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 […]

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 […]
