Hybrid drive wind power generation system, equipped with the speed regulating differential mechanism (SRDM), is able to be friendly connected to power grid without the need of partly-or fullyrated converters. The novel transmission schemes can promote not only the output power quality but also the low voltage ride through (LVRT) capability of the existing wind turbines (WTs). For the purpose of further improving the grid-connected operating performances of SRDM-based WT, this paper aims to develop a hybrid power production unit, in which the hydrogen storage system (HSS), comprising an electrolyzer, a hydrogen fuel cell and a supercapacitor, is integrated into SRDM-based WT. The basic architecture and numerical modelling methods of key subsystems in SRDM-based WT as well as in HSS are analyzed. After determining the eight different operating modes, a power supervision approach is synthesized for the proposed SRDM-based WT with HSS, by which the power flow management between energy sources and storage elements can be realized. Case studies are carried out in the presence of different randomly varying wind speeds and grid voltage faults. The satisfactory operating performances of the proposed wind-hydrogen hybrid system in terms of maximizing wind energy utilization, suppressing output power fluctuation and improving system continuous operating stability are verified.

“…The structure, control, and performance of a CVSWT with power splitting transmission and a free running planetary gearbox were proposed in Liu et al As shown in Figure , the main components of the CVSWT with power splitting transmission consist of a turbine system, a main gearbox, a free running planetary gearbox, an electrical excited SG, a servo motor, and a back‐to‐back converter. The main gearbox is with a 1 or 2 stage structure so that the rated speed of the main shaft at the high speed side is about 400 to 600 rpm.…”

Summary As a promising and potential alternative to conventional fixed or variable speed wind turbines, continuously variable speed wind turbines (CVSWTs) with variable transmissions offer improved power efficiency and enhanced power control capabilities. The CVSWTs can be generally achieved by adapting mechatronic variable transmissions in the turbine drive train for continuously variable speed operations for wind turbines. Therefore, this paper serves to provide an up to date and exhaustive review of the CVSWTs with mechatronic variable transmissions such as mechanical variable transmission, electrical variable transmission, and power splitting transmission. In this paper, the analysis of CVSWTs with different mechatronic transmission topologies is performed regarding basic configurations, dynamic characteristics, control principles, and experimental or simulation results. Review results indicate the feasibility of applying CVSWTs with such mechatronic transmissions and highlight superiorities of the CVSWTs with power splitting transmission. The CVSWT with power splitting transmission will be particularly suitable for megawatt‐scale turbine systems and will hence increase the economic competitiveness of these turbines due to its large power capacity and high reliability. The directions or challenges for future investigations of CVSWTs with such mechatronic transmissions are also presented to foster in‐depth understanding of such CVSWTs and their control strategies.

“…In [16, 17], the authors carried out important researches in terms of operating modes and maximum power extraction control strategy for hybrid drive WTs. In [18], Liu et al demonstrated experimental studies with a 66 kW testbed to investigate the feasibility, transient performances and power split behaviour of continuously variable speed WT. In recent years, Yin et al [19] summarised the current status as well as the future prospects of CVT‐based WTs and pointed out that the mechanical, hydraulic and hydro‐mechanical CVTs all have good potential to be effectively‐employed in high‐power WTs.…”
