Ireland is currently striving to achieve an ambitious target of supplying 40% of electricity demand with renewable energy by 2020. With the vast majority of this being met by wind energy, an intermittent and non-dispatchable energy source, it is inevitable that frequent substantial curtailment...

As the installed capacity of wind generation in Ireland continues to increase towards an overall goal of 40% of electricity from renewable sources by 2020, it is inevitable that the frequency of wind curtailment occurrences will increase. Using this otherwise discarded energy by strategically...

Many recent patents worldwide address the concept of harvesting wind energy from aerodynamic losses in motorways, however the mechanics of a specific device dedicated to the task has never been described. The lack of a characterization of the energy resource likely explains why the international...

The collective behavior of wind farms in seven Independent System Operator (ISO) areas has been studied. The generation duration curves for each ISO show that there is no aggregated power for some fraction of time. Aggregation of wind turbines mitigates intermittency to some extent, but in each...

Wind turbine wakes have significant effects on the production efficiency and fatigue loads, and these effects should be considered in the optimization of wind turbine structure and wind farm layouts. In this paper, a numerical model combining Lagrangian dynamic large-eddy models and actuator...

Short duration wind variations affect real time performance of active pitch-regulated wind turbines in two ways as evident from reported experimental and empirical studies. First the mean output power, which may be referred to as the short duration output power, differs significantly from the...

There is considerable interest concerning sustainable, economically competitive and environmentally benign hydrogen production pathways. In this study, a large scale wind-hydrogen plant is assessed for the production of electrolytic hydrogen, for the servicing of the oil sands bitumen upgrading...

In this paper we model the economic feasibility of compressed air energy storage (CAES) to improve wind power integration by means of a profit-maximizing algorithm. The Base Case is a wind park with 100MW of installed capacity and no storage facility. In Variant 1 we add a central CAES system...

Numerical simulation of wake losses is a fundamental step towards the optimization of the exploitation of the renewable wind energy potential especially in off-shore conditions or in coastal areas.

The growing demand for renewable energy with a sustainable and low-energy design is the main topic in many countries. This could indeed influence in utilizing small wind turbines which incorporate innovative designs and new materials of construction which may provide an attractive prospect of...
