摘要：
The gas-fired unit in the gas-electric coupling system is used as the load of the gas network, and its working state will be subject to the operation state and gas supply strategy of the natural gas system. So, the assessment of power grid risk must take into account the influence of the reliability of the gas network. In this paper, the gas-electric coupling system is modeled, the sequential Monte Carlo method is applied to simulate the natural gas network fault, and the gas supply flow is calculated for the pipeline network in different scenarios. The uncertainty of natural gas supply caused by the fault is transmitted to the grid side, and the risk evaluation index of the power system is established. Combined with specific examples, the risk assessment of node voltage and line load is carried out.
