NETfficient Demonstration - Use Cases Updates

The demonstration in the real environment on the Island of Borkum is driven by five Use Cases covering low voltage and medium voltage scenarios and a wide range of applications and functionalities.

More infos by "click" on blue highlighted sections (link will open in new tab).
Updates on the following UC are currently available:

  • Use Case 1 - Peak shaving and ancillary services in the market
  • Use Case 2 - Homes
  • Use Case 3 - Buildings
  • Use Case 4 - Public Lighting
  • Use Case 5 - Aquarium water temperature regulation

Use Case 1 – Peak Shaving and Ancillary Services in the Market

Installations for NETfficient energy storage technology HESS – Hybrid Energy Storage Solution (i. e. Use Cases 1-3) at heating centre („Heizzentrale“) at premises of partner Wirtschaftsbetriebe Borkum have started.
Figures 1-2 (left, center) give an insight into installation process showing ground works and laying of cables for HESS at the outer ground of premises of Wirtschaftsbetriebe Borkum.
Figure 3 (right) shows the control center at Wirtschaftbetriebe Borkum, the core of NETfficient's energy monitoring, communication and grid control.

Use Case 2 – Homes

During installations for Use Case Homes, several homes were equipped with solar PV modules, that are most essential parts of i.e. Use Cases "Homes" and "Buildings".

The following figures show the installations of solar PV modules on volunteers homes for Use Case 2:

Use Case 3 – Buildings

One of the demonstration sites of the Use Case - Buildings is Tourist Information (TI) Borkum at Borkum city centre, which is part of the services maintained by NETfficient partner Wirtschaftsbetriebe Borkum. Installations have started at the beginning of 2017.

During the installation Tourist Information’s buildings were equipped with sets of smart energy devices and components that will allow Smart Energy Control and Management and support Smart Energy Services. For instance the roof top of one of the facility buildings was euipped with solar panels (PV system).

Figure 17 shows the Tourist Information Borkum (front view) as demonstration site of the Use Case - Buildings before the installations. By figures 1 - 2 you can follow the setup of solar PV modules on the rooftop of one of the facility buildings. (Please "click" on the figures to enlarge images.)

Use Case 4 - Public Lighting

In Use Case - Public Lighting, certain streets on the Island of Borkum will be illuminated using PV, battery system and light bulbs (figues 18 - 19: LED with 24 o. 27 W).

The selected technology for bulbs is LED (manufactured by CONPOWER Betrieb GmbH & Co. KG). For this use case, 50 light points will be used, and they will be separated from the rest of the light system, controlled by Wirtschaftsbetriebe Borkum. This new system will be a stand-alone system controlled by the DMS.

Its main ambition is to consume the energy supplied by the sun during daytime for lighting at night and to improve the street lighting system maintenance service.

Technically for Use Case - Public Lighting, the street lighting is connected via a DSL router or a mobile communication modem to the Energy Management Platform (EMP). The EMP will offer energy and aggregated management platform’s functionalities to the public lighting DERs (e.g. DER monitoring, DER Aggregation functionalities, Asset Management, Measures curve Tools, Maintenance management) [figure 20].

Figure 21 shows the streets on Borkum chosen to be installed with new street lighting system.

Installations for Use Case - Public Lighting: In March sensors for weather station on the rooftop of projectpartner Wirtschaftsbetriebe Borkum I (Heizzentrale Hindenburgstr.) were installed and connected to the technical equipment for energy monitoring, data generation and facility maintenance at control center (showroom) at Wirtschaftsbetriebe Borkum.
The following figures (no. 2-7) show the installation process of sensors (craftsmen using a work lift for installations at house wall) and data generation and monitoring at control center at Wirtschaftsbetriebe Borkum (figures 8-9).

Use Case 5 - Aquarium Water Temperature Regulation

So far Use Case - Aquarium Water Temperature Regulation is completely designed, and installations at the demonstration site “Nordsee Aquarium Borkum” have started in 2017.
As shown in short 3D-Video Simulation (by Wirtschaftsbetriebe Borkum), solar PV modules were installed on the rooftop of Borkum Aquarium.
While figure 22 shows the view of Borkum Aquarium rooftop, before installations, figures 5, 9 and 10 show the installations process on Borkum Aquarium, and its rooftop with sucessfully intstalled solar PV modules.
