Abstract

Safety analysis is an essential tool for ensuring the economic and stable operation of integrated energy systems and is a crucial component of the energy management system. Given that the security region of tightly coupled electric-gas-heat integrated energy systems has not been extensively studied, this paper establishes the security region model and the total energy supply capability model for the integrated energy system. It discusses and analyzes the total energy supply capability and security region characteristics of the tightly coupled electric-gas-heat integrated energy system, highlighting the impact of coupling nodes on the thermal system’s heating capacity and the relationship between the total energy supply capability and load size.
