[2017] Invited external supervisor of Kathmandu University, in Nepal
I was supervisor of Mr. Ravi Raj Shrestha, a graduate student of Master of Engineering in Electrical Power Engineering (MEEPE) cohort 2015-2017, at Department of Electrical and Electronics Engineering in Kathmandu University, Nepal to defend his dissertation titled " Impact of Distributed Generation on Protection Coordination".
[2010] The HVDC Doctoral Colloquium | www.fe.up.pt/~hvdc
This colloquium allows researchers and PhD students to discuss the research they are doing in the fields of HVDC transmission and integration of large offshore wind power. The colloquium includes topics on HVDC circuits, power converter topologies, multi-terminal HVDC, DC grids, power flow analysis, protection schemes, operation and control and scaled laboratory experiences.
Summary
The HVDC doctoral colloquium was initiated by Professor Nicholas Jenkins, from University of Cardiff, UK and Dr. Oriol Gomes from CITCEA-UPC Centre of Technological Innovation in Static Converters and Drives Electrical Engineering Department, Technical University of Catalonia and myself. This colloquium lasts for 1.5 day with a half day reserved for the topic of microgrid.
This doctoral colloquium serves as a platform for young researchers to exchange their knowledge, share ideas and disseminate findings in the topic of HVDC, with an objective to better understand the subject and to inspire critical insight. They will be given feedbacks by Professor Nicholas Jenkins and Dr. Gomes, world-class researchers in this area.
This colloquium aims to further widening the community in the following years, by inviting more passionate academics around the world as well as industrial practitioners keen to advance the subject knowledge and its application.

The 1st HVDC Doctoral Colloquium was hosted by INESC TEC/University of Porto, Portugal and organised by myself. In 2011 it was hosted by CITCEA-UPCwww.citcea.upc.edu/IIHVDC; in 2012 by the University of Cardiff, UK; and in 2013 by University of Leuven , Belgium - www.hvdc-colloquium.be. Subsequently, the colloquium was organizes in Denmark and Cardiff University and it has been happening ever since.
As a result of this colloquium organized by university of Porto in 2010, a few universities gather together every year, allowing their PhD candidates to meet up with other colleagues and academics from others universities in a more informal way and having more time to discuss their research topics and research routes and ideas. This annual meetings also allows not to overlapping research topics across Europeans universities, institutes and industries but complementary research topics.
Few European research grants have been awarded to this group. See “projects & awards”.
[2010] Business & Innovation Network @ University of Porto
I chaired a session of BIN@FEUP on the subject of micro wind generation. More than 40 attendants were from either the academia or the industry.
Title: “Micro-wind generation: a domestic business opportunity?”
Summary
Summary: The micro-wind turbines are becoming more affordable, attractive and silent. The design became well-suited to residential houses, business, and many other applications. Micro-wind generation can reduce energy bills, carbon footprint and improve the building energy rating.
Can I put a turbine in my garden or on the roof of my house? What are the current regulations regarding domestic development?
What are the attitudes of customers / end-users towards wind turbine? Would they be acceptable to have turbines at home? Is there any safety issues when having a turbine at home? Why should customers be motivated to install a turbine at home? How should we promote this concept?
It is worthy to think about wind micro generation in urban areas? Does it restrict to houses with gardens and/or penthouses?
Is micro-wind generation a cost-effective way of producing energy? what are the expected years of pay-back the investment?
What is the potential of wind micro-generation in Portugal?
Does the actual feed-in tariffs help micro-generation developers to promote their wind micro-generation?
What do entrepreneurs such as windpower; proven energy; Nothern power; entegrity wind systems; bergey wind power think about the future?
What are the costs to maintain the main wind-turbine? Does vertical axis or horizontal axis turbine have lower maintenance costs?
[2011] Business & Innovation Network @ Sheffield University
I chaired a session of BIN@Sheffield, UK on the subject of Offshore Wind Generation. More than 50 attendants were from either the academia or the industry.
Title: “Offshore Wind Generation”
Summary
Summary: With the increased concerns over global warming and means to reduce dependency on imported fuels while fulfilling increased growth of demand, many governments around the globe are imposing targets for the electrical energy derived from renewables. It is expected that most of which will come from wind. By the end of 2009, worldwide onshore and offshore wind capacity was stood around 160 GW and it was expected that it would rise to 200 GW by the end of 2010. Further, the offshore wind power capacity was increasing exponentially and would rise from just over 3 GW today to 75 GW by 2020. This massive growth of offshore wind brings many technical, economical and general concerns. Some of these include:
- Is wind energy generation cost-effective? Can it sustained without providing subsidies from tax payers’ money?
- Is offshore energy a clean, efficient and environmental friendly way of producing energy?
- Can we rely on offshore wind energy?
- Is our Grid ready to receive a significant increment of offshore wind power? Or do we need more Grid investments?
