• Stochastic power system operation 

  Power, Michael (2010)

  This paper outlines how to economically and reliably operate a power system with high levels of renewable generation which are stochastic in nature. It outlines the challenges for system operators, and suggests tools and ...
• 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 ...
• A small - signal stability analysis of DFIG wind generation 

  Vittal, Eknath ; O'Malley, Mark ; Keane, Andrew (Energynautics, 2009-10)

  This paper examines the small-signal stability impacts of high penetrations of doubly-fed induction generator (DFIG) wind turbines on power systems. It provides a basic overview of small-signal stability concepts and then ...
• Boundary-controlled travelling and standing waves in cascaded lumped systems 

  O'Connor, William ; Zhu, Ming (Elsevier, 2012-03-15)

  This paper describes how pure travelling waves in cascaded, lumped, uniform, mass-spring systems can be defined, established, and maintained, by controlling two boundary actuators, one at each end. In most cases the ...
• Wave-like modelling of cascaded, lumped, flexible systems with an arbitrarily moving boundary 

  O'Connor, William (Elsevier, 2011-06-20)

  This paper considers cascaded, lumped, flexible systems, which may be short and non-uniform, which are driven by an arbitrarily moving boundary. Such systems exhibit vaguely wavelike behaviour yet defy classical wave ...
• Boundary-controlled travelling and standing waves in cascaded lumped systems 

  O'Connor, William ; Zhu, Ming (Elsevier, 2012-05)

  This paper shows how pure travelling waves in cascaded, lumped, uniform, mass-spring systems can be defined, established, and maintained, by controlling two boundary actuators, one at each end. In most cases the control ...
• Dynamic frequency control with increasing wind generation 

  Lalor, Gillian ; Ritchie, Julia ; Rourke, Shane ; Flynn, Damian ; O'Malley, Mark (IEEE, 2004-06-10)

  Frequency control is essential for the secure and stable operation of a power system. With wind penetration increasing rapidly in many power systems, ensuring continuous power system security is vital. The frequency ...
