With the fast growth in the number and size of installed wind farms (WFs) around the world, optimal wind turbines (WTs) micrositing has become a challenge from both technological and mathematical points of view. An appropriate layout of wind turbines is crucial to obtain adequate performance with respect to the development and operation of the wind power plant during its life span. This work presents a fuzzy genetic algorithm (FGA) for maximizing the economic profitability of the project. The algorithm considers a new WF model including several important factors to the design of the layout. The model consists of wake loss, terrain effect, and economic benefits, which can be calculated by locations of wind turbines. The results demonstrate that the algorithm performs better than genetic algorithm, in terms of maximum values of net annual value of wind power plants and computational burden.

Public participation in decision‑making process is an important function of the process called Environmental Impact Assessment (EIA). The respect for the public right in the participation of environmental impact assessment and the right to information are generally controlled by non‑governmental organizations (NGOs) in cooperation with the Ministry of Environment. The support of public is provided in the cases in which queried entity tries not to give the requested information in the appropriate range. NGOs do not follow how the public is involved in the EIA process, and how the comments are relevant or incorporated and whether the final standpoint is influenced. This standpoint is not monitored by Czech Statistical Office. The article deals with the involvement of the general public in the EIA process of wind power plants in the Czech Republic. In selected regions (Moravskoslezský, Olomoucký, Ústecký and Jihomoravský), not only the quantity but also the relevance of the comments in relation to the outcome of the process are evaluated. The own typology groups of the public (individuals, petitions, self‑government etc.) and also applying comments (noise, nature protection, administrative mistakes etc.) were used for the evaluation. All intentions obtained concurring standpoints in the case of zero or low interest of the public.

The relevance of the study is associated with the need to determine scientifically based principles for the design of wind-powered high-rise buildings. The article analyzes the main climatic parameters affecting the design of wind-powered high-rise buildings. While current research focuses mainly on the technical performance and savings of wind power plants (WPPs), modeling wind energy potential based on the analysis of climatic parameters allows you to optimize design solutions taking into account the influence of the environment. For various stages of the design of the integration of wind turbines into a high-rise building, it is important to take into account the dimensions of climate systems (macro, meso and micro levels), based on the laws operating within certain territorial boundaries. The article discusses the macroclimatic indicators that determine the total energy resource of wind in the region. The influence of the parameters of the mesoclimate on the wind potential has been determined, in accordance with the characteristics of the natural and anthropogenic environment (relief, the presence of forests, proximity to water bodies, urban development). The parameters that clarify the energy potential of the wind at the microclimatic level, taking into account the location of the wind turbine in the building, have been investigated. As a result of the analysis, a diagram of the structure of preliminary modeling of the energy wind potential at various climatic levels in the design of wind turbines in high-rise buildings has been determined.

The paper describes special aspects of using the wind power plants (wind turbines) in the power grid. The paper provides the classification and schematic presentation of AC wind turbines, analyzes the role, place and performance of wind power plants in Smart Grid systems with a large share of renewable energy sources. The authors also reviews a detailed analysis of existing AC wind turbines in this paper. Recommendations are given for how to enhance the wind power plants in smart grids in terms of reliability, and introduce the hardware used in the generation, conversion and interface systems into the existing power grid. After the wind power plants had been put online, the relevance of the Smart Grid concept for existing power grids was obvious. The execution of such projects is assumed to be financially costly, requires careful study, and development of flexible algorithms, but in some cases this may be the only approach. The analysis of using wind turbines shows that the structural configuration of wind power plants can be based on the principles known in the power engineering. The approaches may differ, not fundamentally, but in engineering considerations. it is necessary to point out that the method of controlling dual-power machines is quite comprehensive so that their wide use will face operational problems caused by the lack of highly professional specialists in electric drives. Therefore, it seems advisable to use square-cage asynchronous generators in wide applications. The paper shows that as the renewable energy sources are largely used in power grids, there is an issue of maintaining the power generation at a required level considering the variability of incoming wind energy. This results in the malfunctions in the operation of relay protection devices and emergency control automatics (RP and ECA), and the complicated control. Also, the standards of the CIS countries and regulatory documents miss the requirements for the wind turbine protections, taking into account their specialty causing the inefficient standard protective logic, which does not work correctly in a number of abnormal and emergency operating modes, and especially Smart Grid in power grids.

Power generation for the existing electrical grid is largely based on the combustion of fossil fuels. Global concerns have been raised regarding the environmental sustainability of the system due to life cycle impacts, including land losses from fuel extraction and impacts of combustion emissions. An approach to reduce carbon emissions of fossil fuel-based energy employs the conversion of wind energy to electrical energy. The work presented describes modern wind power plants and provides an environmental assessment of a representative wind park from a life cycle perspective. The empirical analysis uses commercially available data, as well as information from an existing wind power plant. The life cycle assessment (LCA) study for a modern wind farm in the northwestern U.S. found that environmental benefits of avoiding typical electricity production greatly outweigh the impacts due to wind turbine construction and maintenance. Effects of component reliability, varying capacity factors, and energy portfolio are explored.

In this paper, we consider the aerodynamic characteristics of profiles used in rotors of horizontal-axis wind turbines for autonomous street lighting systems. For the analysis of the characteristics, five basic aerodynamic profiles of various types were selected: NACA 0018, CLARK-Y-15, NAVY-N-60, EXPLER 1211, GOE 217. Based on the analysis of the selected profiles, aerodynamic calculations were made, and also a calculation was made the geometrical parameters of the blades of the rotors of wind power plants with their subsequent processing and analysis obtained design data under specified conditions. These conditions were taken on the basis of detailed processing and subsequent analysis of the data obtained on the distribution of the speed of wind flow in various territories of Ukraine. Taking into account the selected power characteristics, various types of wind power plants were analyzed, after which it was decided to use horizontal axial-type wind turbines, as this type of wind power plants has the most suitable characteristics to solve the research problem. With the help of a number of mathematical transformations, dependences of lift coefficients and resistance force were established depending on the angle of attack. It was also necessary to make changes in the angles of the profile in the section of the blade in order to improve the conversion coefficient of the wind flow incident on the blades of the wind power plant. As a result, the calculated values of wind turbine diameters were obtained and analyzed for each existing profile separately, in addition, a comparative analysis of the main energy characteristics of wind energy rotors was carried out, which is clearly represented as a dependence of the power factor and moment ratio depending on the speed ratio. In the course of the analysis, aerodynamic profiles with the best weight and size and energy characteristics, capable of maximizing the use of wind flows that prevail in most of the territory of Ukraine, were identified.

The efficiency of using original highly efficient vertical-axis wind turbines (VA wind turbines) based on N-Darya-Savonius combined rotors (KR) is substantiated for the national parks of southern Russia. Based on experimental studies, the power factor of the original combined rotor with blades having zigzag flaps was first obtained. The maximum values of the power factor of the CR reaches CP = 0.6 exceeding theoretically possible values for horizontal-axis wind power plants CP = 0.59. When working in a wind turbine, there are no emissions of pollutants into the atmosphere, oxygen consumption, thermal pollution, generation of infrasound and noise. VA wind turbines with a power of 1–10 kW, it is advisable to apply for the generation of electric and thermal energy in reserves and national parks.
