The rising demand for high-density power storage systems such as hydrogen, combined with renewable power production systems, has led to the design of optimal power production and storage systems. In this study, a wind and photovoltaic (PV) hybrid electrolyzer system, which maximizes the hydrogen production for a diurnal operation of the system, is designed and simulated. The operation of the system is optimized using imperialist competitive algorithm (ICA). The objective of this optimization is to combine the PV array and wind turbine (WT) in a way that, for minimized average excess power generation, maximum hydrogen would be produced. Actual meteorological data of Miami is used for simulations. A framework of the advanced alkaline electrolyzer with the detailed electrochemical model is used. This optimal system comprises a PV module with a power of 7.9 kW and a WT module with a power of 11 kW. The rate of hydrogen production is 0.0192 mol/s; an average Faraday efficiency of 86.9 percent. The electrolyzer works with 53.7 percent of its nominal power. The availability of the wind for longer periods of time reflects the greater contribution of WT in comparison with PV towards the overall throughput of the system.

“…Reactive power and voltage compensation using series-shunt (hybrid) topologies has been one of the effective techniques in improving the LVRT capability of the large scale of the wind farm level at the point of common coupling. The unified power quality conditioner (UPQC) demonstrates there may be a possible solution to the technical grid integration problems coming from the wind-driven FSIG [128][129][130]. Fundamentally, UPQC which is an integration of series and shunt VSC have been commonly studied by many researchers as the ultimate device to improve voltage sag, voltage unbalance, harmonics, dynamic active and reactive power regulation [131].…”

“…However, the capital cost involved in the installation of this device is higher than any other solutions devices because of its use of two converters. Therefore, authors in [129] propose a novel combination of resistive SFCL and UPQC illustrated in Fig. 20, in order to improve power quality problems and fulfill grid code requirements.…”

This paper presents a comprehensive review of various techniques employed to enhance the low voltage ride through (LVRT) capability of the fixed-speed induction generators (FSIGs)-based wind turbines (WTs), which has a non-negligible 20% contribution of the existing wind energy in the world. As the FSIG-based WT system is directly connected to the grid with no power electronic interfaces, terminal voltage or reactive power output may not be precisely controlled. Thus, various LVRT strategies based on installation of the additional supporting technologies have been proposed in the literature. Although the various individual technologies are well documented, a comparative study of existing approaches has not been reported so far. This paper attempts to fill this void by providing a comprehensive analysis of these LVRT methods for FSIG-based WTs in terms of dynamic performance, controller complexity, and economic feasibility. A novel feature of this paper is to categorize LVRT capability enhancement approaches into three main groups depending on the connection configuration: series, shunt, and series-shunt (hybrid) connections and then discuss their advantages and limitations in detail. For verification purposes, several simulations are presented in MATLAB software to demonstrate and compare the reviewed LVRT schemes. Based on the simulated results, series connection dynamic voltage restorer (DVR) and shunt connection static synchronous compensators (STATCOM) are the highly efficient LVRT capability enhancement approaches.

“…With the recent breakthrough of economical second-generation high-temperature (HTS) wires, the SFCL has become more viable [11]. There have been few efforts that are deployed the RSFCL by incorporating a double fed induction generator (DFIG) [12], [13] and fixed speed induction generator (FSIG) [14], [15] to demonstrate sufficient operation of the grid under fault conditions. This paper proposes the implementing an RSFCL as additional self-healing support along with a back-to-back converter for PMSG in order to ameliorate dc-link voltage smoothness and the LVRT capability by controlling the fault current and thereby enlarging the active power capacity of existing farm.…”

This paper describes the effective study in optimal design of a combinatorial resistive superconducting fault current limiter (RSFCL) and a wind turbine (WT) system. In the proposed scheme, the permanent magnet synchronous generator (PMSG) based on coordinated control strategy is also considered to provide a reactive power support as well as retaining the active power production during and after the fault condition according to the certain grid code requirements. The comprehensive electro-thermal model demonstrating the RSFCL damping performance is applied as additional self-healing support outside the WPP to attenuate exceed current in faulty conditions. The results show that the optimal selection of RSFCL can increase the active power generation capacity of the WT, thereby enhancing the dc-link voltage smoothness as well as the low voltage ride-through (LVRT) capability of the wind farm. However, any alteration in the dimensions of the superconducting wires as well as fault durations can influence both the voltage reduction and the reactive power supplied by the WT at the point of common coupling (PCC). Thus, the numerical analysis is implemented to show the pros and cons of variation of RSFCL parameters on the optimal performance of WT system. Index Terms--Lowvoltage ride-through (LVRT), Multicriteria decision making (MCDM), Superconducting fault current limiter (SFCL), Wind turbine (WT).
