Power Systems Modeling Engineer Sr

As a Power Systems Planning Modeling Engineer you will develop transmission system models used in both real time operations and in transmission planning. These models support the delivery of power to everyone in the ERCOT grid and the planning of billions of dollars of transmission system projects. You will be joining a team that performs industry leading power systems modeling and model management. In power systems modeling you will develop steady state, short-circuit, and geomagnetic disturbance planning models in conjunction with ERCOT transmission service providers. You will also help improve system modeling processes and develop software tools to manage and validate model data. Good communication skills will be needed as this role will involve working with numerous internal and external stakeholders to build transmission system models.

ADDITIONAL JOB DUTIES

Planning Model Development

• Develops steady state and geomagnetic disturbance models with the Steady State Working Group (SSWG) using Model On Demand (MOD) and PSS/E

• 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)
