【 摘 要 】

Thermostatically Controlled Loads (TCLs) are an important type of dispatch able resources to participate in power balancing in short-time scale, which have huge response potential and fast response speed. But since the response of TCLs is uncertain, it is difficult for the control center to get them directly. To solve this problem, this paper proposed a novel method to evaluate the uncertainty of TCLs response potential based on the aggregated model, which divided the response potential into two parts: expectation value and distribution characteristics. According to probability distribution, the uncertainty of TCLs potential was analyzed. Simulation results show the effectiveness of the method.
