摘要

本文研究了北欧电力系统中需求频率储备(DFR)的有效性。由于热泵具有切换灵活、对用户干扰小、应用前景广阔等优点,本文选择热泵作为DFR的代表。建立了热泵机组热力学模型,研究了DFR的动态特性。两个DFR控制逻辑,根据不同的设备特点设计,实现到热泵模型。在本研究中,DFR同时作为扰动和正常运行储备,以满足丹麦输电系统运营商(TSO)对频率储备的要求。据此,设计了应急和正常运行两种场景。仿真模型在RTDS中实现,并利用该仿真模型对所开发的频率响应器件(SmartBox)进行了硬件在环(HIL)测试。

Study of demand as frequency controlled reserve in Nordic power system
This paper investigates the efficacy of Demand Frequency Reserve (DFR) in Nordic power system. Heat pump, due to its switching flexibility, less disturbing impacts to customers and promising future in application, is used to represent DFR in the study. Thermodynamics of the heat pump unit is modelled to investigate the dynamic behaviour of DFR. Two DFR control logics, designed according to different appliance features, are implemented into the heat pump model. In this study, DFR acts as both disturbance and normal operation reserves to fulfill the requirement of frequency reserve by Danish Transmission System Operator (TSO). Accordingly, two case scenarios are designed for the contingency and normal operation, respectively. The simulation models are implemented in RTDS, by means of which the Hardware In the Loop (HIL) test of the developed frequency response device (SmartBox) is carried out.
