Load Control Scheme of Inverter Air Conditioner Under The Influence of Multiple Response Potential Factors

The proportion of inverter air conditioner in the household air conditioner has surpassed that of the fixed-frequency air conditioner and become mainstream. To make this growing demand response resource play the role of peak-load shifting in power system, a three-layer regulation framework of inverter air conditioner was proposed to analyze and research the response potential, scheduling model, and control strategy of inverter air conditioner. At the level of potential assessment, based on the steady power of inverter air conditioner, the load aggregation power of inverter air conditioner was obtained, and considering multiple influencing factors on the user side the load aggregation response potential assessment model of inverter air conditioner was established to obtain their aggregation response potential. At the day-ahead scheduling layer, considering the potential of inverter air conditioner in each time period and combining with the response characteristics of the foundation flexible load a joint scheduling model was established, so as to tap the potential of multiple types of resources participating in the regulation on the load side. In the intra-day control layer, the dynamic and steady-state models of inverter air conditioner were analyzed, and the grouping and clustering were carried out by taking steady-state parameters and temperature-varying parameters as characteristic attributes. The temperature control method was applied to inverter air conditioner to implement the group control to make the load of inverter air conditioner follow the scheduling plan. Finally, by means of a certain distribution system, the verification analysis was conducted, and the conclusions show that the proposed three-layer regulation framework possesses a certain guiding significance for the utilization and guidance of the load response potential of inverter air conditioner.
