“…In addition, the cut‐in and cut‐out limits are stretched out by the IWT that causes creating power even at low speeds, for example, 1–2 m s −1 . [ 7,9 ] The IWT yield power is characterized by Equation (2). [ 9 ]

“…[ 8 ] As a result, the IWT's capacity to generate power with two generators operation is 1.5 times higher than single IWT, and three generators operation is 1.7 times higher than two generators operation. [ 9 ] Apart from high‐power generation with multiple structures of IWT, due to reducing the uncertainty of generator problems, using multigenerators at the same time, the reliability of the electrical network will be increased. Moreover, this structure is usable for various speeds, places, and applications because of the low threshold speed and scalability.…”

Herein, optimal configuration and microgrid's energy control based on day-ahead planning is proposed. For this purpose, fossil fuel resources are equipped with carbon capture utilization and storage (CCUS) technologies, and INVELOX turbines are proposed in microgrid's planning. The microgrid's overall contamination and cost are considered as objective functions. To encourage the consumers to utilize renewable resources, obtained profit from CCUS is assigned as incentive programs for buying their extra energy. Also, the problem is modeled as a mixed-integer linear programming (MILP), and the epsilon constraint and fuzzy satisfying approach are utilized to tackle and accomplish the best and optimal solution. The outcomes show that overall costs and contamination are

“…Allaei and Andreopoulos (2014) have been the first to present on-field measurements thus demonstrating that INVELOX can enhance the daily energy production ratio. In their following works (Allaei, 2012;Allaei and Andreopoulos, 2014;Allaei et al, 2015), they have also studied the flux within and outside of the prototype by performing numerical simulations, also varying the number of turbines within the Venturi section. Nevertheless, in literature, there are few evidences of analysis of the INVELOX geometry (Anbarsooz et al, 2017).…”

This article focuses on evaluating the performance of a relatively new system of a ducted wind turbine with an omnidirectional capture system, the INVELOX system. In the present study, the improvement of such patented system has been developed by performing a detailed numerical analysis varying several geometrical parameters and analysing the effect of changing wind velocity and wind direction. At first, the model validation was performed and the performance of the original system against the wind direction changes was analysed observing that the highest speed ratios are obtained for two specific directions. Based on the previous results, the most critical features of the system have been identified, and then it has been approached a geometric improvement of the system aiming at increasing the system productivity. The results show there is a possibility to largely improve the overall design and extract more energy from the wind respect with the original design.

“…With this modification, the VAWT could be not only operated in omnidirectional winds but also exhibited augmented wind energy. In addition to these approaches, various other methods have been developed to augment the performance of the VAWT, such as increasing the height of the installed location of the wind turbine, [18][19][20] utilizing the wind augmented by the space between buildings, 21 installing a wind collector on the roof of buildings 22,23 .…”

In order to augment the performance of vertical axis wind turbines, wind power towers have been used because they increase the frontal area. Typically, the wind power tower is installed as a circular column around a vertical axis wind turbine because the vertical axis wind turbine should be operated in an omnidirectional wind. As a result, the performance of the vertical axis wind turbine depends on the design parameters of the wind power tower. An experimental study was conducted in a wind tunnel to investigate the optimal design parameters of the wind power tower. Three different sizes of guide walls were applied to test with various wind power tower design parameters. The tested vertical axis wind turbine consisted of three blades of the NACA0018 profile and its solidity was 0.5. In order to simulate the operation in omnidirectional winds, the wind power tower was fabricated to be rotated. The performance of the vertical axis wind turbine was severely varied depending on the azimuthal location of the wind power tower. Comparison of the performance of the vertical axis wind turbine was performed based on the power coefficient obtained by averaging for the one periodic azimuth angle. The optimal design parameters were estimated using the results obtained under equal experimental conditions. When the non-dimensional inner gap was 0.3, the performance of the vertical axis wind turbine was better than any other gaps.
