## ABB Enhances Power System Simulation Models for Grid Compliance

ABB has made significant improvements to its power simulation models for UNITROL 1000 Automatic Voltage Regulators. These advancements enhance simulation accuracy and usability to optimize system performance and ensure grid compliance.

UNITROL 1000 AVRs manage the voltage output of synchronous generators, providing a rapid and precise response to load changes, thereby maintaining voltage levels within the required range. These devices offer critical intervention against grid instability and electrical faults, protecting both the generator and the grid.

### ABB UNITROL 1000 Features

• Renewed component certification in accordance with German Grid Codes VDE-AR-N 4110 and VDE-AR-N 4120
• Guaranteed full compliance with grid connection regulations
• High-accuracy simulation models as digital twins
• User-defined models in DIgSILENT PowerFactory, PSSE, PSCAD, RSCAD simulation platforms

### Streamlining Grid Code Compliance

VDE-AR-N 4110 and 4120 certifications ensure that power generation units comply with the regulations required for grid connection. These standards are aligned with European Union Grid Codes, supporting national and EU-wide grid integration.

### Enhancing Power Grid Stability and Resilience

The need for verified simulation models is increasing in regions with high renewable energy penetration. Inaccurate models can lead to problems in planning and operations, and disrupt grid stability. The ABB UNITROL 1000 offers dynamic and precise voltage control, enabling reliable and efficient energy production.

"The updated models provide reliable digital representations that allow plant owners, transmission system operators, certification experts, and consultants to predict system behavior in various scenarios," explains Filipa Augusto Marques.
