Abstract: 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.
