Masterclass DC Grid

Moderator of this masterclass is Dr. Peter van Duijsen

There’s a lot of talking about DC grids, but what is it? What are the pros and cons? What about the losses? How do you control the power in a DC grid? These are all questions you can easily answer with basic calculations.

In this workshop we will look at the possibilities of a DC grid and you can interactively calculate on your phone, tablet or laptop. We will look at voltage losses over a cable and calculate the difference between DC and AC. How to divide the power in a DC grid by just varying the voltage on the grid. What is really Droop control and how can you visualize it by means of simple resistor networks! How does a Grid-tied inverter work and what do I do with the generated solar energy in my DC grid, store or return it to the grid? Harmonics and grounding? Short-circuit and touch guard, how is that implemented?
These are all issues for which we can find a solution with the help of calculation tools in the cloud, so take your phone, tablet or laptop with you!
Content masterclass DC grid:

  • Difference AC and DC grid,
  • Cable calculation / losses in cable,
  • Power distribution in DC grid,
  • Droop control,
  • Connection AC-DC via AFE, calculation of voltages, currents, power,
  • Storage in batteries,
  • Influence solar energy generation.

Masterclass Planning battery autonomy for large UPS

The moderator of this Masterclass is prof. Ian F Bitterlin

A second masterclass on batteries is in preparation. The theme is “How many minutes autonomy should we plan for?”.

The masterclass subject matter explores the history, the present and future requirements and the paranoia of data centre UPS autonomy.
In particular we will explore partial load versus autonomy time (Peukerts Factor).


  • Reviewing historical development of data centre autonomy from 1956 to 2020.
  • The specific need for autonomy in the 2020’s?
  • The available energy storage technologies and why some have commercially failed?
  • The cause and effect of partial load in the data centre on the battery autonomy.
  • Focusing on electrochemical cells and the progression from flooded Lead Acid to VRLA.
  • What are the real reasons for considering Lithium-ion?
  • Suggestions as to how to design a reliable data centre energy storage battery.
  • Audience questions and comments (10…15 minutes).

Poster Presentation

This year, during the INTELEC95 Energy Symposium 2020, students and PhD students will have the opportunity to present their work via posters. In this way they can share their experiences with speakers, exhibitors and visitors of the symposium. The posters will be visible to all participants throughout the symposium.
A short time is scheduled for a presentation of the poster and authors. It is a challenge to give this presentation in 1 minute (One-minute pitch). During the breaks you will be approached by participants with questions and suggestions.
Every bachelor student, master student or doctoral student who thinks his or her research is interesting to present with a poster can participate in this session.
The best poster will be reviewed by a jury and rewarded with a prize.

At least the following information must be provided: a (working) title and a short summary of the content.
The poster and summary will be mentioned on the website. Deadline for application is Sunday 29 March 2020. For questions:

  • Posters will be presented on display boards.
  • The posters must be delivered in A0 format (841 mm x 1189 mm).
  • Demonstrations by an experimental setups are welcome, but must be registered in advance.
  • The posters must be prepared and assembled in portrait format.

Students who present a poster can participate free of charge in the day programme (including lunch and drinks) of the symposium (see further Registration). Registration is done by submitting an abstract to


Maarten van Andel

(Keynote Speaker)

Title: De Groen Illusie

We hebben een klimaatakkoord, maar de energietransitie wordt beheerst door opportunistische politici en ondernemers. Hoog tijd om feiten van fictie te onderscheiden en na te gaan of elektrische auto’s en aardgasloze huizen wel echt bijdragen aan CO2 reductie. Elke energieoptie, van steenkool tot biomassa, heeft voor- en nadelen. Het vergt natuurwetenschappelijk inzicht om deze in kaart te brengen en verstandige keuzes voor de toekomst te maken. Verder verdient de belangrijkste invloedsfactor veel meer aandacht: Ons eigen gedrag. Maarten van Andel studeerde scheikunde, werkte 32 jaar in het hightech bedrijfsleven en is momenteel directeur bij Fontys Hogescholen. Als auteur van De Groene Illusie zet hij feiten en fictie van duurzame energie overzichtelijk op een rijtje, en legt hij uit hoe wijzelf het beste kunnen bijdragen aan de klimaatdoelstellingen

Ton van Wingerden

Title: Waterstof, noodzakelijk voor de energietransitie

Ton van Wingerden werkt als principal consultant bij DNV GL. De belangrijkste onderwerpen waar hij zich mee bezig houdt zijn asset management en waterstof.

Pavol Bauer

Title: Roadmap for DC

DC grids are considered to be a key technology for the connection, collection and integration of renewable energy resources, for the realization of integrated power systems, for mobile applications (electric ships, aircrafts), for new types of urban and industrial distribution power networks and to bridge and support existing AC systems. Advanced power electronic components, power converters and system protection are enabling DC grids on multiple voltages levels. Especially medium voltage DC grids are expected to play a key role in managing the higher power flows in our future distribution grids. Roadmap for DC and different steps and research at the TUD is presented with focus on DC grids and DC microgrids. Problem of Power Flow control in DC grids is addressed first an Power flow controller introduced. A zonal protection framework where the low voltage dc grid is partitioned according to short-circuit potential and provided degree of protection, and several known protection schemes that ensure selectivity, sensitivity and security will be discussed. Finally the design criteria of solid state circuit braker for LVDC grid protection is discussed.
