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 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 […]
