We verify and examine criticality in a 1000 bus network with an AC blackout model that represents many of the interactions that occur in cascading failure. At the critical loading there is a sharp rise in the mean blackout size and a power law probability distribution of blackout size that indicates a significant risk of large blackouts.
The paper discusses our experience in developing and using an innovative tool for electrical design of large offshore wind farms. The tool can be used for a semi-automated design of the inter array cable system, cable sizing/checking, voltage/reactive power control, calculation of electrical losses, energy constrained due to equipment forced outages and the… (More)
A smart software tool for the automated design and cost-benefit analysis of an offshore grid has been developed through a collaboration of Siemens PTI in the United Kingdom and the University of Manchester. Previous work in this area has clearly shown that the number of design options to be taken into consideration, even for a single offshore wind farm, may… (More)
