Example of Geomagnetic Induced Current (GIC) Calculations
Appendix II of the Application Guide: Computing Geomagnetically-Induced Current in the Bulk-Power System published by the North American Electric Reliability Corporation shows calculations of GIC currents and related quantities for a hypothetical power system with 6 buses and 3 substations. This system is available here for use in PowerWorld Simulator. These may be examined in the free […]

Renewable Transient Stability Modeling for Wind and Solar plants
This article covers how to model a wind or solar plant using the second generation wind turbine models that have been developed through WECC’s Model Validation Working Group (MVWG). The details of these models are explained in detail in PDF documents on the WECC website at the following link: WECC MVWG Approved Model Specifications You […]

Registering SimAuto
SimAuto must be registered in the Windows Registry before it can be referenced from external programming platforms. This normally happens automatically when Simulator is installed, but may need to be performed again if there is a hardware change or if you are working with multiple versions of Simulator. (Only one version of SimAuto may be […]

Physical Security Assessment
On March 7, 2014, FERC issued an order directing NERC “to submit for approval one or more Reliability Standards that will require certain registered entities to take steps or demonstrate that they have taken steps to address physical security risks and vulnerabilities related to the reliable operation of the Bulk-Power System.” PowerWorld Simulator can easily […]

D-FACTS Quick-Start Tutorial
Distributed Flexible AC Transmission System (D-FACTS) devices or “smart wires” change the effective line impedance of the transmission line on which they are installed. The Knowledge Base Article is a quick-start tutorial that introduces D-FACTS devices and how to use them in PowerWorld Simulator. This is a short hands-on training session with slides and sample cases. […]

Comparing Contingency Results
The Knowledge Base Article will cover how to take several contingency analysis runs done on the same system topology under different conditions and then build an Microsoft Access database that uses a query to compare the results across different contingency runs. Creating a Test Example of Three Different Contingency Analysis Runs on the same case […]

WECC Post Contingency Voltage Drop Criteria Monitoring
Note, this knowledge base article provides a very simple feature for monitoring for voltage deviation monitoring, however if you need more flexibility than is shown below, there are two other knowledge base articles related to this one which provide much more flexibility than is shown below. Links to these knowledge base articles are as follows. How […]

Motor Load Starting using Transient Stability
Note: Download a small sample case at the following link which is used in this demonstrate: MotorStart Case Note: Starting in the July 10, 2013 patch of Simulator 17, a modification was made to automatically change the integration time step for the entire simulation when induction motors (loads) or induction machine (generators) drop below 0.1 per […]
