An event called Recent Trends in Power Grid Monitoring was held at Imperial College in April 2010. New emerging measurement technologies using time-synchronised wide area measurements are essential to manage the operation of power transmission grids in a complex and rapidly changing environment. For instance, the UK grid must adapt by 2020 to bring power from many new wind generation sites to i...

There is a pressing need for Asynchronous Transfer Mode (ATM) traffic measurements to validate/verify a large number of simulation and analytical studies of ATM networks. In this paper, results from a measurement study of traffic on a wide area ATM network, the very High Speed Backbone Network Service (vBNS) network are reported. We illustrate how the traffic characteristics change as the traff...

Embedded systems typically have limited processing and storage capabilities, may only intermittently be powered on. After sending an event upstreams with data from its sensors, the system must therefore able to trust that data, once acknowledged, is not lost. The purpose of this work propose a novel solution for replicating between nodes in such systems, minimal effect on software architecture....

The benefits of composite products are well known to users data from optical sensors: cloud-cleared reflectance or index commonly used as an analysis-ready (ARD) layer. No analogous currently in widespread use that is based on spaceborne radar satellite backscatter signals. Here, we present a methodology produce wide-area ARD images. They build the existing heritage geometrically and radiometri...

This paper describes the experiences, new requirements and prospects of security defense schemes for power systems in China. Adaptive optimal control schemes have served well for 2-3 years to periodically refresh the decision table for preventive control and emergency control to track operating conditions. These schemes are supported by EEAC that is a quantitative method for stability analysis,...
