Abstract: Wind Engineering, Ahead of Print.
The doubly fed induction generator (DFIG) is the most popular induction generator for onshore wind energy conversion system (WECS). Therefore, the purpose of research is to optimize power transfer from DFIG to power grid which requires frequency and voltage stability in power converters. Hence, the single-stage and multistage power converter topologies associated with grid-integrated DFIG are thoroughly examined in this work. In the single stage, a matrix converter and cycloconverter are used. Whereas, the multistage topologies include two-level back-to-back (2L-B2B) converter, Z-source converter, and multilevel converters. Furthermore, three-level neutral point clamped (3L-NPC) voltage source converters with battery energy storage systems (BESS) and modified superconducting fractional order terminal sliding mode controllers (MSTFOTSMC) have been used with multilevel converter both at rotor side converter (RSC) and grid side converter (GSC) for stabilized generated voltage and higher power output. The MATLAB simulation results demonstrate that the system effectively controls fluctuations in voltage and current thereby improving the power quality in unbalanced situations.

Abstract: Wind Engineering, Ahead of Print.
This paper introduces a novel disturbance observer-based finite-time adaptive neural control approach to optimize wind power conversion in a doubly fed induction generator-based wind turbines (DFIG-WT). This control strategy offers appealing features including rapid finite-time convergence, both transient and steady-state performance enhancements, and robustness against external disturbances and inherent model uncertainties. The control strategy integrates the neural networks estimation capability with the interesting proprieties of the finite-time control method to achieve efficient wind power conversion. Closed-loop finite-time stability is conducted using the finite-time Lyapunov stability concept of nonlinear systems. The developed control strategy’s effectiveness is confirmed through numerical simulation.

Abstract: Wind Engineering, Ahead of Print.
This paper investigates the effects of slots on wind turbine blade sections on the reduction of fluid loads on the airfoil in turbulent flows. The governing conversation equations were discretized using the finite volume method (FVM), numerically simulating an unsteady flow with a turbulent regime. It was found that slots at ΨA70° and high angles of attack (AOAs) improved the aerodynamic performance of the airfoil and delayed the stall by 2°. The Cl-Cd ratio was 31.49%, 79.22%, and 29.66% higher in the slotted airfoil than in the non-slotted one at an AOA of 18°, 20°, and 22°, respectively. Furthermore, slots with ΨA70° at AOAs of 20° and 22° substantially reduced lift and drag variations on the airfoil.

Abstract: Wind Engineering, Ahead of Print.
The accurate prediction of ultra-short-term wind speed has important theoretical significance and practical application value. In this paper, a combination prediction model of ultra-short-term wind speed based on variational mode decomposition is proposed. Firstly, the variational mode decomposition algorithm is introduced to decompose the ultra-short-term wind speed and obtain the components of different frequency. The approximate entropy algorithm is used to calculate the complexity of each component. According to the calculation results, echo state network is selected to predict high complexity components, support vector machine is used to predict medium complexity components, and autoregressive integrated moving average model is used to predict low complexity components. Then, the predicted values of each component are added to get the final prediction result. Gray wolf algorithm is used to optimize the model parameters of support vector machine and echo state network. In addition, the approximate entropy calculation results show that compared with the original ultra-short-term wind speed, the complexity of the components obtained by the variational mode decomposition algorithm is reduced, which makes the modeling of the ultra-short-term wind speed system simpler. Finally, the validity of the model is verified by taking the ultra-short-term wind speed data of 5 minutes and 10 minutes sampling period actually collected as the research object. The results show that the prediction model proposed in this paper has better performance than other single or combination prediction models.

Abstract: Wind Engineering, Ahead of Print.
Global energy is in a major shift from energy using fossil sources to renewable energy using more sustainable energy sources. The wind is the clean and inexhaustible one of renewable energy resources that is available in most parts of the world. In order for wind power generation to meet more ambitious targets around the world, it is necessary to understand all the physics behind process of wind generation. The most interesting of this process is the power coefficient which involves the real characteristics of the wind turbine as a function of the generated power. Up to now, the power coefficient does not yet have a general form but are fitted as mathematical functions from manufacturer data measured from popular wind turbines in the world. In this paper, we develop an analytical physics-based method to estimate the power coefficient general for various wind generation systems of horizontal-axis wind turbines (HAWT). Instead of 12 parameters in semi-experimental exponential formula , our power coefficient uses only 5 parameters with their physical meanings. By varying these five parameters we also obtain the power coefficients fitted from experimental data.

Abstract: Wind Engineering, Ahead of Print.
Savonius rotor is a vertical axis wind rotor that has a good attention due to its lower fabrication cost and receives air from any direction. In the present computational work, various arrangements will be introduced for the blades of Savonius rotor with the aim of improving the performance. Two-dimensional simulations are performed using ANSYS with the presence of the SST k-ω as a suitable turbulence model to analyze the flow around the rotor. The computational results include 12 different arrangements namely rotor 1 to rotor 12. The difference between all the studied rotors is the arrangement of an additional shape to the original blade of Savonius rotor. The addition of a flipper with a radius of curvature equivalent to 1.73 of the radius of the blade generates the best performance with an improvement of 38.5% in the power coefficient compared to the traditional rotor. The best design (known as case 1) has a pair of blades with a distance of 15% of the blade radius, which improves the performance by 28.3% compared to the traditional rotor.

Abstract: Wind Engineering, Ahead of Print.
The paper proposes a theoretical line loss calculation method for low-voltage terrace areas with a high proportion of wind power access. The method is based on two-stage hybrid clustering. The operating parameters of the station area are processed, and SOM-K-means hybrid clustering is used to determine the typical scenarios and time segments of typical monthly wind power curves. A theoretical model for calculating line loss power in distribution networks based on hybrid clustering is proposed. Additionally, a theoretical model for calculating line loss rate is suggested for different modes with a high proportion of wind power participation. Finally, this paper verifies the validity of its method and model by applying them to an actual station area with wind power output and load curve, completing the theoretical calculation, and comparing the results with those of the tidal method. This provides a fast and accurate calculation method for theoretical line loss calculation.

Abstract: Wind Engineering, Ahead of Print.
This research introduces a resilient Sensor-Less 1st Sliding Mode (SL-FOSM) approach employing a novel observer, the Artificial Neural Network with Model Reference Adaptive System-Adaptive (Neural-MRAS), for wind turbine chains. The proposed model is implemented on a Doubly Powered Induction Generator (DPIG) operating under genuine variable speed conditions in the Adrar region in Algeria. The control objective is to independently regulate the active and reactive power of the DPIG stator, achieved through decoupling using the field-oriented control technique and control application via FOSM-C. Notably, this methodology reduces both the control scheme cost and the DPIG size by eliminating the need for a speed sensor (encoder). To enhance the MRAS-PI, an Artificial Neural Network (ANN) is suggested to replace the typical classical Proportional-Integral (PI) controller in the adaptation mechanism of MRAS. The rotor position estimation is scrutinized and discussed across various load conditions in low, zero, and high-speed regions. Optimal controller parameters are determined through particle swarm optimization (PSO). The results demonstrate that the proposed observer (Neural-MRAS) exhibits compelling attributes, including guaranteed finite time convergence, robust performance in response to speed variations, high resilience against machine parameter fluctuations, and adaptability to load variations when compared to the MRAS-PI. Consequently, the estimated rotor speed converges to its actual value, showcasing the capability to accurately estimate position across different speed regions (low/zero/high).

Abstract: Wind Engineering, Ahead of Print.
The current widespread support of decarbonization and green energy has led to a notable increase in the incorporation of clean energy sources (CESs) in microgrids (MGs). CESs are intermittent, and if they become more widely used in MG, managing uncertainty will become more difficult. This is true even with the environmental and financial advantages of CESs. In this paper, the operation of a DC/AC MG, which integrates solar photovoltaics (PVs), wind farms, fuel cells (FCs), and battery chargers (BCs), is investigated and analyzed under uncertain conditions. The MG’s main energy source is thought to be the PV, while the FC and BC assist in maintaining the MG’s stability. A variable AC load and an electric vehicle charging system are fed by the MG. Two control system approaches have been designed and evaluated. The first is a new design of fuzzy logic controller (FLC), which is provided and applied to provide an adequate energy management system (EMS) for the investigated MG considering uncertainties of CESs. Moreover, JAYA-based optimal control has been developed. The proposed EMS is utilized to adapt the fuel consumption for the FC and the charging concept of Li-ions and to provide a constant load bus voltage. In order to demonstrate the effectiveness of the suggested technique, the proposed novel design of FLC and JAYA-based controllers’ performance is tested under partial shadowing of the PV with abrupt load fluctuations of 25% and contrasted with the PI controller methodology, where it is designed using the Ziglar Nicolas technique. The obtained findings show how the suggested control technique improves the system and the MG’s dynamic performance. A MATLAB\Simulink simulation is carried out, and the outcomes demonstrate the effectiveness and superiority of the suggested strategy in managing uncertainty.

Abstract: Wind Engineering, Ahead of Print.
This study explores modifications to the blade airfoil cross-sections aimed at improving the efficiency of a 10 kW Bergey EXCEL horizontal axis small wind turbine. Specifically, the research focuses on altering the camber and thickness of the turbine’s baseline airfoil, designated as SG6043. Using advanced aerodynamic analysis tools like QBlade, the performance of the modified airfoils EY05-10 and EY08-9 is evaluated. The findings show that these modified airfoils achieve a higher lift-to-drag ratio compared to the baseline. These improved airfoils are then incorporated into the turbine’s blade geometry using the WT_Perf software. The enhanced turbine’s power generation capabilities are subsequently assessed with FAST (Fatigue, Aerodynamics, Structures, and Turbulence) version 8. Results reveal that at a wind speed of 15 m/s, the turbine with the modified blades produces 6.7% more power and 20.47% more annual energy than the original turbine.

Abstract: Wind Engineering, Ahead of Print.
A Vertical Axis Wind Turbine (VAWT) comprises multiple parts constructed from different materials. This complexity presents challenges in designing the blade structure. In this study, we investigated a structural optimization of a small-scale blade for a VAWT, with Finite Element Analysis (FEA) model. The purpose is to minimize the blade mass while adhering to a suite of critical wind conditions according to the IEC 61400-2 Standard. The structure made from Aluminum material simulates structure’s global behavior to determine maximum stress and deflection levels. The same structure is modeled using Glass/Epoxy composite for optimizing its design. Twenty combinations of Glass/Epoxy layers, varying in ply thickness and orientation, are simulated to find the most suitable combination. Results demonstrated that the optimization case [45°/90°/0°/−45°] obtained the minimum values of stress and deflection, is 59% lighter than Aluminum blade (initial design). The designed Glass/Epoxy composite blade is acceptable and recommended for structural safety.

Abstract: Wind Engineering, Ahead of Print.
Wind power only received occasional attention since the introduction of electricity until the 1970s, when a revived interest in alternative energy sources spurred the development thread that led to today’s wind turbines. Although attention and financial support at the time were directed toward government-funded MW-scale wind turbines, the small models developed in the late 1970s for the Danish market were ultimately the way forward. The wind industry has since matured, as evidenced by the lower specific power and higher capacity factors of recent turbine models and the similarity between their power curve shapes. Moreover, this study highlights two historical accomplishments by Europeans that are sometimes incorrectly credited to Americans: the first wind turbine to generate electricity was built in 1883 by Austrian Josef Friedländer and the Danish Agricco (1919) became the first public grid-connected wind turbine.

Abstract: Wind Engineering, Ahead of Print.
This study examines how adjusting aspect ratio (AR) and adding triangular dimples to the airfoil can enhance H-type Darrieus wind rotor (H-rotor) performance under low wind speeds (4, 6, and 8 m/s) using wind tunnel testing. Results show optimal performance at an AR of 1.0 for both standard and Triangular dimple airfoil H-rotors, with variations at different wind speeds for other aspect ratios. Triangular dimple-equipped H-rotors demonstrate improved self-starting capability and a wider operational range of tip speed ratio (TSR) compared to standard rotors, ensuring reliability across diverse wind conditions. Moreover, the triangular dimple rotor achieves a nearly 13.6% increase in maximum coefficient of power ([math]) compared to the dimple-free H-rotor at 4 m/s wind speed. This study underscores the efficacy of adjusting AR and integrating triangular dimple blades to enhance H-rotor performance, particularly in low wind speeds.

Abstract: Wind Engineering, Ahead of Print.
While the direct power control (DPC) approach has proven effective in improving the efficiency of wind energy conversion systems (WECS) using doubly fed induction generators (DFIG), its applicability is currently confined to a single usage and has not been extended to meet numerous applications. This work aimed to modify the implementation of DPC in WECS-DFIG for several objectives. This is accomplished by updating the reference power of the conventional DPC method into an adapted one to achieve two goals independently. The first objective is to track the maximum power during wind speed variations. This tracking is performed by updating the reference power to match the maximum available power at the current wind speed. The second purpose is to ensure that the WECS remains connected to the grid and continues to operate smoothly even in the event of faults; supporting fault-ride through (FRT) capability. That is achieved by reducing the reference power during these faults. The discrimination between these two objectives is based on the voltage level at the point of connecting WECS to the grid. The controller provided is an improved fractional order PI controller developed using arithmetic optimization technique (AOA). A comparison between the AOA and cuckoo search is presented. The results demonstrate the efficacy of the suggested configuration and regulator in enhancing the performance of integrating DFIG into the WECS in the presence of wind fluctuations and short circuit faults occurring. It is worth noting that AOA is better than cuckoo search in fine-tuning the settings of the FOPI controller.

Abstract: Wind Engineering, Ahead of Print.
Wind resource assessment of 12 sites in low-wind regions of Pakistan was conducted, focusing on wind data characteristics and wind speed distributions. A comparative performance evaluation of Power Law (PL) and Logarithmic Law (LogL) for interpolation (at 60 m) and extrapolation (at 80 m) of wind speed was performed. Performance analysis of over 500 commercial wind turbines was carried out in terms of Net Capacity Factor (NCF). The wind power density of all sites at 50 m, ranges from 33 to 244 W/m2, categorizing wind power class as either poor or marginal. The performance evaluation shows that PL and LogL perform better for interpolation and extrapolation respectively, at the same height. A turbine with cut-in and rated speed of 1.0 and 10 m/s respectively, achieves maximum NCF across all sites due to lowest cut-in speed. The NCF of the turbine for marginal wind power class sites ranged from 53% to 58%.

Abstract: Wind Engineering, Ahead of Print.
Accurate short-term wind power prediction is of great significance for the scheduling and management of wind farms. This paper proposes a model for short-term wind power prediction. Firstly, on the basis of traditional long short-term memory network, the peephole connections is added. The improved long short-term memory network is more stable compared to traditional long short-term memory neural networks and is suitable for regression prediction. Secondly, chaotic mapping, adaptive weights, Cauchy mutation, and opposition-based learning strategies are introduced to improve the sparrow search algorithm, and applied to optimize the four hyper-parameters of the long short-term memory network, greatly improving the prediction accuracy of the network. The effectiveness of the model is validated using two short-term wind power datasets with sampling times of 10 and 30 minutes respectively, combined with some fitting curves and performance indicators. The comparison results indicate that the proposed short-term wind power prediction model has high prediction accuracy.
