智能电网的发展为温控负荷参与电网调度提供硬件支撑。为研究温控负荷为电网提供负荷调度的容量特性,首先根据居民典型温控负荷的工作特性,建立可准确描述单个温控负荷工作原理的物理模型,并在此基础上通过核平滑技术建立了小区温控负荷的聚合模型,进而求得聚合负荷功率需求与相关参数的变化特性。最后对小区温控负荷的可调度容量做了相关特性分析,算例结果验证了所述方法的有效性。
The development of smart grid provides hardware support for the participation of thermostatically-controlled loads on power grid dispatching. To study the capacity characteristic of energy support provided by the residential thermostatically-controlled load, this paper builds the physical model of individual thermostatically-controlled load based on its working characteristic. On the basis of this model, aggregation models of community thernmstatically-con- trolled loads are established by Kernel smoothing technique, and then, the variation characteristics of aggregated load power requirements and related parameters can be obtained. Finally, the relevant analysis of the schedulable commu- nity thermostatically-controlled loads is made, and the effectiveness of the proposed method is verified by the simula- tion results.
