The paper presents both a numerical and an experimental approach to study the air flow characteristics of a novel small wind turbine and to predict its performance. The turbine model was generated based on impulse turbine principles in order to be employed in an omni-flow wind energy system in...

This paper presents an energy management strategy to operate a hybrid power system with renewable sources (wind and solar), batteries, and polymeric electrolyte membrane fuel cells. The fuel cells are fed with hydrogen from bioethanol reforming. The energy management strategy uses the concept of...

The growing energy demand, as well as the European policy framework supporting the sustainable development, has strengthened the global interest in wind power installations during the last two decades. The interest is higher in areas with promising natural terrain, such as the Greek islands. The...

The use of a shroud is known to improve performance. In this work, the flow physics and performance of shrouded turbines is assessed by solving the Reynolds Averaged Navier–Stokes equations supplemented with a transition model. Shroud geometries are evaluated for their augmentation of mass...

Recognized as one of the most mature renewable energy technologies, wind energy has been developing rapidly in recent years. Many countries have shown interest in utilizing wind power, but they are concerned about the environmental impacts of the wind farms. The continuous growth of the wind...

Because of the fast rate of wind-energy development it will become a challenge to verify impacts on birdlife and construe ways to minimise these. Birds colliding with wind turbines are generally perceived as one of the major conflict issues for wind-energy development. Development of effective...

European consumers are willing to pay more for “green” electricity, as they highly value renewable energy sources for the contribution to combating climate change. There is a push for getting higher levels of sustainability, leading to a differentiation of Europe‘s electricity market. In...

With 21,136MW of wind energy installed in 2014, India is considered a success story in terms of net installed capacity. Few existing studies on Indian wind energy have highlighted the important role of institutions, and how they stemmed from the work of advocacy groups; studies also tend to...

Wind energy has been the main source of renewable energy in the European Union for the last decade, providing sustainable solutions to the demanding task of replacing conventional energy sources and limiting the environmental damage caused by industries worldwide. While the wind energy field in...

The increase in the cost of traditional sources of energy and the negative environmental effects they cause have made necessary to incentivize the use of renewable energies at the expense of creating a tariff deficit. In Spain, like in the rest of the developed world, Wind Energy is the...
