Innovative grid status assessment with PQ Plus and GridCal.
Compliant with Section 14a of the German Energy Industry Act (EnWG) and the VDE FNN recommendation. Reduce fee-based TAF 10 data transmission by up to 75% with GridCal.
PQ Plus and GridCal enable grid operators to implement the requirements of Section 14a of the German Energy Industry Act (EnWG) and Section 9 of the Renewable Energy Sources Act (EEG) in a cost-effective, scalable, and legally compliant manner – with a focus on real-time transparency, reduced query activity, and sovereign grid control.
Measurement in the grid area:
Reduction in the need for TAF 10 calls due to the deployment of measurement technology in local network stations.
Grid status assessment:
The goal is to ensure a continuous assessment of the grid status. According to BNetzA specification BK-622-300, grid status assessment must be carried out based on minute-by-minute measurements.
Definition of grid bottlenecks:
Thermal overload of equipment and a voltage range violation according to DIN EN 50160
- Undervoltage or overvoltage of the average effective voltage of 230 V (±10%)
- Power overload of a grid connection when drawing power from or feeding power into higher grid levels
- Exceeding the continuous current carrying capacity of lines
Control measure according to Section 14a of the German Energy Industry Act (EnWG):
Preventive dimming:
Max. 2 hours per controllable consumer device per day:
► Transmission of control command
Grid-oriented dimming:
Real-time detection of a bottleneck ► Transmission of control command
HEMS:
Home Energy Management System:
An intelligent system that optimizes and controls energy consumption and generation in a household.
Stb-VE:
Controllable Consumer Device:
Electrical consumers with a grid connection capacity of more than 4.2 kW and intended to optimize the low-voltage grid.
iMSys:
Intelligent Metering Systems:
Modern metering devices with a communication unit (smart meter gateway) that enable secure data transmission.
TAF 10:
Tariff Application Case 10 (TAF 10):
A defined use case within the smart meter framework that enables grid-status-related load profiles to be regularly retrieved from the IMSys.
CLS Management:
Controllable Local Systems Management: A system for the secure control and
monitoring of intelligent consumer devices (smart meters).
