适当控制来实现调峰。通过分析单机中央空调的工作原理,建立了单机中央空调的简化模型。在个体模型的基础上,提出了中央空调负荷参与调峰的最优控制模型。目标是获得最大的调峰负荷。约束考虑了调峰和用户的舒适度。需要注意的是,该优化模型是一个混合整数线性规划,求解方便。基于中央空调测试平台,可以验证个别模型的正确性。仿真结果验证了该最优调峰控制模型的有效性。

Modeling and Control of Central Air Conditioning Loads for Peak Shaving
Peak shaving can be realized by applying appropriate control on central air conditioning loads due to their large proportion and thermal energy storage characteristics. Simplified model of single central air conditioner is established by analyzing its operating principle. Based on individual model, optimal control model of central air conditioning loads for participating in peak shaving is proposed. Objective is to obtain maximum loads of peak shaving. Constraints take peak shaving and users’ comforts into consideration. It should be noted that this optimization model is a mixed integer linear programming and can be solved conveniently. Based on the test platform for central air conditioner, the correctness of individual model can be verified. The effectiveness of optimal control model for peak shaving is verified by simulation results.
