Release Notes 4.6

New: E-Interconnect Toolbox

The E-Interconnect Toolbox is the most powerful and essential tool for automating model quality tests and conformity assessments required for IBR (Inverter-Based Resource) grid interconnection studies. This game-changing solution is redefining how interconnection studies are done, accelerating workflows and reducing engineering time to perform all simulations required.

  • Fully automated execution of all IBR model validation tests, including numerical stability, flat start, time-step sensitivity, dynamic performance evaluation, and multi-instance testing without manual intervention.

Automates compliance testing with grid codes, covering Low-Voltage Ride-Through (LVRT), High-Voltage Ride-Through (HVRT), frequency ride-through, and voltage angle ride-through across all power and control modes. Intelligent pass/fail logic with automated report generation in Word format, complete with waveform plots ready for documentation and sharing. Make grid code compliance faster, easier, and more reliable than ever before!

New: Parametric Studio Toolbox

  • Unlock the full potential of parametric analysis with Parametric Studio, the most powerful no-code tool in EMTP®. Perform sensitivity, contingency, and uncertainty evaluations effortlessly, without writing a single line of code. Effortlessly create multiple parameter variations using statistical distributions or predefined value lists. Create variations in signal connections to modify power system topology.

Variations are stored in a dedicated, reusable database, ensuring design consistency and flexibility. High-performance parallel processing runs multiple simulations simultaneously, saving time and resources.

It Includes a brand-new graphical interface, built to visualize massive sets of signals, with embedded post-processing and data export capabilities.
