Frequency Response Strategies Considering Gas-thermal Inertia in the Integrated Energy System Cairan Miao, Qi Wang*

Abstract

Due to the intermittence of renewable energy and its large-scale access in the power grid, frequency stability control faces severe challenges. To address this issue, this paper considers gas-thermal inertia in the integrated energy system (IES) to provide frequency response. Due to their similar slow dynamic characteristics, this paper gives detailed explanations on power support characteristics of gas-thermal inertia, based on which presents a new method to provide frequency response in IES. The proposed method is tested in an actual scenario and the advantages of considering gas-thermal inertia are verified.
