PowerWorld Simulator Integration with EPRI GICHarm
Beginning with version 24, PowerWorld Simulator’s GIC add-on is integrated with the Electric Power Research Institute’s (EPRI) GICHarm tool. The latter performs harmonic analysis on grid connected devices such as capacitor banks to determine if expected geomagnetic induced currents (GICs) could cause them to trip. This integration enables an iterative analysis, summarized by: Using an […]

May 2024 GMD Event (Gannon Storm)
Below are visualizations and power flow simulations of the North American geomagnetic disturbance of May 10-12, 2024 (Gannon Storm). The simulations utilize surface electric field models developed by NOAA Space Weather Prediction Center with Empirical Magnetotelluric Transfer Functions (EMTF), which incorporate the full 3D effects of Earth conductivity structures. Surface Electric Field only (CONUS) Eastern […]

Generic Excitation Limiter Implementation
Type C excitation system transient stability models, as per IEEE standard 421.5-2016, have the ability to allow limiters to be added at one of multiple points within the model. The excitation limiters models also allow their own parameters to be modified, in order for them to be compatible with the exciter model that is in […]

Time-Step Weather Example
This example shows how historic and forecast ERA5 weather files can be loaded into PowerWorld Simulator and be used to determine the Max MW capability of wind and solar generation. Features such as contouring and geographic data views (GDV) are also applied to enhance visualization and interpretation. The files may be downloaded here. Here is […]

Power Transfer Limit Exceeded by OPF
The Optimal Power Flow (OPF) solution involves iteration between a linear program (LP) to adjust controls (usually generation) and a non-linear power flow. If an AC OPF is performed over a very large Area (or Super Area), the LP may attempt to dispatch generators in a manner that exceeds voltage stability margins (PV) or maximum […]

EMP Waveforms Based on Published Research
The newest builds of PowerWorld Simulator with the GIC add-on no longer contain a function to calculate time-varying series voltage inputs for EMP E3A and E3B time and spatial functions based on Oak Ridge National Laboratory (ORNL) research [1] and International Electrotechnical Commission (IEC) standards. Going forward, non-uniform time and spatially varying electric fields will […]

Historic North American GMD Events
PowerWorld Simulator supports binary and text file formats for time and spatially-varying geomagnetic disturbance (GMD) surface electric field inputs. This format allows development of detailed solar storm scenarios based on historic events or 3D earth conductivity models. Surface electric field models developed by NOAA Space Weather Prediction Center with Empirical Magnetotelluric Transfer Functions (EMTF), which […]
