The energy trilemma (energy security, environmental impact and social cost) present various complex interconnected challenges. These challenges extend throughout the UK and have a significant international bearing.  There is vast diversity in challenges faced regionally due to historical, geographic, political, economic and cultural reasons. As technology and society change so do these challenges.  Therefore energy networks planning, design and operation need to adapt.

Whole-systems approach to energy networks research is not considered the norm. Comprehensive knowledge of the interconnected and interdependent nature of energy network infrastructure is simply not available.  The recent development of local energy systems and global energy internet bring further uncertainties and challenges to the development of our energy systems.

Currently, there is a lack of:

  • modelling experience and skills
  • replicable models
  • commercial software
  • awareness of the value of integrated multi-energy networks in the UK.

To better understand the relationships among different energy vector networks, ICT, policy, markets, and risk need to shape future energy development.  Through understanding how external factors may lead to significant changes in the way energy networks behave, we can plan and operate accordingly.

To address the issues above the EPSRC Supergen Energy Networks Hub and the INCOSE UK Energy Systems Interest Group hosted a joint workshop to investigate modelling for Integrated Multi-Energy Networks.  The workshop on the 12th April saw 31 invited participants from academia, government, industry and independent organisations come together to share current best practices in multi-energy system modelling and to discuss how to tackle the barriers and identify innovation gaps.

The first session of the workshop, chaired by Prof Jianzhong Wu from Cardiff University, was devoted to sharing experiences and practices of modelling.  It provided an insight into the challenges of modelling complex systems while giving examples of new tools, models and projects.   There were several interesting presentations by:

  • BEIS (Dr Noramalina Mansor, top left photo),
  • Energy Systems Catapult (Dr David Wyatt, bottom right),
  • West and Wales Utilities (Mr Chris Clark, top right photo), and

academia (Prof Mark Barret, UCL; Prof. Goran Strbac, bottom left photo, Imperial College London; Dr Sara Walker, Newcastle University and Dr Meysam Qadrdan, Cardiff University).

The second session considered how to tackle some of the pressing challenges, difficulties and uncertainties faced by energy systems modellers and the wider community. This session helped to identify research gaps, questions and potential research topics within energy networks.

There were lots of open discussions led by Professor Phil Taylor, Director of the Supergen Energy Networks Hub on how to move forward in terms of research and practice within energy networks modelling.

The suggestions were to focus on demonstration projects, modelling of extreme events as well as the design of simpler but interconnected models among other things.  Moving forward, the participants expressed an interest in another set of such workshops, with a focus on balancing the needs of the local and national systems.

Since joining The University of Manchester, I have been collaborating with a number of Chinese academic institutions, including Shandong University, Tsinghua University, North China Electric Power University and Tianjin University. This has resulted in a number of collaborative activities relating to future Smart Grid solutions and implementation of novel ICT and sensor technology.

As a Visiting Professor at the Shandong University I lead a research team involving both Professors and PhD students. Jointly with the Tsinghua University, I support their research on power system protection and control.

Since 2017, I have attended several high impact events organised by Chinese partners and related to multi-energy networks. I will briefly update you about them in the following text.


The 1st and the 2nd IEEE Conference on Energy Internet and Energy System Integration, Beijing, China

The 1st conference was held in December 2017, whereas the 2nd conference was held in October 2018. Both events were held in Beijing.

The conference focuses on innovative technologies and practical implementations around “Energy Internet” and “Energy System Integration” (EI2). These can be interpreted as the fusion of energy systems with information technologies and artificial intelligence, as well as, the coupling of multiple energy systems (e.g., heating, cooling, electricity, gas, and transportation). This conference promotes innovative EI2 technologies and practical applications which aim to fully realize the interconnection, openness, sharing, and collaboration of various energy resources, and to create green, low-carbon, high-efficiency and low-cost smart energy systems.

The conference has offered opportunities to share experience on a number of topics and I was privileged to meet two of my respected colleagues, who are currently acting Editors in Chief of the hey(? Need to check this with VT) journals relevant for our profession: Prof Nikos Hatziargyriou (IEEE Transactions on Power Systems) and Prof Jianhui Wang (IEEE Trans on Smart Grid). We exchanged our experiences in leading our international journals and discussed how to incorporate, in our journals, results relevant to multi-energy systems/networks.


GEI Panel Discussion on 26th September 2018 in Jinan, Shandong Province, China

A Global Energy Interconnection (GEI) panel discussion was held as a part of a more general Forum, attended by the leading Chinese and international authorities interested in future challenges of energy related industries.

GEI is a clean energy-dominant, electric-centric modern energy system that is globally interconnected, jointly constructed and mutually beneficial to all. It is an important platform for large-scale development, transmission and consumption of clean energy resources worldwide. In essence, GEI is “Smart Grid + UHV Grid + Clean Energy”.

The panel has been moderated by Sr Michel Sterling and discussed the following two questions:

Question 1: Based on your own special fields and experience, could you please share with us your thoughts on how universities, research institutions and international organizations shall play their respective advantages to promote the innovation development of GEI?

Question 2: Could you forecast what unprecedented opportunities will GEI bring, and what kind of cooperation mechanism shall be established as institutional support, so as to guide all parties to participate in the development of GEI?

As one of panellists, I tried to address those issues linking strategies relevant to academia, industry and global society. In this context, I elaborated the concept in which the benefits for the global society should be enabled through joint collaborative work between industry and academia. This collaboration should be fair, open and honest. Industry can help academia to shape the directions of the university research activities, putting to the top of agenda the interest of the society we are leaving in. A typical example are efforts towards reduction of CO2 emission, or optimal operation of multi-energy systems. I particularly discussed the advantages of integration of massive power systems across the globe. In my address, I just reminded the respected audience that e.g. when it comes to solar energy, it is always somewhere available and could be used anywhere in the World, or stored locally, or somewhere remotely.

From the perspective of the cooperation mechanisms, I insisted on the collaboration in which younger researchers, creative and ambitious to contribute to new and high quality innovation, should be particularly involved at all spheres of the collaboration.


December 2018 Gathering with the Premier of China at the Great Hall of the People, Beijing, China

This event focused on the global challenges of Chinese Government in terms of the selection of an appropriate strategy on how to move forward (move forward with what?). The host of the event was the Premier of the State Council of the People’s Republic of China, Mr Keqiang Li. Three Nobel Prize Laureates gave their personal views about the future technological and societal development of China. One of them was Prof Kostya Novoselov (The University of Manchester). In his address, an interesting and exciting information about the future role of “smart materials” opened very vibrant discussions, leading to conclusions that a number of new opportunities for future collaboration are indeed very obvious.

The conclusion is that instead of insisting on the “speed of technological development” the focus should be on the “quality of this development”. This is also directly tackling movements in the sphere of energy systems and networks. Their future development should include attributes like “high quality standards”, “high quality solutions” etc. Just putting the speed of the development to the top of the agenda, might lead to sub-optimal solutions and not the top quality of the innovation. My personal impression was that the planned research activities within our Supergen Energy Networks Hub indeed insist on the quality research, instead on the quantity of results and uncontrolled rush towards scheduled targets

More information of the event and videos of the discussions is available online.

In conclusion, the activities related to Energy Networks development in China is very intensive and the Supergen Energy Networks Hub look forward to collaborating with the above mentioned Chinese partners.

Equality, Diversity and Inclusion in Engineering

I recently attended and event called ‘Data Driven Culture Change’ at the Royal Academy of Engineering where the startling results of an industry survey showed:

  • 11% of surveyed companies had a generic EDI Policy, and 1% has a specific EDI Plan
  • 4% of surveyed companies had some way of measuring EDI
  • 42% of surveyed companies planned general activities around diversity and inclusion.

That means those activities typically aren’t aligned to any strategic plan and the impact of activities aren’t being measured, in the majority of cases.

The Royal Academy of Engineering has a vision to address the engineering skills and diversity challenge. The scale of the diversity issue is being reported more frequently in the mainstream press, particularly recently with the gender pay gap reporting hitting headlines:

Across the energy sector, Powerful Women report a similarly disappointing picture for the top 80 energy companies.

  • Women occupy only 13% of board seats
  • Women make up 6% of executive board seats
  • 86% have no female Executive Director
  • Half have no women on their Board

The Supergen Energy Networks Hub wishes to better understand EDI for the community, to develop and implement good practice in EDI in the way we engage with the community, and to create a sense of belonging for all regardless of background.


Well firstly because it is the right thing to do. Discrimination is not something we wish to support. We intend to engage widely in a way which is inclusive to all.

And secondly, because it is good for research.  Diverse teams outperform homogenous teams for creativity and innovation, which is just what we are looking for in order to tackle the thorny issue of future energy networks.

Thirdly, it makes business sense.  There is strong evidence that diversity in the workplace results in better financial performance (Powerful Women report companies in the top quartile for gender diversity outperform those in the bottom quartile by 35%).

Our approach to EDI for the Supergen Energy Networks Hub is:

  1. To initially audit EDI statistics of the community who we engage with
  2. To ask the community where their needs lie with regards to EDI
  3. To investigate and implement best practice in our own activities around events, recruitment, flexible funding and the many other ways in which we interact with our community
  4. To agree an action plan for the 4 year duration of the Hub.
  5. To continually monitor EDI, to evaluate the impact of the Action Plan, and to update it as required.
