Develops new and updated modeling methodologies

Develops methods to validate transmission models and modeling data

and Load Modeling

Reviews generator and transmission equipment data submitted by resource entities and works with resource entities to correct invalid model data

Models transmission sites and distributed resources in the ERCOT planning models using PSS/E and ASPEN

Maintains and develops modeling tools written in Python and C#

Models co-located Large Loads and reviews Large Load data in planning models

Modeling Application Support

Manages transmission system model software infrastructure and develops tools to assist in managing transmission models which includes database infrastructure, model data exchange interfaces, and data export formats

Develops and maintains modeling software tools in Java, C#, Python to validate transmission network and generator data submissions using electrical engineering principles by doing data comparison and validity checks, and to automate and perform system modeling

Develops rules to validate data submissions in operations and planning models using SQL
