Abstract: The electricity, heat and gas coupling integrated energy system (IES) contains abundant slow-dynamic inertial resources. Given the similar characteristics of thermal and gas systems in which both systems can provide extra buffer space to accommodate energy fluctuations, this paper introduced a unified gas-thermal inertia model based on their unified theoretical frameworks, mathematical forms and supporting capability curves with sufficient consideration of convenient field utilization. In the power shortage support strategies proposed in this paper, unified gas-thermal inertia was then utilized as a new power support form on the original basis of conventional electricity utilization. The proposed strategy was assessed via an actual scenario, and the results verified the economy and environmental friendliness of the participation of unified gas-thermal inertia in power shortage support.
