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 […]

GIC Modeling Data Requirements
Some general guides for substation and transformer inputs needed for GMD analysis may be found in the following links, with some specifics as they pertain to PowerWorld Simulator: A spreadsheet template (updated 2/14/2017) which describes the input data for substations and transformers needed to perform GIC analysis. (These are inputs that do not occur in FERC […]

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 […]

Initial wiggles in a very small transient stability case
A common question when a user first starts playing with very small transient stability test cases is “Why do I see wiggles in my plots with no disturbance?” On large transient stability simulations there can be many different reasons for this, but for a 9 bus, 1 generator case you would rightly not expect to […]

Remote License Troubleshooting
If you are trying to start Simulator or Retriever using a remote license but the hardware key is not detected, you may need to manually point to the hardware key’s location on the network. To configure where your machine goes to look for remote license keys, make sure to run the full Simulator or Retriever installation […]

Calculating the Net Reactive Capability Curve of a Renewable Energy Plant and Subsystem
When studying a system of small renewable generators that are all hooked up to the power system through one interconnection point, some PowerWorld users have been interested in calculating the net reactive capability curve seen at the utility interconnection point. As an example consider the power system below which has the following characteristics. Three solar […]
