Dispatching Potential Evaluation of Thermostatically Controlled Loads Based on Realistic Customer Electricity Data in China

With the development of the information and communication technologies, demand response (DR) can be realized more easily and considered as one of effective methods to provide regulation services for the power system. Among the flexible loads for DR, thermostatically controlled loads (TCLs) are regarded as one of the most important loads, because of the large share of power consumption and suitable regulation characteristics without impacting customers' comfort. However, the dispatching potential of TCLs is difficult to be evaluated due to the limitation of measuring equipment. Faced with this issue, this paper proposes a method for evaluating the dispatching potential of TCLs based on the realistic customer electricity data in China. The relationship between the dispatching potential of TCLs and the ambient temperature is obtained. In this way, the system operator can calculate the dispatching potential of TCLs according to the weather forecast. The effectiveness of the proposed model and method is verified in the case studies.
