Abstract

Abstract: The market shares of the inverter air conditioners (ACs) have increased in recent years due to their high energy efficiency ratio. The inverter ACs have great potentialities of participation in the demand response programs in power systems. This article proposes an evaluation method of the aggregated power and the response potential for aggregated inverter AC loads with the consideration of load heterogeneities. The clustering algorithm is firstly used to group the inverter ACs according to their daily load profiles. The individual geometrical polytope is adopted to model the response potential of each individual inverter AC. And then the response potentialities of other inverter ACs are replaced by the isomorphism of the given convex polytope. Finally, the aggregated response potential of the inverter ACs is obtained with the Minkowski summation algorithm. The simulation results prove that the proposed method has a better estimation accuracy of the aggregated response potential, and the maximum potential of each inverter AC is better utilized. Abstract : A clustering algorithm is applied for the inverter ACs with considerations of the load heterogeneities and then establishes the response potential models of each cluster group, which can improve the evaluation accuracy of the response potential.
