| 摘要: |
| 针对氢能利用单一、可再生发电不确定性高和系统灵活调节能力差等问题，提出了一种考虑电氢耦合和双层不确定性的园区综合能源系统优化运行方法。构建集成电氢模块和掺氢热电联供模块的多能耦合综合能源系统模型；建立以综合能源运营商为上层领导者，产消用户为下层跟随者的互动博弈框架；充分考虑博弈关系下双层可再生能源出力不确定性的影响，采用基于Wasserstein距离的分布鲁棒机会约束建立双层分布鲁棒优化模型。利用卡罗需-库恩-塔克条件、强对偶定理和大M法将提出的具有平衡约束的数学问题转化为线性规划问题，通过Gurobi求解器进行求解。仿真结果表明所提模型和方法有效提高了系统的经济性和灵活调节能力。 |

| Abstract: |
| To address the problems such as single hydrogen energy utilization, high uncertainty of renewable power generation, and poor flexible regulation capability of the system, an optimal operation method of park integrated energy system considering electro-hydrogen coupling and dual-layer uncertainty is proposed. A multi-energy coupling integrated energy system model integrating electro-hydrogen module and hydrogen-doped combined heat and power(HDCHP) module is constructed. An interactive game framework is established with the energy system operator(ESO) as the upper-layer leader and prosumers as the lower-layer followers. The impact of two-layer renewable energy output uncertainty under the game relationship is fully considered, a dual-layer distributed robust optimization model is established by using the distributionally robust chance constraint(DRCC) based on the Wasserstein distance. The proposed mathematical problem with equilibrium constraints is transformed into a linear programming problem by utilizing Karush-Kuhn-Tucker(KKT) conditions, strong duality theorem, and Big M method, which is solved by Gurobi. Simulative results show that the proposed model and method effectively improve the economic efficiency and flexible regulation capability of the system. |
