Trend of the Smart Grid Development

Guest lecturer

Prof. Wei-Jen Lee, Energy Systems Research Center, The University of Texas at Arlington, US


10:00 - 10:55


The electrical power system in the US has been named as "the supreme engineering achievement of the 20th century" by the National Academy of Sciences. While the power system is a technological marvel, it is also reaching the limit of its ability to meet the nation's electricity needs. In addition, our nation is moving into the digital information age that demands higher reliability from the nation's aging electrical delivery system.

The modernization of the electricity infrastructure leads to the concept of “smart grid”. A comprehensive smart grid design should cover both top-down and bottom-up approaches. For the current centralized generation and transmission system, upgrading the power delivery infrastructure, enforcing the system security requirement, and increasing interoperability are well known techniques to improve the reliability and the controllability of the power system. For the bottom-up approach, one of the most important features is its ability to support a more diverse and complex network of energy technologies. Specifically, it will be able to seamlessly integrate an array of locally installed, distributed power sources with smaller CO2 footprint, such as fuel cells, photovoltaic, and wind generation, into the power system.

This presentation discusses the opportunities and challenges for the development of Smart Grid, highlights the smart grid related researches that I have been involved recently, and explores the possibility for future collaborations. The presentation concludes with the listing of issues needed to be addressed to ensure successful integration procedures that will eventually create new structures of efficient, modular and environmentally responsive electricity infrastructure that will have an impact nationally as well as globally.

Estimation and Control of Future Power Grid: Challenges and Opportunities

Guest lecturer

Prof. Bikash Pal, Imperial College London


11:00 - 11:55


Electrical generation, transmission and distribution systems all over the world have entered a period of significant renewal and technological change. There have been phenomenal changes/deployments in technology of generation driven by the worldwide emphasis on energy from wind and solar as a sustainable solution to our energy need.  Increasingly energy demand from heating and transportation will be met by electricity.  So to accommodate changes in either end the transmission grid is required to operate in more responsive manner. This is the most credible challenge in smart transmission grid operation today.  The practice of centralised control has been challenged by communication network and security of large volume of data. The new form of demand has also challenged our traditional approach to demand modelling. Coupled with domestic scale storage and generation – the operation and control of distribution network requires innovation in modelling and control.

This talk will highlight the problems and will provide some insight into the future.  It will then suggest a few possible specific research directions to follow based on relevant technical study conducted at Bikash Pal’s research group at Imperial College London. 

About the lecturer

Bikash Pal holds the Chair of Power Systems at Imperial College London. His research over the past 20 years has focused on designing robust control techniques to guard against power system stability problem. He has led strategic research in power transmission control and state estimation with lasting support from Engineering and Physical Research Council (EPSRC), UK, Council of the European Union and power industries: ABB, UK Power Networks and National Grid, UK. Currently he leads an eight-university UK-India research consortium on Smart Grid and Storage and a six-university UK-China research consortium in Smart Grid and Control. His research group have won President's outstanding research team award at Imperial College London, 2016. He has written two books on power system stability and control, published 75 IEEE/IET journal papers, graduated 18 PhDs and supervised 20 post docs.  He was with the faculty of IIT Kanpur and Jadavpur University before joining Imperial College London in 2001.  Prof Pal’s DLP lectures have benefited many colleagues in power engineering profession worldwide. He has offered course on power system stability and control and on power system protection for practicing engineers from Brazil, Chile, Mexico, Europe, Middle East and India. He is consultant to National Grid UK and ALSTOM Grid UK (now GE Grid Solution UK Ltd), UK Power Networks and STATNET Norway where he provided technical solution to power network stability related problems. He has been approached by the United Nation (Framework for Climate Change) for clean development mechanism programme.   As Editor-in-Chief (2005-2012) of IET Generation, Transmission and Distribution journal, he has demonstrated outstanding leadership in promoting high quality research from our power engineering colleagues. He chairs IEEE PES Working Group on Distribution System State Estimations: Practical Challenges, Limitations of Current Tools and Research Need.   He is Editor-in-Chief of IEEE Transactions on Sustainable Energy. He was honoured by the German Research Foundation (DFG) with Mercator Professorship in 2011. Prof Pal is a Fellow of IEEE for his contribution to power system stability and control. He is also a visiting Professor at Tsinghua University.
