This study has a main object to assess the wind potential of the site JBEL HDID to Essaouira. First, we give a brief overview on the current status of wind energy in the world and in Morocco. Initial lines of reflection lead us to develop a methodology for developing a wind farm. The implementation of this methodology will allow us to model the wind in three sites from the region, using data from the wind of the three masts from 10m installed on the region and data from nearby sites. Secondly, Measurements are taken over a one year cycle. Then they are compared with the data winds of a meteorological station chosen for the quality of his correlation with measurements registered during the year, and for which it is possible to back in time as long a period as possible, thus, we'll know by statistical formulas the measures of this year that will be representative of all years in this area. Finally, a comparison between the wind turbines from different manufacturers with various configurations, to make a preliminary design of the park and calculates electrical energy that can be produced by it.

Long distances in the vicinities of railways are not exploited in terms of wind energy. This paper presents a scalable power electronics approach, aimed to harness the wind potential in a railway infrastructure. The key aspect of this proposal relies on both using the wind energy in the location, and the displaced air mass during the movement of a train along the railway, in order to produce electrical energy. Vertical Axis Wind Turbines (VAWT) are used in order to take advantage of the wind power, and widely used and well-known power converter techniques to accomplish the goal, showing MPPT techniques, parallelization of converters and power delivery with a Solid State Transformer (SST). Results are shown according simulations of the whole system, with and without train activity, resulting that 30.6 MWh of the energy could be generated without the train, and the energy generated with the assistance of the train could reach 32.3 MWh a year. Concluding that almost the 10% of the energy could be provided by the assistance of the train.

The use of fossil fuels as an energy source is linked to a series of problems, ranging from the possibility of depletion of these resources to pollution and environmental damage caused by their extraction. In this context, wind energy emerges as a clean, renewable and viable option for electrical energy, which Brazil has a large amount of resources to be explored. In 2020, wind energy surpassed natural gas, becoming the second largest source of electricity in Brazil, previewing to reaching a share of 13.7% of total generation from new enterprises that will come into operation . With this, feasibility studies and computer simulation have become increasingly important to reduce costs associated with prospecting new sites with wind potential. The present work aims to elaborate a technical feasibility analysis and computational simulation of a wind farm in the northern region of Rio de Janeiro. Initially, prospective studies will be carried out to select a suitable location for a possible wind installation. Then, the potential of the chosen location will be evaluated, based on wind data available in the literature, so that the technical feasibility of wind generation can be analyzed. To perform the fluid dynamics simulation, the ANSYS Software will be used, where initially several geometric profiles of helix and helical turbines will be studied to then define the type of mesh that best discretizes the wind turbine. From this work, it is expected to find a location with good wind potential in the northern region of Rio de Janeiro, where there is technical and economic feasibility for the installation of a plant; and verify the behavior of the wind turbine and its arrangement at the selected location

Wind energy usage is increasing at fast rates due to significant technical advances, energy supply security and environmental concerns. Research is focusing among others areas on the development of reliable and accurate wind energy assessment methods. Offshore wind energy resources are usually larger than at geographically nearby onshore sites, which may offset in part higher installation, operation, and maintenance costs. Successful offshore wind energy development relies on accurate analysis and assessment of wind energy resource potential. Offshore wind assessment challenges are related to the wind turbine size, offshore installation challenges, lack of adequate and long-term wind and meteorological measurements, etc. Wind, a highly intermittent phenomenon has large spatiotemporal variability, being subject to sub-hourly, hourly, diurnal, seasonal, yearly, and climate variations in addition to their dependence on the geography and environment. Wind regime characteristics are critical to all aspect of a wind energy project, e.g. potential site identification, economic viability, equipment design, operation, management, or wind farm impacts on the electric grid. For a reliable wind energy assessment, measurements at rotor heights are required at least for one year. If such measurements are not available needs to be substituted by alternative approaches, e.g. measure-correlate-predict or numerical methods. Chapter objectives are to provide the reader with comprehensive reviews of the wind energy assessment and analysis methods.

Implementing renewables in the built environment represents a must, considering the target of Nearly Zero Energy Buildings set by the European legal frame, starting with 2020. One specific feature of the built environment is that it additionally imposes constraints, and can distort the renewable energy potential, particularly the wind energy. Therefore, the development of optimized, efficient small wind turbines requires on-site monitoring and, further on, models developed/adjusted according to these. Thus, the main purpose of this study is the analysis of the available wind potential in the built environment – particularly in the Colina Campus of the Transilvania University, in order to implement small wind energy conversion systems. Wind data are collected during one year (2013) from the meteorological station from Brasov - Ghimbav (located 8 km far from Brasov), and from a second weather station, which is mounted on the rooftop of the university building in Brasov city (University hill). The results indicate that the area has a promising wind potential for the implementation in this built environment of small-sized wind turbines, which can start operating from 0.8 m/s and producing electricity from min. 1.8 m/s.

In conducting the siting analysis of a possible on-shore or off-shore wind farm, computational tools are required to analyze the extensive wind data collected over long periods of time in order to estimate the energy that can be harnessed at that particular location. The major parameters that play a crucial role in this are the wind speed, wind direction, and presence of turbulence in the upcoming wind. However, estimation of the potential for electrical energy generation from wind at a particular site is quite complex and prone to error due to the uncertain nature of the wind. The yaw error, which is the difference between the direction of wind and the normal to the face of the rotor, can reduce the power output of a wind turbine significantly. Zero inertia assumption for the turbine rotor used by multiple assessment tools result in overestimation of the power output. For an accurate estimation of the energy that can be harnessed, the effect of directional change of the wind should be incorporated along with the other obvious parameters such as the wind speed, the effect of landscape and altitude. Most modern utility-scale wind turbines are equipped with yaw motion controller and direction measuring sensors that help change the yaw angle of the wind turbine to adjust for the wind direction. A dynamic control model and the corresponding scheme have to be incorporated in the energy estimation process. A wind energy assessment analysis for a potential off-shore wind farm in Lake Michigan is currently under way. An unmanned marine buoy, equipped with LIDAR-based data acquisition system, is deployed in Lake Michigan and data are measured at six different altitudes starting from 55 m and up to 175 m. As project participants, the authors have been working on developing a versatile, flexible and precise model and software tool to evaluate the potential for electrical energy generation. A MATLAB based program has been developed for this purpose, equipped with the capability of working with different data formats and different time averaged data sets. A dynamic model capable of considering the change in wind direction and adjusting the yaw angle has been developed as a part of the MATLAB program. The dynamic model evaluates the yaw error and implements a scheme for the adjustment of the orientation of the wind turbine in order to provide an accurate estimate of the amount of wind energy that can be converted into electrical energy. The algorithm for this dynamic model and the results obtained are discussed in this paper.

In parallel with the rapid increase in energy consumption today, it is known that conventional energy resources will be exhausted in the near future. Renewable energy sources are becoming more important today with decreasing available fossil resources and increasing energy needs. Wind energy is a clean and renewable energy source and has a remarkable importance. Wind energy is one of the most important renewable energy sources, whose technology and use have developed rapidly and their economy has become competitive with fossil energy sources. The systems that convert the energy in the wind into electrical energy are wind turbines. Wind turbines are classified according to their rotational axes, revolutions, powers, number of wings, wind effect, gear characteristics and installation locations. Energy has become one of the most important problems of the world countries today. Energy demand, as in many countries, is increasing with each passing day in Turkey. For this reason, solutions are sought to provide the energy needed in a timely, sufficient and reliable manner. The energy needed in these solution suggestions should be provided from domestic production opportunities and local energy sources as much as possible. In this study, usability of wind energy is tried to be revealed in Osmaniye province and its surroundings. When the wind map studies in Turkey are examined, in Osmaniye Province it has been found that the presence of wind potential, it is necessary to increase the number of WPP to benefit more from the potential of wind energy.

Wind power is one of the three main renewable energy sources, along with solar and hydropower, which are widely used to produce electricity worldwide. As an energy resource, wind is widespread and can provide electricity to much of the world, but it is both intermittent and unpredictable, making it difficult to rely on wind power alone. However, when used in combination with other types of production or in combination with energy storage, wind can make a valuable contribution to the global energy balance. Over the past few decades, wind power has emerged in a number of countries as a separate energy sector that has successfully competed with conventional energy. Attention is paid to wind power plants (WT) as part of distribution and transmission networks. In this regard, an urgent scientific and technical task is the efficient use of wind potential, which is not only to improve aerodynamic characteristics WT, but also to increase productivity WT as a whole. This article presents the type of wind turbines, among the possible applications and very promising is the wind turbine Bolotov (WRTB), which by its technical characteristics surpasses the traditional propeller and other installations using wind energy in the production of electrical energy. The increase (WEUF - wind energy utilization factor) in all modes of operation WT by improving various methods of automatic control is relevant, and the proposed work is devoted to this issue.

According to the International Energy Agency (IEA-2013), Electricity alone does not create all the conditions for socioeconomic growth, but it is obviously essential to meet basic human needs and facilitate the development of economic activities. For the isolated areas with high wind potential and the island suffering from the electrification problems, the prospective solution is the use of renewable energies, especially wind energy. The present paper deals with a detailed statistical study on wind energy, its parameters, and variables on Socotra Island in Yemen, where that island is isolated from the main electricity grid in addition to the difficulty of providing electrical energy to this region in light of conditions in which Yemen has been living in recent times. The simulation results prove that the mean wind speed can reach a value ranging from 8.36 to 10.36 m/s, which is a large and enough speed to generate electricity using turbine farms. Based on the k and c Weibull parameters, the maximum probability at speeds 3 and 4 m/s is 0,052, while a value of 0,085 at speed 7 m/s is given by Rayleight distribution. Every result proved that Yemen has a good wind energy potential can utilize it for electrical energy production, and that strengthens the planning of economical wind turbines capacity for electricity production in the region.

Remote communities on the outskirts of Trinidad and Tobago have the perennial challenge of a reliable supply of electricity. Frequent outages can have a negative effect on the quality of life for persons in such areas. Manzanilla is one such community. It however lies on the east coast of Trinidad. The east coast is commonly thought to have a significant wind resource compared with other areas of Trinidad. This study looked at the feasibility of providing wind energy to a community in the Manzanilla area. Average power consumption was determined by a survey for a total of almost 300 households, businesses and combined establishments in the area. The wind resource was examined to determine if it could meet the electricity demand which has been growing steadily from 2001 to the present. The wind resource was found to be adequate when compared with similar areas considering the generation of wind energy.
