Manipal Institute of Technology, India
Jayakrishnan Radhakrishnan is a Professor in the Aeronautical Engineering Department at the Manipal Institute of Technology, India. Wind energy conversion systems have been his area of focus for the past seven years. He is also the chair of the Betz Wind Energy Research Center at Manipal University, and the key coordinator for an upcoming startup WindME, that focuses on renewable energy systems for the mass population.
Wind power is one of the most prevalent forms of renewable energy, second to only solar energy. The incumbent idea of extracting kinetic energy from surface wind currents, and converting this energy into electric energy is carried out by the combination of gear drives and an electrical generator. Using a suitable power electronic converter, this electricity may then be integrated into the grid directly, or may also function to supply power to a recharging station. This transition, coupled with the augment of global warming, particularly due to the combustion of fossil fuels to provide electricity, has resulted in multiple small scale installations of wind turbines.
Conventional aerodynamic schemes cannot be applied to rotor blades operating under low Reynolds number conditions as compared to those occurring under high Reynolds number conditions since certain unusual aerodynamic phenomena predominate in the case of the former. This paper entails the design as well as experimental validation of a new class of airfoils for small horizontal axis wind turbines that are used in urban environments.
A common misconception with regard to selection of airfoils followed by subsequent design of rotor blades involves the use of NACA airfoils and other conventional high Reynolds number airfoils. The airfoil is designed in such a way so as to extract the energy from the wind shade region, which is practically unheard of in conventional wind rotor aerodynamics. The aerodynamics as well as the environmental impact have also been studied in depth.

Anna Kowalska-Pyzalska received the M.Sc. degree in management from Wroclaw University of Science and Technology, Wroclaw, Poland in 2001 and the Ph.D. degree in technical science – electrical power systems, from the same University in 2006. Since 2010 she is an assistant professor at Faculty of Computer Science and Management, Department of Operations Research. Anna has an experience in the energy market and economy. Her last papers are devoted to modeling diffusion and adoption of innovative goods in the energy market (e.g. dynamic electricity tariffs) as well as to social acceptance of these goods by the electricity consumers. She is also interested in distributed generation and its integration with the power system. She is a reviewer for JCR listed journals. She participated in realization of a few national or EU grants.
The development of renewable energy sources (RES) created some new possibilities for the electricity consumers. Consumers may now invest in the renewables and produce electricity and heat for their own needs. They may also sell the electricity surplus to the energy supplier. In such a way they may become prosumers. In some countries, the governments and local institutions offer subsidies to encourage consumers to invest in solar panels, photovoltaic, small wind or hydro generators. Such incentives increase consumers’ interest in this sector of the energy market. Moreover, consumers may also choose the energy supplier who offers green electricity tariffs or allows participation in green energy programs. The prospect seems optimistic, but research survey and pilot programs show a very low engagement and enrollment rates among consumers.
This presentation will focus on consumers’ energy behavior and their willingness to pay for RES. Social and psychological factors, that influence the adoption of RES will be discussed. Consumer engagement and acceptance of green energy are necessary to make the diffusion of these products possible and effective. Hence, following questions will be answered:
· How green energy (in particular: green electricity tariffs and small-scale generators) diffuse among the customers;
· What makes consumers adopt to the RES;
· What obstacles slow the diffusion and what factors may enhance the successful adoption;
· What are the main reasons of the intention-behavior gap among electricity consumers.
In conclusion some behavioral strategies that may help to speed up the diffusion of RES among consumers will be proposed.
Currently a retired senior public officer who had assumed the Green Leader role, an integral component of his portfolio within the Ministry of Health (Malta). He participated as representative of the Ministry in several high profile international and European Conferences and Fairs, presenting a Paper Assuming the Green Leader’s Role at Workplace – A Critical Analysis and acted as a moderator in one of the Sessions at the 2nd European Conference & Fair : Education for Sustainable Development – Hamburg (2006). He is also chapter author of the Book Sustainable Economic Development : Green Economy and Green Growth (Springer, 2016).
Since the earliest direct concern for climate change in the Earth Summit, a UN Conference on Environment & Development (UNCED), Rio de Janeiro 1992, this high profile world Organisation has been seeing the writing on the wall…alarm bells of factual and potential global eco degradation and have consistently been spearheading initiatives to translate rhetoric and exhaustive debate into solid and effective commitments to redress the environmental deficiency brought about by over exploitation and abuse of the world’s natural resources and disregard of ecosystems, the lifeline of mankind’s own sustainable survival.
CFCs (now phased out under the Montreal Protocol) and Fossil fuels are making way to less polluting and more sustainable energy sources, reducing deleterious emissions. Heavy industry is progressively shifting to economically and viable alternative sustainable sources of energy from benevolent Mother Nature that has blessed us with unrivalled powers inherent in the Sun, Wind, and Oceans.
Nevertheless, challenges still lie in the way of achieving environmental targets, particularly by under-developed and developing countries which have to cope with climate change adaptation and the extraordinary financial capital to diversify and transform their economies to conform with this new exigency. Other challenges could also be overlooked or underestimated, even in implementing action plans involving renewable energy sources.
This Paper looks at and attempts to analyze, from the perspective of an observant, these challenges and also at viable practical measures to address them in efforts aimed at achieving sustainability based on win-win situations, with a particular focus on the local scenario.

Iran is a rich country in terms of wind energy, however, compared to most countries, little has been done on utilization of renewable energies targeted. Potential energies such as high speed wind tunnels, solar energy, geothermal and valuable biomass sources of energy are at preliminary stages and their share of total power generation is still negligible and does not exceed 0.6%. Whereas, design and construction of wind farms is economically feasible due to reasonable price of equipment and abundance of cheap sources of renewable energy, SWOT analysis is conducted in order to unveil the reasons underlying the slow pace of development of wind farms in Iran. The analysis is intended to draw a roadmap and specify the nation's macro policies.
This SWOT analysis applies in wind farms and reveals the very fact that abundance of inexpensive fossil fuels constitutes one of the most decisive factors why wind farms remain undeveloped in Iran and instead priority is given to the thermal power plants which are both cheaper and more reliable compared to wind power generation. Significant factors considered by private investors and companies in the renewable energy sector, is the economic impediments and governing rules and regulations. In this study, financing procedures and change of law that would facilitate removal of the standing obstacles. The Middle Eastern possess fossil fuel resources but at the same time suffer from shortage of potable water as well as non-development of wind farms. This study in general can be useful and practical in these countries.

The study presents an improved control and operation for a doubly-fed induction generator (DFIG) based stand-alone wind energy system. Since there is no grid supply in stand-alone system, the output voltage has to be controlled in the constant amplitude and frequency even under unbalanced and nonlinear load conditions. This type of loads results in unbalance and distorted stator voltage and current with subsequent power quality degradation and electromagnetic torque pulsations of DFIGs. A new control strategy uses proportional-resonant controllers (PRC) is proposed for compensate the unbalance and harmonic distortion in the stator voltage and current of the DFIG. In this strategy, the load-side converter (LSC) is controlled for the purpose of fully reject the low-order harmonic components and the negative sequence of the stator voltage, this is achieved by employing PRC for the closed loop stator voltage regulation built in the stationary reference frame. As a result, symmetrical and sinusoidal AC voltage is applied to the stator terminal, which indicates that the rotor-side converter (RSC) can be still controlled with the traditional vector control strategy, to keep constant DC-link voltage. Simulation results are given and they show that the proposed control scheme can eliminate stator voltage and current harmonic of stand-alone DFIG effectively.

This study sets out to explore the implications of risks management on renewable energy project delivery, using wind energy projects as an area of interest. One of the major aims of project management is directed towards managing risks and thus an important concept in the field. Despite the progress in wind energy projects, they are subjected to numerous risks throughout their life-cycle. In this study, an exhaustive literature review was done on works of previous researchers complemented by an empirical quantitative survey using online questionnaires. This paper reports not only the critical analysis of the secondary data found in previous literatures, but also the primary data analysis obtained from the online survey. The study found that there is a need for improvement on how risks are communicated within wind project environment. The majority of those who responded to the survey indicated that risk associated factors such as; weather related (66%), economic (44%) and political risk (44%) present significantly impact to wind energy projects in their organizations. Other factors such as technical (26%), construction (36%) and environmental risk (28%) factors were viewed by the respondents as having moderate relevant to wind energy projects. A minority of the respondents (24%) indicated that operational risk associated factors also have minor association to wind farm projects. This finding supports the observation made by the Economist Intelligence Unit that; weather related risk is more significant for wind power projects than for other renewable energy technologies.

The aim of the presentation is to study the cheapest and sustainable way of renewable energy like wind for poverty alleviation in the developing countries of the world-South Asia.
Renewable Energy like wind is the basic need of our life. Look at the universe, no activity is found without the use of energy. You name any action you will find the force of energy behind it. As reported, Renewable Energy like wind, biomass, hydropower and solar are the cheapest source of electricity but the two main problems in the developing nations that is densely population of 5.87 billion amongst the world population of 7.84 billion and concentration on non-renewable energy like fossils, nuclear, coal etc which are very costly and beyond the power of developing nations although a great potential of renewable energy are available. According to World Bank, about 1.4 billon peoples lack electricity in the world and nearly one billion peoples particularly in the developing nations go to bed hungry each night. It means, renewable energy like wind is the main substitute of poverty and stimulates sustainable economic growth, create employment, increase agricultural and industry production as well as decreasing energy crises, which will reduce the poverty in developing nation. As per study, the role of International Energy Agency and International Renewable Energy Agency is very important but sustainability is still a big problem in the production of renewable energy. It is therefore proposed that an independent organization like “International Sustainable Energy Agency (ISEA)” should be established and renewable energy may be commercialized for poverty alleviation on a sustainable way in the developing country of the world-South Asia.

As one of the typical renewable energy sources, wind energy has experienced an immense growth with respect to both the turbine size and the market share, and led to a rapid development of the wind-power equipments. Owing to the highly volatile rough working conditions in real wind farms due to, e.g., wind gust, dust, corrosion and heavy yet unpredictable load, wind turbines are particularly prone to suffer failure and damage. Such damage can lead to a catastrophic failure of the entire wind turbine, and consequently heavy investment and productivity losses. Therefore, wind turbine condition monitoring and diagnosis become crucial. In this presentation, the development status of the wind energy all over the world, particularly in China, is briefly summarized. The research situations of the existing condition monitoring and fault diagnosis methods for the main failure components of wind turbines are then analyzed, such as gearboxes, bearings and blades. Finally, the problems to be solved and new development trend for wind power equipment monitoring and fault diagnosis are discussed.
