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 […]

Simple Weather Example
This example introduces the basic functionality of PowerWorld Simulator’s weather integration capability and how other features, such as contouring and geographic data views (GDV), can enhance visualization and interpretation of how the weather can impact wind and solar generation. The files may be downloaded here. To apply the weather data and visualize results: Open the […]

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 […]

PJM Base Case Setup Process
Motivation: PJM Network Model power flow cases typically have a large generation/load imbalance that result in large positive or negative generation at the island slack bus and distorted flows on nearby lines and transformers. The island slack bus is often located within PJM. A recent example has -6.6 GW at Peach Bottom (PEACHBOT 22.00 kV). […]

N-1-1 Contingency Scenario ATC Analysis
The ATC analysis in Simulator can include a set of contingencies defined in the contingency analysis tool during the ATC calculation. The key is getting that list of contingencies defined for the N-1-1 contingencies. Each contingency will have 2 actions defined, which Simulator will evaluate for outages when calculating the sensitivities used for the ATC […]

Applying Multiple Faults Simultaneously in Transient Stability
A common question that PowerWorld support staff receives is as follows. Question: Can I apply multiple faults in a transient stability simulation simultaneously? Answer: Yes, absolutely! We agree that normally this would not happen in real life situations, however there are studies that power engineers do that may require this. Our customers in North American […]

NERC Book of Flowgates
A spreadsheet template for importing interfaces from the NERC Book of Flowgates (2018 edition) may be downloaded here. To use the spreadsheet: Place the original data from the NERC Book of Flowgates in the gray shaded region (columns A through AE, beginning with the column headers in row 2.) Add additional rows as needed. Copy […]

GIC Time Varying Electric Field Example
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. Sample (B3D binary format) based on June 22, 2015 event [1], over footprint of the U.S. State of […]

New Feature: Data Check
A new feature was added to PowerWorld Simulator in the April 9, 2018 patch of Simulator 20 called “Data Checks”. Data checks grew out of work that PowerWorld customers Jonathan Young (Columbia Grid) and John Gross (Avista Utilities) performed building on PowerWorld Simulator’s features of Advanced Filters, Calculated Fields, Dynamic Formatting, Expression and String Expressions.
