摘要
为利用电热泵负荷进行需求响应控制,辅助电力系统运行,本文讨论了典型电热泵设备的热力学动态的建模机理,用二阶等值热力学参数ETP(equivalent thermal parameter)模型描述了其热力学动态,进而构建了多个电热泵负荷聚合而成的负荷需求模型。在此基础上,设计并评估了4种电热泵负荷控制策略:1恒定温度设定值策略;2削峰策略;3提前加热策略;4改进的提前加热策略,并分析了各自的特点。相关控制策略可实现削峰填谷,提高电网负荷率,改善电力系统经济性。
Abstract： In order to utilize electric air-conditioners to assist the operation of power systems through demand response programs, modeling method is discussed in this paper to simulate thermal dynamics of typical residential electric air- conditioners. Specifically, an equivalent thermal parameter model with two-order differential equations is applied. Fur- thermore, aggregated load demand model is established for residential electric air-conditioner groups. Based on the de- mand model, four control strategies for residential electric air-conditioners are designed and evaluated, including： ① constant thermostat setpoint; ②curtailment; ③pre-heating; ④improved pre-heating. The proposed strategies are capa- ble of decreasing the peak-average rate of the power grid, and thus the economy of the power system would be improved.
