Zappy - A Load Flow Modeling Tool For Power System Design With Gradient Based Optimization(LEW-20150-1)

Zappy is a software library build on top of the OpenMDAO framework written in the Python Programming language. It provides a modular software code enabling a user to perform standard power system studies, while also providing analytic derivative (sensitivity) calculations to the end user. These analytic derivatives make Zappy efficient when used by (or incorporated within) external software programs performing broader multidisciplinary optimization of electrical power systems.
