SMIGHT GmbH and advalju GmbH & Co. KG jointly demonstrate the successful implementation of §14a EnWG-compliant control in the low-voltage grid. Starting with the SMIGHT IQ Copilot load management software and advalju’s CLS management system, the entire active chain – from the grid operator to the controllable consumer – was tested under real conditions. Both companies presented this milestone live with an electric car at the Smart Energy Dialogue, an event organized by Theben.
In addition to the well-known IoT solution for measurement data acquisition and grid monitoring, SMIGHT also offers a solution for preventive and grid-friendly control: The SMIGHT IQ Copilot enables grid operators to intelligently control consumers at low-voltage level – tailored to the requirements of §14a EnWG.
Technical implementation: tried and tested
SMIGHT and advalju were able to demonstrate the complete chain of action for the implementation of §14a EnWG as part of the Smart Energy Dialogue, an event organized by Theben Smart Energy. The control command is transmitted from the SMIGHT IQ Copilot via the CLS management to the Theben Smart Meter Gateway CONEXA with an attached value-added module as a certified control unit. From there, the control command is transferred via EEBUS to a home energy management system, which dims the wallbox in the property continuously. Communication between the backend systems is encrypted using the BDEW Web API. The control process is then documented via the SMIGHT IQ Copilot in accordance with the specifications of the German Federal Network Agency (BNetzA) and VDE FNN. This means that the solution meets current regulatory and ISMS requirements and can be quickly adapted to future requirements if necessary.
System integration
Thanks to the use of standard interfaces (BDEW API), the integration and interaction of the systems was quick and straightforward. Steffen Hornung, Managing Director of advalju, explains: “The respective technical experts connected the systems within a few hours. Internal end-to-end tests then took place, including the connected electric car. This meant that the showcase, which is actually a live demonstrator, was ready for use without any major effort.”
Control in the low-voltage grid – flexible, secure and interoperable
Even before the live demonstration with advalju, SMIGHT was able to prove its practical suitability at E-world: There, the control process was demonstrated with another market competitor.
The SMIGHT solution is interoperable: regardless of the modern metering device used: “We have already successfully addressed a large number of MSB APIs and are currently in intensive testing of the entire supply chain,” explains Oliver Deuschle, Managing Director of SMIGHT.
Five SMIGHT customers are currently starting so-called 14a pilot projects, including Stadtwerke Frankenthal GmbH and Stadtwerke Fellbach GmbH. The aim is to complete the technical integration and test the control chain in live operation. “We are therefore offering all our customers – and those who would like to become customers – the 14a projects to make it easier for them to get started in the 14a world and to gain valuable experience together,” Deuschle continues.
