Simulation Engineer, EMS

The Simulation Engineer reports to the EMS Controls Engineering Manager and will be responsible for designing, developing, and configuring PSCAD models for supporting Power Plant Controller (PPC) deployments within the Energy Management System for Energy Storage Systems (ESS). This position will contribute by having their solid foundation in power system modeling and digital control system automation. The position will be the Subject Matter Expert (SME) in PSCAD and benchmark results against control HIL (cHIL) simulations with Typhoon HIL hardware. This position also involves troubleshooting control logic interactions with various OEM inverter controllers.

Essential duties and responsibilities are included, but are not limited to the following:

· Create PPC models in PSCAD and test responses to closely model the responses from field measurements. This includes all PID loops and real and reactive stacked power functions.

· Lead 3rd party PSCAD study efforts by creating PPC control loop specification drawings and provide other OEM technical information like inverter models. Receive models from 3rd party and review results and implement improvements.

· Improve the PPC and Inverter models to more closely align responses with reality. design and other technical information from suppliers and contractors, including PSCAD studies and PPC control loop specification documents for transient studies.

· Develop and maintain design, solution, and component specifications that are part of the PSCAD PPC model to support controls logic testing and validation, either for new unit code implementations or production support issues.

· Collaborate with the HIL Engineer in the future development of Typhoon HIL simulation project files and integrate HIL Connect modules with IO modules.

· Assist in SEL735, SEL700G, and SEL3555 hardware devices that are connected to the HIL testbed. Also included will be to deploy TCP/Modbus or C37.112 PMU servers or clients that interface with production power plant controllers by implementation of emulators.

· Assist in battery power plant (BPP) Commissioning operations efforts including power dispatch, troubleshooting discrete HW issues, and coordinating with Commissioning Leads.
