The meeting was opened by ir Kees van de Water, followed by the introduction by Richard van Heyningen Chairman KIVI Department of Electrical Engineering. This to that the department focuses on making the energy supply / electricity supply more sustainable within the framework of the energy transition, as this can be read in the " Energy Plan" with the substantiation in the report " The future Dutch full carbon-free energy system" and the symposia "EnergieNL2050 2016-2017"

The activities of the KIVI Department of Electrical Engineering further focus on:

1. Electrical energy engineering using sustainable electrical energy;

2. Smart Grids and Smart buildings / - Homes and Embedded Systems.

This was followed by Edward Coster of STEDIN Netbeheerder (Zuid-Holland) giving us insight into the effects and direct consequences of the energy transition on existing electricity grids, For this purpose, the structure and principles of the high-voltage , medium-voltage and low-voltage grids were explained first. For each sub-grid, the various influences resulting from the energy transition were depicted and then projected onto the existing grid infrastructure. Using various approaches and methodologies, it became clear that grid renewal and grid reinforcement can go hand in hand, provided a clear integral policy is adopted on which neighbourhoods will or will not be made sustainable and to what extent. Only then can the costs be kept manageable. Which we all ultimately pay for.

Mr Ab van de Molen, Strategist for grid development at STEDIN, then went into more detail on the theme "Off the gas" and showed that this is not very wise. The alternative to switching partly or completely to electricity, in addition to using green gas to provide heat in inner cities, for example, is a real alternative. In doing so, the gas can be stored and transported and distributed via the existing gas pipeline network with minimal modifications. Besides biogas, large-scale hydrogen production using an electroliser is expected. The renewable electrical energy generated with PV is then converted into hydrogen. Cooking is safely possible only with induction hobs, as the flame of the hydrogen is not visible.

Again, a central direction for concept formation is needed to indicate, which energy carriers for which areas, neighbourhoods will be made sustainable and when. The overriding advantage is that the residents of houses/citizens themselves can remain in charge of making their homes, plots of land more sustainable and not have this imposed on them.

This resulted at STEDIN in the "Trias Energetica Pragmatica 2018", in which

1. System selection / building infrastructure (carried)

2. Correct choice of energy carrier

3. Stimulating citizens /. relieving them

This presentation raised many questions and reactions from the audience (60), which were discussed in detail later over drinks.

Description

Sustainable energy transition with effects on quality of operation of energy systems / electricity grids and places additional demands on technical grid infrastructure

The KIVI energy plan states that CO2-free energy supply should be possible by 2050. The energy transition changes the use and load on the grid. This has major consequences for the grid infrastructure, necessitating additional technical requirements to maintain the quality of operations.

As KIVI section Elektrotechniek, we have focused our attention on the sustainable energy transition.
Four KIVI-EL symposia EnergyNL2050 were held at the University of Utrecht, where it became clear that a NL carbon-free energy supply in 2050 is possible, but that this energy transition infrastructure has to be technically feasible, as described in the White Paper: "The Future Dutch Carbon-free Energy System in 2050" (annex) and based on the reactions to the publication of the KIVI Energy Plan March 2018 in The Engineer.

To realise this intention in the electrotechnical infrastructure, it is expected that many stakeholders will have to take consensual decisions for major adjustments in the electricity and heat grids. In this context, the municipality of The Hague recently concluded an agreement with parties on the sustainability objective to realise this at municipal level. In this, STEDIN is a very important party.

Security of Supply & Sustainable Operations
As members of KIVI-Elektrotechniek, we are very interested to see how this process will proceed and have asked the grid operator STEDIN:
- how they stand on this?
- how are they collaborating with other parties? and
- how are they weighing up the technical possibilities?

The speakers from STEDIN address the challenge facing the grid manager to help facilitate the energy transition, guarantee security of supply and provide sustainable reliable operations:
- What is the impact of the energy transition on the development of electricity grids and a future-proof design?;
- What are the differences in approach with the approach of, say, forty years ago?;
- What are the challenges facing the grid operator in determining the long-term strategy of the electricity grids and how to deal with the uncertainty involved?

Prior to this meeting, the KIVI Electrical Engineering Department will hold the General Members' Meeting(ALV).
Please register separately for this!!! EL members will receive the agenda and documents separately by e-mail.

Speaker(s)

The first speaker is: Edward Coster, grid strategist MS and LS grids with the presentation:
"Stedin in transition, the challenges of the grid operator in the energy transition."

Edward Coster studied electrical engineering at TU Delft. He also received his PhD from TU Eindhoven on a study of the impact of combined heat and power (CHP) and distribution network security. His experience includes doing large grid studies in transmission grids (especially in the Rotterdam port area) and security studies of transmission and distribution grids. His current work focuses on determining the impact of the energy transition on Stedin's MS and LS grids.

The second speaker is: Albert van der Molen, asset management expert at Stedin with the presentation:
"The energy transition as a societal task."

Albert van der Molen studied at TU Eindhoven and University of California, Berkeley. His experience covers both electricity and gas, ranging from nuclear engineering to hydrogen. He is currently focusing at Stedin on making the existing built environment more sustainable, not excluding any solution direction.
