• Develops short circuit models with the System Protection Working Group (SPWG) using ASPEN One-liner
• Coordinates the model and contingency building processes for SSWG and SPWG, ensuring transmission service providers (TSPs) submit data, validates data submissions, resolves modeling issues, performs generation modeling and dispatching, and produces data products for the planning models
• Works with the SPWG and SSWG on data exchange methods and interfaces
• Develops new and updated modeling methodologies
• Develops methods to validate transmission models and modeling data
• Generation 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 generation sites and distributed generation resources in the ERCOT planning models using PSS/E and ASPEN
• Maintains and develops generation 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
• Manage projects to upgrade the MOD applications to implement desired new functionality, reviews system patches, and helps administers servers
• Other Responsibilities
• Provides training and mentoring of members of the Engineering Development Program (EDP)
