PELS Young Professional Webinar: An Investigation into Electric Spring TechnologiesWednesday, March 1, 2017 9:30 AM EST
Presenter: Dr. YAN Shuo, University of Hong Kong
The deployment of renewable energy sources (RESs) could relieve the heavy reliance on fossil fuel for power generation. On the other hand, the increasing penetration of stochastic RESs poses new challenges for the grid. Recent report and survey indicate that when RESs reach a certain level of the total power generation, the stability of the power grid will be interrupted.
Maintaining the balance of power supply and demand is the elemental rule of keeping the grid stable. This task has become increasingly difficult when the share of RESs keeps going up. Supply-side management is one pillar of the solution in taming the intermittency of RESs. Power limiting and droop control are typical examples of supply regulation to provide frequency and voltage support. An alternative approach is to use storage facilities to keep the supply-to-demand balance at the expense of high price and limited capacity.
In smart grids with substantial RESs, traditional control paradigm of “supply following demand” in the grid is gradually being supplemented by “demand following supply”. With a response time in the order of milliseconds, the electric spring (ES) has recently been introduced as a fast automatic demand-supply management (DSM) technology in addressing various stability and power quality issues. This talk provides an investigation into latest development of the ES technology. Aspects of topology, control, and grid application will be covered.
BIO: Dr. YAN Shuo received his B. Eng. at The University of South China in 2007, M. Eng. at Southeast University in 2010, and Ph. D. at The University of Hong Kong in 2016. He is currently a Postdoctoral Research Fellow in the Department of Electrical and Electronic Engineering at The University of Hong Kong. His current research interests include power electronic technology in smart grid, advance control of renewable energy sources, and Microgrid.
Why the More and All Electric Aircraft Needs Power Electronics
Tuesday, March 7, 2017 - 10:00am EST
Presenter: Patrick Wheeler, University of Nottingham
Abstract: There has recently been a major change in the design of aircraft. Electrical systems are being used in applications which have traditionally been powered by hydraulic or pneumatic sources. The Boeing 787 and the Airbus A380 both have significantly larger electrical systems than any previous aircraft. The most important enabling technology for the More Electric Aircraft is been power electronics. Without power conversion none of the benefits of this technology would be possible. However, aerospace applications present some challenging conditions for power electronics and there are still a number of areas where improvements must be made in terms of the weight, volume, cost and reliability of systems. This presentation will introduce the More Electric Aircraft concept and investigate the potential benefits of the technology before considering the challenges our community will have to meet to make the concept of Electric Propulsion of large aircraft possible. The talk will be illustrated with a selection of case studies of systems that have been developed at the University of Nottingham, UK.
REGISTRATION IS COMPLIMENTARY, so please sign up and join us on Tuesday, March 7, 2017 at 10:00am ET.
