A sensitivity analysis method for the wind power capacity of integrated energy systems based on unified optimal power flow is proposed, aiming at the large‐scale grid‐connected wind power problem of integrated energy systems with multiple energy sources and strong coupling characteristics. Based on the unified optimal power flow model of integrated energy system with power system, heat system and gas system, this study establishes the sensitivity analysis method of integrated energy system operation state. Based on the sensitivity matrix, the influence of wind power consumption capability by capacity of energy coupling unit on wind power consumption is analysed. The results of the example show that the proposed method can provide auxiliary information for the safe and stable operation of the integrated energy system, and effectively improve the wind power acceptance level.
