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 ...
Minimum cost curtailment for distributed generation voltage management

Keane, Andrew ; Zhou, Qiong ; Bialek, Janusz W. ; O'Malley, Mark (2008-07)

The penetration of DG is increasing on distribution networks across the world. As a result, networks are being pushed closer to their operating limits. In particular, voltage rise has been identified as a key barrier ...
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 ...
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 ...
