Job Description

Modeling Engineer

Both periodic and emergency onsite work may be required, but flex/hybrid work plans are broadly supported. The initial training period for up to six months will require an onsite presence 2-3 days per week. Once initial training is completed, longer term flexible/hybrid work schedules can be negotiated.

GENERAL POSITION SUMMARY:

The Modeling Engineer Contractor position aides those supporting the real-time EMS system model development and maintenance using the Siemens Information Model Management (IMM) tool. The Engineer will participate in the coordination of the EMS database update and single line display building process to insure a coherent system model providing accurate modeling of real-time power system conditions using the Common Information Model (CIM). Other responsibilities include system database expansion for support of new and existing members, interfacing with Operations, Planning, and Markets staff to incorporate requested application, display, and model changes, and tuning of the State Estimator during the model update process. The engineer will also test and perform maintenance to the EMS Transmission Network Applications (TNA) suite of tools.

Sometimes the contractor may be asked to create training materials for use by internal staff on processes and procedures related to the model update process and the support of TNA.

The candidate should have a proven ability to learn rapidly through a combination of mentorship and self-guided-discovery, and the willingness to work in a critical real-time environment. Modeling timelines are very rigid and getting the work done can require additional effort as deadlines approach, however we do our best to minimize the impact. Both periodic and emergency onsite work may be required, but flex/hybrid work plans are broadly supported. The initial training period for up to six months will require an onsite presence 2-3 days per week. Once initial training is completed, longer term flexible/hybrid work schedules can be negotiated.

ESSENTIAL DUTIES AND RESPONSIBILITIES:

• Define and Maintain Bulk Power Transmission and Generator models in the EMS
• Evaluate and Maintain model data accuracy in the EMS
• Review and process EMS model changes submitted by Transmission Owners (TO). Includes understanding power system schematics and basic equipment parameters as well as frequent communication with the TO
• Create and update accurate single line diagrams using a Siemens Graphical Editor
• Support the specification, testing, and development of the EMS system to ensure that it meets changing functional requirements
• Supporting the process used to transfer model update and parameter information from IMM to TNA and assisting in addressing issues experienced during the transfer
• Create and run scripts for comparison of transmission model versions in TNA
• Creation and maintenance of departmental process and procedure documentation in support of the model build process and support of IMM.
• Creation and maintenance of departmental process and procedure documentation to ensure compliance with Operating Agreement, manuals, and all applicable NERC and FERC requirements.
• Other duties as assigned

Required:

• Bachelor’s Degree with emphasis in Electrical Engineering (BSEE) or equivalent work experience
• Demonstrated knowledge and experience with real-time Energy Management System databases.
• Demonstrated knowledge and experience with real-time Energy Management System display generation software and electric power system display characteristics
• Demonstrated knowledge and experience with real-time Energy Management System transmission network analysis functions including State Estimation, Security Analysis, and reactive transfer limit (P-V curve) analysis
• EMS and power system operations experience including specific responsibility for EMS network modeling and/or EMS Network Applications.
• Experience with the specification, design, testing, implementation, modification and support of modeling tools and/or network applications.
• Excellent oral and written communication skills to facilitate customer support.
• Strong attention to detail
• High analytical and problem solving ability

Preferred:

• Master’s Degree with emphasis in Electrical Engineering (MSEE) or equivalent work experience
• Demonstrated working knowledge of any of the following: SQL/ORACLE, UNIX, VBA, PYTHON
• Knowledge of power system components and their database models
• Experience with Siemens Spectrum Energy Management Systems
• Demonstrated working knowledge of Power System Common Information Model (CIM, IEC 61970-301 & 61968-11)
