Introduction to Smart EV Charging through the Smart Solar Charging pilot

Welcome
My name Nico Brinkel, started about a month ago on Smart Solar Charging project, as a researcher on smart charging. Even though new to the topic, and not involved in Smart Solar Charging operation itself, I will introduce you to this project, and to the need of smart charging.

2. Smart charging Uncontrolled charging Smart charging Grid capacity
To introduce you to smart charging, first introduce the base situation: We expect a large growth in the number of EVs. Normally, they start charging at the moment everyone comes home from work. This is the moment with the highest household demand. Therefore, one problem we can expect is that the grid capacity is exceeded, causing that grid reinforcements are required. Also, we do not charge at the moments with the highest solar generation.
Therefore, it would be better to charge at different moments. EV much longer connected.

3. Smart charging Smart charging: shifting EV demand over time
Based on different objectives:
Minimizing charging costs
Avoiding grid congestion
Providing balancing reserves
Energy independence
Maximizing solar self-consumption …
So smart charging is shifting EV demand over time. This is a broad concept, but important to note that it is not necessarily to avoid grid congestion. Smart charging can also be caused to minize charging costs, with low electricity prices. This can even cause grid congestion, as EVs start charging at the moments with low electrictity prices. Other types of smart charging: help the tramsission system operator, maximize solar self-consumption. All different charging behavior, but shifting EV demand over time.

4. Smart charging Uncontrolled charging Smart charging with V2G
Can be expanded: A new concept is Vehicle-to-grid, in which EV injects electricity into the grid. So at peak, EV injects electricity to the household, so grid stress even lower.

5. First V2G charging pole opened by King
First V2G charging pole opened by King. And this is a nice bridge to the research project I am working on, because this V2G charging pole was opened in the Smart Solar Charging project.

6. Smart Solar charging project
