Voor grotere of nieuwe aansluitingen voor terug leveren
Netbeheerder Ruimte en tijd •
De discussie met Alliander loop al meer dan 10 jaar over de locatie, om de problemen in de Haarlemmermeer aan te pakken. Hier zijn twee stations nodig.
•
Er wordt nog niet gesproken betreft de laagspanningsinfrastructuur. Het gaat alleen maar om twee extra aansluitvermogen ophoogspanningsnet van Tennet.

Energie transitie “Een toekomst bestendige betrouwbaar netwerk” Dit is de slogan van Rutten IV Dit roept veel vragen op: • Wat is toekomst bestendig • Wat is betrouwbaar • Woningbouw en energie transitie zijn volledig afhankelijk van de elektrische infrastructuur • Welke visie wordt gehanteerd

Net problemen Aalsmeer Actueel per 24-jan-2022
Wachten Alliander waarschuwt voor problemen op die volle plekken. Bedrijven en consumenten moeten langer wachten op een nieuwe aansluiting, of op een verzwaring van de bestaande aansluiting voor bijvoorbeeld een warmtepomp of laadpaal. Consumenten met zonnepanelen kunnen niet meer op elk moment van de dag stroom terug leveren aan het net. Dat komt dit jaar al 33% vaker voor dan vorig jaar.
Geen ruimte voor duurzame opwek

• Hoeveel zwaarder is voldoende?
Oplossing • Hebben we genoeg mensen? • Hebben we de ruimte? net verzwaring? • Nemen we de kosten van niet
afgeschreven kabels voor lief? • Willen wij voor de toevoer meer hoogspanningsmasten? • De netbeheerder mag niet te veel verzwaren en anticiperen! • Infra structuur in de gebouwde omgeving gaat plat! 2021 DC Systems. All Rights Reserved. |

Grow of the system is needed
• Heat and Transport become part of the electrical system • More people result in more energy • The system must grow minimal with 200% based on the current consumption • But in 2050 how much is needed?

Laad methode voorbeeld •
Thuis laden gecombineerd met zonnepanelen, het goedkoopst voor de gebruiker.
•
Op openbare laadpalen, fors duurder voor de gebruiker.
•
Snel laad stations. Moet op de route liggen wachttijd en zeer duur

Reken voorbeeld auto verbruikt 200Wh/km accu capaciteit 90kWh •
Thuis 0,045 euro / km 18,8 euro/tank
•
Op straat 0,09 euro/km 40,5 euro/tank
•
Snel laden 0,13 euro/km 58,5 euro/tank
•
Tanken op de zaak zal het verschil nog groter maken
•
Woningen met veel PV maken het nog gunstiger voor de bezitter.
Effect voor mensen Thuis laden Openbaar laden
Twee deling in de maatschappij met sociale gevolgen • Niet iedereen kan op zijn eigen erf laden • Openbare laadpalen kunnen niet voldoende geplaats worden. • Wie niet kan thuisladen met zijn of haar elektrische auto is onder meer afhankelijk van het openbare laadnetwerk hogere kosten. • Als je geen plek kun vinden dan wordt je gedrongen bij snel laadstations te gaan, nog hogere kosten • Hoe lager het inkomen hoe duurder het rijden met de huidige maatregelen. 2021 DC Systems.

De Visie Wat is ons masterplan (in 2004 al begonnen aan de ontwikkeling van dit doel)
• Keep existing AC infrastructure unchanged (don’t remove old investments if the are working) • New regulations for local DC grid existing regulations for the AC grid (enables local match makers) • Improve availability for the system • Bidirectional system from ground up • Reduce the distribution investments © 2021 DC Systems. All Rights Reserved. | Page 21
Wat willen we? De grootste uitdaging die we hebben om te komen tot een oplossing is: •
Ruimte in de regelgeving is er nauwelijks om het anders optelossen
•
Komen tot een realisatie in een wijk gezamenlijk met de overheid en netbeheerder en markt

The Current OS protocol for active DC microgrids focuses on congestion management, safety, resilience, and cybersecurity and does not require central real-time control. This Operating System is regarded by Schneider and Eaton as the proper basis for a global rollout of decentralized DC grids and can play a major role in the energy transition. Schneider and Eaton jointly decided to make this proven Operating System available to any product manufacturer around the globe, to secure compatibility of its product(s) with any DC microgrid running on the Current OS protocol. The open and independent Foundation was set up to make the necessary Intellectual Property available to any Adopter wishing to participate.

It is not about system efficiency but an efficient system
Requirements of electrical systems •
The need for more resilient system that can resist environmental issues for example hurricanes or earthquakes. (DC Microgrids)
•
Moving from OPEX driven energy production to CAPEX driven production. (DC Dynamic capacity)
•
Moving from reactive balancing the system to opportune driven balancing (DC Droop control)
•
Increase power in final circuits (DC solid-state protection)
•
More bidirectional loads and sources in building (DC current sharing)
•
Hydrogen in the system for application where electrical solutions don't make sense like high temperature processes, large mobile systems like trucks or airplanes etc. (DC to molecules)

DC is the
Last Chance for a compatible system DC makes it happen

Actions needed from the EU Actions from the regulators is required •
New regulation rules are needed for DC microgrids o where power capacity can be dynamic. o Capacity connection o AC and DC connection in buildings AC is connected to the existing system and the DC is connected to the local DC microgrid during the transition phase.
•
New stakeholders need to be introduced o DSO (distribution System Operator) o MGSO (Micro Grid System Operator)
•
Because the current situation is too comfortable for the existing suppliers. This will not bring speed to the problem but stimulates classical solutions, some force is needed.
•
Regulation free zones are a big need for learning and development
•
Regulators must be part of projects in a green deal structure

USB-C is the most used and global standard socket
DC Public Lighting more than 300km installed
New standard now up to 240W (48V@5A) Next step for LVDC buildings. In the past we have developed a USB-C 100W socket power directly from 350V DC. Demonstrated in the ABN-AMRO Circl building. We see a large use-case for DC Office buildings where power planning is a huge issue. This is why we have developed local 48V areas supplied from 350V of 700V DC System based on Current/OS including protection and autonomous congestions control. The 48V Desk socket is able to supply 3x USB-C devices of 100W each. One socket provides also highspeed ethernet which can be used for power and data to a laptop for example.
