Regulation Technology of Air-conditioning Load in Commercial Buildings for Balance of Power Grid Peak and Valley

Recently,the rapid growth of air-conditioning load has become the main cause of seasonal power shortage.And some cities have exceeded the peak load by more than 30%.Further widening of peak-valley difference will have a serious impact on safe and stable power operation.Based on good controllability of air-conditioning load in commercial buildings,research on peak-valley balance is launched,the controllable load capacity method of multi-source information online evaluation put forward,as is the load control strategy of grid generation method based on grid interaction and load characteristics,the evaluation system facing the demand of power grid load regulation and the closed loop load regulation control method based on multiple information real-time feedback.With these technologies,the air-conditioning load control system for commercial buildings has been developed and the functions of electricity monitoring,generation and execution of control strategies and evaluation of regulation realized.Through pilot applications,the feasibility of air-conditioning load regulation technology for commercial buildings has been verified,which provides theoretical and practical guidance for the popularization and application of air-conditioning load regulation.
