Modeling and Control of Central Air Conditioning Loads for Peak Shaving

摘要

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.
