Abstract:Different energy storage technologies have their own characteristics in terms of response properties, economic costs, capacity scale, and so on, and are suitable for different application scenarios. The hybrid energy storage system, which is formed by two or more energy storage devices, can often integrate the technical and economic characteristics of all parties and show more excellent performance. Aiming at the problems of the existing power grid being increasingly affected by the output fluctuations of renewable energy, the technical bottleneck in promoting the consumption, and the high pressure of peak shaving, a hybrid energy storage system composed of VRB(Vanadium Redox flow Battery) and AA-CAES(Advanced Adiabatic Compressed Air Energy Storage) is proposed, and a capacity optimization configuration model considering large-scale wind power integration is established. Firstly, the spectrum characteristics of wind power output are analyzed, and a wind power distribution strategy based on empirical mode decomposition is proposed. Then, based on this strategy, a bi-level capacity optimization configuration model of hybrid energy storage system is constructed. The upper layer decides the configuration capacity of hybrid energy storage system with the goal of minimizing the total economic input in the planning period, while the lower layer decides its day-ahead generation plan with the goal of minimizing the system operation cost. Finally, the proposed model is simulated and verified based on the typical daily wind power and load data of an actual power grid. The results show that the proposed capacity optimization configuration model of hybrid energy storage system can not only meet the multiple performance requirements of power grid, but also effectively improve the economy of the system.
Keywords:large-scale wind power integration   hybrid energy storage system   capacity configuration   vanadium redox flow battery   advanced adiabatic compressed air energy storage
