摘　　要：差动调速型风电机组可在无需整流-逆变装置下与电网友好连接,为大规模风电并网和特大型风电装备的研制提供了新的技术途径。面向国家“双碳”需求,以提高风电消纳能力及并网运行稳定性、经济性为导向,提出了一种基于差动调速的风氢联合发电系统方案,并分析了其基本结构和调速原理,构建了关键单元的数学模型。为确保风氢联合发电的系统稳定、经济运行,在综合考虑风电出力及负荷需求等不确定性因素条件下,建立了制氢储能系统的容量优化模型;在保持高水平风能利用的条件下,完成了制氢储能系统的容量配置,并揭示了关键参数对容量配置的影响规律。搭建了所提风氢联合发电系统的仿真模型,在不同风速条件下,验证了所提方案的原理可行性及其在运行性能上的优越性。The wind power generation system equipped with a speed regulating differential mechanism(SRDM)is able to be connected in a friendly manner to power grid without the need of partially-or fully-rated converters.The novel alternative transmission schemes can provide a new effective technical approach for not only the large-scale wind power grid-connected consumption but also the development of high-power wind generation equipment.In response to the national imperative for the carbon neutral and peak sustainability,with a primary focus on enhancing wind power integration,grid operation stability and economy,this paper presents a fundamental framework for a novel power generation system,in which a hydrogen energy storage unit is integrated into the SRDM-based wind turbine.The study encompasses an in-depth analysis of the proposed scheme's overall architecture and speed regulation principles,alongside the development of mathematical models for critical system components.Moreover,to ensure the stable and economical operation of the proposed wind-hydrogen system,a capacity optimization model for the hydrogen storage unit is formulated,taking into account uncertainties such as wind power output and load demand.While maintaining a high level of wind energy utilization,the configuration of the hydrogen storage system is completed,shedding light on the influential patterns of key parameters on the capacity configuration results.Finally,a simulation model is constructed for the proposed scheme,through which the feasibility of the proposed concept and its superior operation performances are all verified under various wind speed conditions.
