Characteristic Analysis and Calculation Method of Aggregated Air Conditioning Loads Providing Reliable Reserve for Power System

Air conditioning loads have the potential to provide reserve for power system after aggregation. In order to realize the participation of aggregated air conditioning load in system scheduling and provide trusted reserve capacity, an analysis and calculation method of trusted reserve characteristics of aggregated air conditioning load was proposed. Firstly, the response time and available reserve capacity of the standby dynamic process were determined. Based on the air conditioning loads' aggregated model, the dynamic characteristics of air conditioning load providing trusted reserve were analyzed. Through a large number of simulation experiments, nonlinear regression analysis was carried out on the experimental data affecting the reserve time and capacity characteristics, and the analytical expressions of dynamic response time, reserve capacity and external parameter distribution were fitted to provide time and capacity basis for predicting the reserve characteristics of aggregated air conditioning loads.
