摘要：
The integrated energy system with coupling of electricity-gas-thermal multi-energy has the characteristics of multiple time scales, and the flexibility from slow dynamics of gas and thermal system could be utilized. When the external conditions change, state changes of both gas and thermal systems relatively lag behind, which could provide power support for integrated energy systems within a certain time period. According to this characteristic, gas and thermal inertia in integrated energy systems is defined and its power supply model is formulated based on the physical rationale of gas and thermal systems. Then, a reserve allocation scheme considering gas and thermal inertia is proposed on the basis of the proposed power support ability of gas and thermal inertia. Case results demonstrate that the support ability of gas and thermal inertia increases the diversification of reserve allocation means of the integrated energy system and improves the flexibility and economy of coordinated operation of the integrated energy system. © 2021 Automation of Electric Power Systems Press.
