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。
In order to control the demand response and assist the power system operation by using the load of electric heat pump, the thermodynamic dynamics modeling mechanism of typical electric heat pump equipment is discussed in this paper. The thermodynamic dynamics are described by the equivalent thermal parameter (ETP) Then a load demand model constructed by multiple electric pump loads is constructed. On this basis, four kinds of electric pump load control strategies are designed and evaluated: 1 constant temperature setting strategy; 2 clipping strategy; 3 early heating strategy; 4 improved early heating strategy and their respective characteristics. The related control strategy can achieve peak load, improve grid load rate and improve power system economy.
