Abstract

This deliverable consolidates the final specifications for the Use Cases (UCs) to be demonstrated in Denmark. The deployment plan includes an initial assessment of the current infrastructure at both locations, i.e., Risø and Campus Bornholm. Risø is a research campus of the Technical University of Denmark (DTU) and located in Roskilde, while Campus Bornholm is an educational institute in the main town Rønne on the island of Bornholm. Based on the assessment of both locations, the present document presents a detailed description of hardware and software that will be implemented, and the associated construction works required for their deployment.

The Electric Vehicle (EV) charging infrastructure is identical at both locations and comprises six Alternating Current (AC) chargers (22 kW), respectively. Each of the six AC chargers has two outlets, providing the opportunity for twelve EVs to be connected at the same time. The charging infrastructure is integrated via a 43 kW grid connection, and operated through a load management system enabling the maintenance of aggregated consumption below a specified threshold. This offers various benefits, e.g., preventing component overloading or the provision of both local and external services, such as peak shaving, increasing self-sufficiency, and frequency control.

Each charger deployed in this project is equipped with a controller that enables the charger to make autonomous control decisions. This facilitates distributed control schemes where all chargers are provided with global quantities, such as the cluster reference power and the actual cluster consumption, based on which all chargers individually control their respective charging session to collectively meet the cluster requirements.

Users of the charging infrastructure will start their charging sessions through an app, which is developed as part of the EV4EU project. The app allows the user to provide key inputs, such as the anticipated parking time and the required energy, which enable the load management system to consider user preferences while controlling the overall cluster consumption. The data acquisition and logging further include high-resolution power measurements at each charger, and of the overall cluster consumption through a dedicated meter at the point of common coupling (PCC).

Moreover, the deliverable proposes 19 Key Performance Indicators (KPIs) for quantifying the performance and impact of the demonstration activities. The KPIs are organized in four main categories, addressing economic, technical, user related, and environmental impacts. Finally, the document summarizes the current status of the infrastructure deployment and gives an outlook for the upcoming tasks within the Danish demonstration. Specifically, Task 9.2 will finalize the already well-advanced deployment and commissioning of the charging infrastructure at both locations, followed by the start-up of operation.
