How to specify different Voltage Deviation Limits for different buses in Contingency Analysis
PowerWorld Simulator allows you to monitor for violations based on the change in a value relative to the reference state (base case). This was already covered in the knowledge base article at WECC Post Contingency Voltage Drop Criteria Monitoring. This works well if you have the same percentage drop violation for all buses in your system. […]

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 […]

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 […]

Case Study in Using Auxiliary File Scripting with Advanced Filters, Custom Floats, and Expressions
This is a case study that demonstrates how to automate the process of replicating the net reactive capability curve from a set of renewable generators behind a small distribution system which is connected to a single utility bus. This serves as a wonderful example for demonstrating several topics. Use of auxiliary files to automate processes […]

How to specify when Transient Limit Monitoring starts monitoring for violations
Transient Limit Monitoring Many power systems require particular voltage or frequency performance during transient stability simulation. For example, in the Western grid in the United States and Canada, the organization WECC specifies particular performance for various “Category B” or “Category C” contingency events (see http://www.wecc.biz/library/Library/Planning%20Committee%20Handbook/WECC-NERC%20Planning%20Standards.pdf). PowerWorld Simulator’s transient limit monitors allow you to monitor for violations […]

What formats can Simulator read?
Simulator can read text file formats such as PTI PSS/E (*.raw) and GE PSLF (*.epc). These formats are commonly used by ISOs, RTOs, and regulators to publish power flow models for members and other interested parties. Simulator is read and write compatible with raw file versions 23 through 32 and epc versions 17 and earlier. […]

What is the difference between the *.PWB and *.PWD files used by Simulator and what are PowerWorld Project Files?
PWB and PWD stand for PowerWorld Binary and PowerWorld Display. The PWB files contain the actual power system data for the case. Traditionally, case files can contain large amounts of data. We store this data in a binary file to reduce the size of the file on your hard drive. Furthermore, data stored in a […]
