Abstract

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.

为电力系统提供可靠备用的聚集空调负荷特性分析及计算方法

空调负荷汇聚后具有为电力系统提供备用的潜力。为实现集群空调负荷参与系统调度，提供可信备用容量，提出了一种集群空调负荷可信备用特性的分析计算方法。首先，确定待机动态过程的响应时间和可用备用容量;在空调负荷聚合模型的基础上，分析了提供可信储备的空调负荷的动态特性。通过大量的模拟实验，对影响备用时间和容量特性的实验数据进行非线性回归分析，拟合出动态响应时间、备用容量和外部参数分布的解析表达式，为预测空调综合负荷的备用特性提供时间和容量依据。
