Considering the equation and inequality constraints of four parts including power system, gas system, thermal system and element output, the paper aims at constructing a multi-scenario Electric-Gas-Thermal interconnection integrated energy system with energy storage elements and wind turbine, which pointing at the maximum energy supply capacity of Electric-Gas-Thermal integrated energy system. The Gurobi solver is invoked in MATLAB to solve the coupling IEEE39- node power system, the 6-node gas system and the 6-node thermal system. The energy supply capacity of normal situation, electric power system N-1 fault scenario, gas system N-1 fault scenario, thermal system N-1 fault scenario are calculated. Measuring the maximum energy supply capacity of the Electric-Gas-Thermal integrated energy system can provide decision support for the safe operation of the integrated energy system. It is more conducive to the reasonable planning of load distribution and the increase of system operation reliability.
