SMIGHT GmbH has successfully tested and implemented its 14a load manager under realistic conditions. This enables the company to map the entire process chain with the SMIGHT IQ Copilot: from the recorded and reported overload to the triggering of a dimming command via BDEW-WebAPI to the relevant controllable consumption devices (SteuVE). The SMIGHT IQ Copilot also enables documentation in accordance with BNetzA and VDE FNN specifications.
The SMIGHT IQ Copilot offers distribution grid operators a secure solution for implementing the legal requirements in accordance with §14a EnWG. In view of the growing number of electric cars, heat pumps and storage systems, grid operators must be able to reliably detect bottlenecks and temporarily dim connected controllable load devices. The load manager supplements the SMIGHT IQ Cockpit for low voltage used by over 120 distribution grid operators with two automatic monitoring and control functions for critical grid areas. To test these, SMIGHT successfully tested and implemented the entire process chain in the EnQS GmbH test laboratory under realistic conditions: from triggering an overload to controlling a wallbox
Load management without a calculable grid model
The SMIGHT Copilot does not require a calculable grid model. Grid bottlenecks are precisely detected by SMIGHT sensor technology with a precise output and minute accuracy. In the event of a critical load, for example close to the fuse value, a dimming command is triggered in the system. If there is no longer an overload, the command is canceled again.
The generated dimming commands are transmitted to the relevant control units via the BDEW Web API. These can be assigned to the previously created local network stations and cable distribution cabinets in just a few steps in a map view. The process is then documented in accordance with BNetzA and VDE FNN specifications. The solution thus fulfills current regulatory and ISMS requirements and can be quickly adapted to future requirements.
If real-time measurement data is not yet available for a grid area, preventive time windows for dimming can be specified manually for the areas at risk. This ensures stability for all grid areas immediately.
“First and foremost, digitalization must ensure that the grid is under control with foresight,” explains Oliver Deuschle, Managing Director of SMIGHT GmbH. “However, if control is unavoidable, it must be seamless. The combination of easy-to-install measurement technology, web-based visualization and automated control makes our overall solution ready for immediate use without additional IT effort and contributes directly to grid stability.”
A webinar on our implementation of measurement data-based load management in accordance with §14a EnWG will take place on 7.11.2024 at 11 a.m. Registration via: https://smight.com/webinar-messdatenbasiertes-lastmanagement/
