基于两阶段鲁棒区间优化的风储联合运行调度模型

In order to comprehensively and accurately take into account the uncertainty and accommodation ability of wind power and consider both the economy and reliability of system operation, the discrete decisive variables of conventional generator and ESS(Energy Storage System) are introduced into the robust interval economic dispatching model with an optimizable wind power uncertain interval, and a double-level robust interval unit commitment model is established for joint operation of wind-storage system. The invalid dual transform caused by coupling relation between the discrete and continuous variables in the calculation process makes the model hard to be solved, for which a two-stage iterative solution method based on Benders decomposition is proposed. Simulation analysis shows that the proposed model can consider the impact of uncertainty and accommodation ability of wind power on economy and reliability of system operation more comprehensively when determining the joint operation mode of wind-storage system.
