“…In other words, there is no solution that can ensure the optimal economic cost and environmental protection at the same time, so they can only be compromised and coordinated. The process of solving the multiobjective optimization problem is to find a set of decision vectors that meet the noninferiority and constraints of all objective functions and the set of corresponding objective function values, that is, the optimal solution of economic benefits, so that the decision maker can determine the acceptable decision-making state and corresponding objective function values according to the utility function or preference [ 7 – 9 ]. The economic decision making of wind power generation based on deep learning is the basis and basis to guide safety activities.…”

Wind is a renewable energy source. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind and solar energy provide public health and environmental benefits to the social. Wind turbines may also reduce the amount of electricity generation from fossil fuels, which results in lower total air pollution and carbon dioxide emissions. In order to better optimize the effect of social energy economic management and facilitate the multiobjective decision making of coordinated development of energy and socioeconomic environment, a modeling and analysis method of economic benefits of wind power generation based on deep learning is proposed. In this paper, based on the principle of deep learning, the evaluation indicators of wind power economic benefits are excavated, a scientific and reasonable economic benefit evaluation system is constructed, a wind power economic benefit analysis model supported by public management is constructed, and the steps of wind power economic benefit analysis are simplified. It is concluded that the modeling and analysis method of wind power economic benefits based on deep learning has high practicability in the actual application process, which is convenient for the prediction and analysis of energy demand for social and economic development.

“…The papers contained information on the wind flow in unstructured fields such as buildings, air exhaust, sunroofs, etc. [47][48][49][50], where the main focus was to obtain efficient flow. The most common application was in wind turbines, with the aim of optimizing power output by increasing the airflow.…”

Recent Development in the Design of Wind Deflectors for Vertical Axis Wind Turbine: A Review

et al. 2021

Developments in the design of wind turbines with augmentation are advancing around the globe with the goal of generating electricity close to the user in built-up areas. This is certain to help lessen the power generation load as well as distribution and transmission network costs by reducing the distance between the user and the power source. The main objectives driving the development and advancement of vertical-axis wind turbines are increasing the power coefficient and the torque coefficient by optimizing the upstream wind striking on the rotor blades. Unlike horizontal-axis wind turbines, vertical axis turbines generate not only positive torque but also negative torque during operation. The negative torque generated by the returning blade is a key issue for vertical-axis wind turbines (VAWTs) that is counterproductive. Installation of wind deflectors for flow augmentation helps to reduce the negative torque generated by the returning blades as well as enhance the positive torque by creating a diversion in the upstream wind towards the forwarding blade during operation. This paper reviews various designs, experiments, and CFD simulations of wind deflectors reported to date. Optimization techniques for VAWTs incorporating wind deflectors are discussed in detail. The main focus of the review was on the installation position and orientation of the deflectors and their potential contribution to increasing the power coefficient. Topics for future study are suggested in the conclusion section of the paper.

“…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
