Moving Towards Future
Electrical Systems: Multi-Terminal HVDC + Wind Power
25-28th November 2013
University of Seville
Seville Spain
Looking beyond 2030,
the challenges for electricity networks are likely
to increase. There exists general consensus that the
challenges of climate change, economic development
and system security.
The ability to
accommodate significant volumes of decentralised and
renewable generation, require that the network
infrastructure must be upgraded to enable smart
operation.
The future
electricity networks and its potential issues
require looking beyond the existing research
frontiers irrespective of the disciplinary
boundaries.
The objective of this
seminar is to present the fundamental aspects about
system frequency control and inertia response
schemes for the future electrical systems.
Dr Gonzalez-Longatt
is very pleased to present this seminar in
University of Seville Spain, 25-28 November 2013..
