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.

The exploitation of distributed renewable energy sources leads to a low-carbon energy transition, mainly based on the optimal integration of hydro, PV and wind power plants with the remaining high-performance fossil-fuel power stations. In the last twenty years, European Union (EU) countries have shown a significant increase of the power installed in new PV and wind power plants, together with the refurbishment of small and medium size hydro stations. In particular, in Italy, PV and wind energy production has strongly increased and nowadays there are regions characterized by a very green energy mix. In this new scenario, energy storage becomes a viable solution to mitigate the variability of renewable energy sources thus optimizing the network operation. The present paper is focused on the Liguria region, in the North of Italy and in particular on the Bormida Valley where nowadays more than the half of the annual electricity consumption is covered by the renewable energy local production. The paper describes the current energy situation and proposes an optimization tool to investigate the possibility of installing new PV and wind power plants, as well as energy intensive storage units based on sodium-sulphur batteries; moreover, different scenarios are analyzed through the definition of economic and environmental key performance indicators.

The article contains the following technical proposals for the power supply of autonomous agricultural facilities using renewable energy sources: the use of hybrid solar-wind power plants, the use of vortex wind power plants with a vertical axis to use both the energy of horizontal wind flows and the energy of upward air flows. The structure and operation algorithm of an autonomous power supply system based on a hybrid solarwind power plant and a diesel generator for autonomous agricultural facilities of small and medium power in regions where there is no distribution electric network are proposed. This system will allow for insufficient wind load to ensure reliable power supply to an autonomous agricultural facility with minimal use of diesel fuel. The design of a vortex wind power installation has been developed. The fastening on the shaft of the wind power installation of a conical helical blade with a variable radius, decreasing in the direction from the lower to the upper cut of the socket, improves the efficiency of the installation. The proposed installation makes it possible to use small winds and low-potential thermal ascending air currents, reduce low-frequency vibration and noise, and also increase the stability and efficiency of use of wind energy.

According to the Directive 2009/28EC of European Parliament and Council, dated April 23, 2009, Lithuania should strive for the part of renewable energy sources in the balance of electric energy to reach no less than 23% in the year 2020. The most favorable condition for development of wind energy in Lithuania is on a 50 km width zone by the seaside. Parks of wind power plants are expanding fast, but there is a lack of data about noise generated by wind turbines. The noise generated by the wind power plants is known to fluctuate and may spread up to 2 km beyond the wind power park. Research of noise generated by wind power plants was performed in the western part of Lithuania, near Rudaiciai village (Kretinga district) at the park of four wind power plants. Measurements were performed in cold and warm seasons when different wind speed, environment humidity and air temperatures dominated. The sound pressure levels of noise generated by wind power plants were established. The noise spread in the wind parks and beyond was evaluated according to hygiene norm HN 33:2007 “Acoustic noise. Noise value limits in the residential and public buildings and their surroundings”. Santrauka Remiantis Europos Sajungos Parlamento ir Tarybos 2009 m. balandžio 23 d. direktyva 2009/28/EB Lietuva turi siekti, kad 2020 m. atsinaujinančiųjų energijos išteklių dalis šalies elektros energijos balanse sudarytų ne mažiau kaip 23%. Lietuvoje vėjo energetikai plėtoti palankiausios sąlygos yra maždaug 50 km pločio juosta prie jūros pakrantės. Sparčiai plečiantis vėjo jėgainių parkams trūksta duomenų apie vėjo jėgainių skleidžiamą triukšmą. Žinoma, kad triukšmas nuo vėjo jėgainių yra fliuktuojantis bei gali sklisti iki 2 km už vėjo jėgainių parko ribų. Vėjo jėgainių skleidžiamo triukšmo tyrimai buvo atliekami vakarų Lietuvoje, Rūdaičių k. (Kretingos r.) prieigose esančiame keturių vėjo jėgainių parke. Atlikti žiemos ir vasaros matavimai, vyraujant skirtingiems vėjo greičiams, aplin-kos oro drėgniui, oro temperatūrai. Nustatyti vėjo jėgainių parko skleidžiamo triukšmo, garso slėgio lygiai. Pagal higienos normą HN 33:2007 ,,Akustinis triukšmas. Triukšmo ribiniai dydžiai gyvenamuosiuose ir visuomeninės paskirties pastatuose bei jų aplinkoje“ įvertinta triukšmo sklaida vėjo jėgainių pake ir už jo ribų. Резюме На основании Директивы 2009/28/УС, принятой 23 апреля 2009 г. Парламентом и Советом Евросоюза, Литвадолжна стремиться к тому, чтобы к 2020 г. часть возобновляемых источников энергии в электроэнергетическомбалансе страны составляла по крайней мере 23%. В Литве наиболее благоприятные условия для полученияветряной энергии могут быть созданы на полосе шириной примерно в 50 км вдоль зоны морского побережъя. Всвязи с интенсивным развитием парков ветряных установок данных о создаваемом ими шуме не достаточно.Известно, что шум от ветряных турбин флуктирует и может распространяться до 2 км за пределы парковветряных установок. Исследования четырех ветряных турбин и создаваемого ими шума проводились в парке ветряных установок наЗападе Литвы, в Рудайчяй (Кретингский район). Измерения проводились зимой и летом при разной скорости ветра, влажности и температуре воздуха. Установлены уровни распространяемого ветряными установками шумаи звукового давления. На основании гигиенической нормы HN 33:2007 «Акустический шум. Предельныевеличины шума для жилых зданий, зданий общественного назначения и их среды» установлено распространениешума в парке ветряных установок и за его пределами.

In modern conditions of falling business activity of enterprises and falling incomes of the population, the growing trend of electricity shortages persists. This need may be aggravated by the high level of deterioration of equipment at Russian thermal power plants. All world practice shifts the guidelines for expanding electricity production towards the creation of a market for pre-fabricated renewable energy sources. In the article, the authors focused on justifying the need for the massive construction of wind power plants as an alternative source of energy. Today, «traditional» energy sources cannot meet the growing demand in remote areas of the Tyumen region with districts in the context of the spread of modern information technologies and the process of digitalization of public services. The current situation also imposes significant restrictions on the intensity of the development of the process of educational technologies in remote settlements. In this connection, the authors of the article decided to conduct an analytical study to substantiate the ways of territorial development through the launch of projects for the construction of compact wind power plants as an alternative source of energy in providing resources to remote settlements.

Favorable Conditions

Techno-economic indicators of renewable (solar and wind) and non-renewable energy sources are systematized, taking into account the interval of their uncertainty for the conditions of the countries of the Commonwealth of Independent States (CIS). The main attention was paid to Russia and the countries of Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan), where there are the most favorable conditions for the development of solar and wind energy. A comparison of renewable and non-renewable energy sources by the criterion of the cost of generated electricity has been made. It is shown that the payment for greenhouse gas emissions increases the competitiveness of solar and wind power plants in the energy markets. Under favorable conditions for renewable energy, solar and wind installations in some areas can produce cheap electricity at a cost of 3–5 cents/(kW×h). With such values, they can be competitive without additional measures to stimulate their implementation. Using the mathematical model REM-2 (Renewable Energy Model), energy sources of different types were compared taking into account system effects. The power supply system consists of photovoltaic converters, wind turbines that enable the possibility of short-term accumulation of electricity and power consumption from a backup power source. Modeling of photoelectric converters and wind turbines operating modes was performed by time (hours) for different values of solar radiation arrival and wind speed. The optimal ratios between electricity production by photovoltaic converters and wind turbines, as well as the optimal level of electricity consumption from the network under different climatic and economic conditions, were determined. The economic efficiency of joint use of solar and wind energy in the CIS countries, primarily in Russia (with the exception of the northern regions) and the countries of Central Asia, is shown.

Supply Interruptions

In the conditions of regions with relatively low solar and wind potentials, interruptions in power supply to consumers powered by micro-power plants based on renewable energy sources may be due to a decrease in the power of wind power plants, photovoltaic modules with insufficient wind speed and insolation, respectively, to provide power to consumers. A study of the reliability of a system including a wind power plant, photovoltaic modules, a hybrid charge controller, an energy storage device and an inverter was carried out using a logical-probabilistic method. As part of the study, an analysis was made of the structure of the power supply system and its modes of operation in the event of various events: failure of system elements, replacement of failed elements, diagnostics of elements, decrease in the power of the wind power plant and photovoltaic modules. Combinations of events leading to a power failure of consumers connected to a hybrid micro-power plant have been determined. A fault tree was built for the hybrid micro-power plant. Expressions are obtained for calculating the probability of short-term, long-term power supply interruptions, the probability of power supply interruptions occurring when off-design insolation and wind speed occur. Mathematical modeling of the reliability of the hybrid micro-power plant for the conditions of the central part of the Republic of Mari El has been carried out. It has been determined that the probability of a system failure is determined mainly by the probability of long power outages. In this case, the reliability indicators of the system as a whole are largely determined by the values of the reliability indicators of the hybrid controller and inverter.
