摘要(Abstract):
多乡村综合能源系统协同运行可提升能源利用效率与用能灵活性,因此提出一种计及电能交互的多乡村综合能源系统分布鲁棒优化运行策略。首先,考虑可再生能源出力和负荷需求的不确定性,引入基于Wasserstein距离的分布鲁棒优化模型,并利用Lipschitz函数理论将其转化为可求解的确定性等价模型。其次,搭建基于纳什谈判理论的多乡村综合能源系统电能共享合作调度模型,最小化系统协同运行总成本。针对各参与主体电能交互量的差异,提出一种基于非对称纳什议价机制的收益分配方法,采用交替方向乘子法进行求解,实现各主体合作收益公平分配。通过仿真算例验证,该策略能够有效降低系统运行成本,并在乡村综合能源系统间实现公平高效的合作运行。
To improve energy utilization efficiency and operational flexibility in multiple rural integrated energy systems(IESs), a distributionally robust optimization strategy is proposed for coordinated operation considering electricity interaction among systems. First, to address uncertainties in renewable energy generation and load demand, a distributionally robust optimization(DRO) model based on the Wasserstein distance is introduced, which is further reformulated into a tractable deterministic equivalent model using Lipschitz function theory. Second, a cooperative operation model for electricity sharing among multiple rural IESs is developed based on Nash bargaining theory, aiming to minimize the total cost of coordinated system operation. To handle disparities in electricity interaction among participating entities, a profit allocation method based on an asymmetric Nash bargaining mechanism is proposed, and the alternating direction method of multipliers(ADMM) is adopted for solution, enabling fair distribution of cooperative benefits. Simulation results demonstrate that the proposed strategy effectively reduces system operating costs while achieving fair and efficient cooperative operation among rural integrated energy systems.
