Easy SimAuto (ESA): An easy-to-use Python connector to PowerWorld Simulator Automation Server (SimAuto).

Project description

Easy SimAuto (ESA) is an easy-to-use Power System Analysis Automation Platform atop PowerWorld’s Simulator Automation Server (SimAuto). ESA wraps all PowerWorld SimAuto functions, supports Auxiliary scripts, provides helper functions to further simplify working with SimAuto and also turbocharges with native implementation of SOTA algorithms. Wherever possible, data is returned as Pandas DataFrames, making analysis a breeze. ESA is well tested and fully documented.


For quick-start directions, installation instructions, API reference, examples, and more, please check out ESA’s documentation.

If you have your own copy of the ESA repository, you can also view the documentation locally by navigating to the directory docs/html and opening index.html with your web browser.
