A novel aggregated modeling method of air conditioning loads

Air conditionings (ACs) as a typical demand response (DR) resource play an important role in providing ancillary service for the grid. The detailed modeling process of the aggregated model of ACs is given firstly and it comes a conclusion that the previous models can't track the dynamic behaviors of ACs when the dispatch period becomes longer. In order to improve the modeling accuracy at longer dispatch period, we focus on a novel aggregated model of homogeneous ACs with higher accuracy to describe their operating behaviors with time, which makes the operating performances fully taken into account; the detailed derivation of the aggregated model is also given. Simulation results demonstrate that the proposed aggregated model has a higher accuracy compared with previous models and can be applied in more ancillary services.
