Base-load cycling on a system with significant wind penetration

Troy, Niamh ; Denny, Eleanor ; O'Malley, Mark (IEEE, 2010-05)

Certain developments in the electricity sector may result in suboptimal operation of base-load generating units in countries worldwide. Despite the fact they were not designed to operate in a ﬂexible manner, increasing ...
Building a sustainable energy future : supply and demand options

Denny, Eleanor ; O'Malley, Mark (IEEE, 2008-07)

Fossil fuel depletion and concerns over global climate change are increasing the demand for sustainable and clean solutions for electricity generation. In the coming years some of the most difficult engineering challenges ...
Demand side resource operation on the Irish power system with high wind power penetration

Keane, Andrew ; Tuohy, Aidan ; Meibom, Peter ; Denny, Eleanor ; Flynn, Damian ; Mullane, Alan ; O'Malley, Mark (Elsevier, 2011-05)

The utilisation of demand side resources is set to increase over the coming years with the advent of advanced metering infrastructure, home area networks and the promotion of increased energy eﬃciency. Demand side resources ...
Developments in energy technology and policy research

Denny, Eleanor ; Burke, Daniel J. ; Fitzmaurice, Ronan ; Keane, Andrew ; Nyamdash, Batsaikhan ; Richardson, Peter ; Silke, Emma ; Troy, Niamh ; Tuohy, Aidan ; Twohig, Sonya ; Vittal, Eknath ; O'Malley, Mark (2008-09)
Evaluating which forms of flexibility most effectively reduce base load cycling at large wind penetrations

Troy, Niamh ; Denny, Eleanor ; O'Malley, Mark (Energynautics, 2009-10)

Increasing penetration of wind power on power systems worldwide is resulting in the unconventional operation of base-load generating units. These units which were originally designed for operation at full output are ...
Operating the Irish power system with increased levels of wind power

Tuohy, Aidan ; Denny, Eleanor ; Meibom, Peter ; Barth, Rudiger ; O'Malley, Mark (IEEE, 2008-07)

This paper summarises some of the main impacts of large amounts of wind power installed in the island of Ireland. Using results from various studies performed on this system, it is shown that wind power will impact on ...
A quantitative analysis of the net benefits of grid integrated wind

Denny, Eleanor ; Bryans, Garth ; Fitz Gerald, John ; O'Malley, Mark (IEEE, 2006-06)

Throughout the world significant development is being encouraged in wind energy for electricity generation. A complete cost and benefit analysis has been conducted in this paper on grid connected wind generation. It takes ...
The relationship between base-load generation, start-up costs and generation cycling

Troy, Niamh ; Denny, Eleanor ; O'Malley, Mark (International Association for Energy Economics, 2008-12)

Developments in the electricity sector such as the integration of increasing levels of renewable power, mainly wind, and the deregulation of electricity markets have resulted in some unconventional operation of base-load ...
Rolling unit commitment for systems with significant installed wind capacity

Tuohy, Aidan ; Denny, Eleanor ; O'Malley, Mark (IEEE, 2007-07)

As wind power penetration grows, the amount of reserve needed on the system also grows, due to the increases in the uncertainty of wind power, which grows larger as forecast horizon increases. By scheduling the system more ...
Unit commitment for systems with significant wind penetration

Tuohy, Aidan ; Meibom, Peter ; Denny, Eleanor ; O'Malley, Mark (IEEE, 2009-05)

The stochastic nature of wind alters the unit commitment and dispatch problem. By accounting for this uncertainty when scheduling the system, more robust schedules are produced, which should, on average, reduce expected ...
The viability of balancing wind generation with storage

Feeley, C. ; Bryans, A. G. ; Nyamdash, Batsaikhan ; Denny, Eleanor ; O'Malley, Mark (IEEE, 2008-07)

This paper studies the impact of balancing wind generation with storage on the thermal plant mix and load for different levels of installed wind and storage, and under different operational strategies. Moreover, the ...
