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 […]

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 […]

Updated and Validated Power Flow Model of the Main Continental European Transmission Network

View Paper Authors Abstract The advent of liberalisation of the electricity market in Europe has seen the growth of cross-border trading of energy. Zhou & Bialek published in 2005 a paper outlining an approximate model which simulated the real network and could be used to analyse the effects of cross-border trades in a test environment. This paper presents an […]

Video Capture

PowerWorld Simulator does not include a built-in tool for video capture or movie making. Commercial and freeware tools are available from other sources to capture video from PowerWorld Simulator, Retriever, and any other desktop applications. Current offerings may be found here, or by simply searching online for video capture software.
