摘　　要：不确定场景下鲁棒可行域能为虚拟电厂参与输电级调度提供定量出力估计。现有虚拟电厂鲁棒可行域研究未涉及电氢耦合系统,提出一种考虑电氢耦合的虚拟电厂鲁棒可行域模型与求解方法。首先,解析可逆固体氧化物电池双向电氢转换原理,构建电氢耦合虚拟电厂模型;其次,基于顶点投影凸包搜索法(projection convex hull search method,PC-SM),建立电氢耦合虚拟电厂鲁棒可行域模型;最后,针对电氢耦合虚拟电厂鲁棒可行域模型求解,利用列和约束生成算法(column-and-constraint generation,C&CG)求解PC-SM所提供凸包搜索方向下的顶点投影集,提出一种新的C&CG-PCSM耦合算法。算例仿真表明,所提模型与求解方法能够为电氢耦合虚拟电厂参与输电级调度提供定量出力估计理论支持。In uncertain scenarios,the robust feasible region can provide quantitative output estimation for virtual power plants to participate in transmission level scheduling.Existing research on the robust feasible region of virtual power plants has not addressed the electric hydrogen coupling system.A robust feasible region model and solution method for virtual power plants considering electric hydrogen coupling are proposed.Firstly,analyze the principle of bidirectional electro hydrogen conversion in reversible solid oxide cells and construct a virtual power plant model with electro hydrogen coupling;Secondly,based on the Projection Convex Hull Search Method(PC-SM),a robust feasible region model for a virtual power plant with electric hydrogen coupling is established;Finally,a new C&CG PCSM coupling algorithm is proposed for solving the robust feasible region model of a virtual power plant with electric hydrogen coupling,using the Column and Constraint Generation(C&CG)algorithm to solve the vertex projection set under the convex hull search direction provided by PC-SM.The simulation results show that the proposed model and solution method can provide theoretical support for the quantitative output estimation of virtual power plants with electric hydrogen coupling participating in transmission level scheduling.
