“…Almost all of these innovative ideas were designed based on the platform of the traditional wind turbines which integrate a generator, shaft, blades, and tower. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] One of the most inventive ideas on how to generate electricity from the air discharged from ventilation systems in buildings within urban areas was presented by Chong et al, 17,18 who proposed installing a vertical-axis wind turbine above the discharged air of cooling towers. Based on this research, some adverse effects were observed on the performance of the ventilation system when this vertical-axis wind turbine was implemented.…”

“…Even so, traditional wind turbines have limitations in that they tend to have a negative effect on the ventilation system efficiency and that they are inconvenient to install or mount to the ventilation systems in the limited available area, particularly in urban settings. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Traditional wind turbines need to be installed between 20 and 150 cm away from the wind generator of the ventilation system.…”

The air discharged from ventilation systems is a high potential wind resource for generating electricity in countries where wind speed is unreliable or weak, such as in Thailand. The air discharged from ventilation systems produces consistent and high-speed wind when benchmarked against natural wind. However, the limitations of conventional wind turbines are that they have negative impacts on the ventilation system and are inconvenient to install in many areas. The innovative shaftless horizontal axis wind turbine (SHWT) introduced in this article has been designed to close the gap between the wind source and the conventional wind turbines in this process. The concept design shows how it could be mounted next to sources of waste wind, requiring only a small space for installation. An open hole is provided to enable airflow to be discharged into the environment. This SHWT has high market potential for utilizing man-made wind to generate electricity from an alternative source which supports sustainable energy development. The purpose of this study is to demonstrate the concept design of a prototype SHWT used for energy recovery from the discharged air of a ventilation system. How the rotor and stator design of the SHWT optimize wind turbine performance and minimize the negative effects on the ventilation system efficiency are also addressed in this study. The performance of the SHWT is demonstrated in a lab-scale test using the type of propeller fan that is generally applied in many sectors in Thailand.The results showed that the SHWT was successful in generating electricity and produced minimal negative effects on the ventilation system's performance.The maximum power output of the prototype SHWT is 7.4 W at a rotational

“…Together with this, there are also different applications for small wind turbines, such as lifting water to tanks located high, or pumping it from underground [45]; integrating small wind turbines into buildings, or installing them on the rooftops, especially on high-rise buildings [46]; and even providing electricity to on-grid consumers which will supply its excess to the power system (which are usually referred to as prosumers) [47,48].…”

A Controller for Optimum Electrical Power Extraction from a Small Grid-Interconnected Wind Turbine

Currently, wind power is the fastest-growing means of electricity generation in the world. To obtain the maximum efficiency from the wind energy conversion system, it is important that the control strategy design is carried out in the best possible way. In fact, besides regulating the frequency and output voltage of the electrical signal, these strategies should also extract energy from wind power at the maximum level of efficiency. With advances in micro-controllers and electronic components, the design and implementation of efficient controllers are steadily improving. This paper presents a maximum power point tracking controller scheme for a small wind energy conversion system with a variable speed permanent magnet synchronous generator. With the controller, the system extracts optimum possible power from the wind speed reaching the wind turbine and feeds it to the grid at constant voltage and frequency based on the AC–DC–AC conversion system. A MATLAB/SimPowerSystems environment was used to carry out the simulations of the system. Simulation results were analyzed under variable wind speed and load conditions, exhibiting the performance of the proposed controller. It was observed that the controllers can extract maximum power and regulate the voltage and frequency under such variable conditions. Extensive results are included in the paper.

“…Another form of building integrated wind energy makes use of ducted micro-turbines such as found in Grant and Kelly [118], Grant et al [119] and Park et al [120]. Operating power coefficients of 0.3 have been observed, but it remains unclear how such ducted micro-turbines can benefit dramatically the energy budget of the building especially when one considers operational and installation costs.…”

Urban wind energy research is crucial for the success or failure of wind turbines installed in the built environment. Research in this field is fragmented into various research groups working on different topics in isolation with seemingly few efforts of integrating the various fields. This review aims at highlighting the synergies between the various advances, particularly in aerodynamics, but also in other areas. Past and current work has been focused on establishing reliable wind statistics at the site of interest. Advances in building aerodynamics have provided new insight on the local flow occurring at the rotor location. An outlook toward future research and the need to treat the different flow scales in a holistic manner is emphasized given also the recent advances in rotor aerodynamics related to the effect of flow skewness and turbulence. This will shed light on the critical issues that need to be addressed by scientists in order to make urban wind energy viable for decentralized generation. Various other present challenges are discussed briefly including structural aspects, noise emissions, economics and visual impact. Research in this field should be the guidepost for more targeted certification standards, in an effort to regularize the small wind energy market.
