Real-Time Microgrid Firmware Engineer - Grid-Forming

Delta Electronics (Americas) Ltd.; Morrisville (NC); In loco; USD 140.000 - 180.000; Tempo pieno

Descrizione del lavoro

Delta Electronics Americas in Morrisville, NC seeks an experienced engineer to own the real-time control software for the Microgrid Controller. You will implement deterministic control loops, grid-forming/grid-following logic, and protection coordination for PCS, BESS, PV, and genset assets, validated on HIL platforms.

The role requires embedded C/C++ on RTOS/Linux, knowledge of IEC 61850, model-based design, and hands-on verification and documentation for certifications.

Competenze

• B.S./M.S. in Electrical Engineering, Power Electronics, Controls, or Computer Engineering (or equivalent experience).
• Strong grasp of power-electronics control — inverter current/voltage loops, PLL, grid-forming/grid-following.
• Hands-on real-time embedded software in C/C++ on RTOS or PREEMPT_RT Linux, with bounded WCET and deterministic scheduling.
• Practical experience with industry controllers / IEDs.
• Working knowledge of power-system protocols: IEC 61850 (GOOSE/MMS), Modbus, DNP3, and PTP.
• Experience with model-based design and HIL (MATLAB/Simulink, PLECS, Typhoon HIL / OPAL-RT / RTDS) and test automation in Python.
• Ability to read SLDs, I/O lists, protection settings, control narratives, and register maps; clear technical writing for specs, test plans, and release evidence.

Mansioni

• Develop the MGC real-time control application on a deterministic RTOS/RT-Linux target — droop/VSG, PLL, GFM/GFL reference generation, P/Q dispatch, and bumpless mode transitions within ≤ 1 ms loops
• Implement secondary control (P-f and Q‑V droop, virtual inertia, SOC‑aware allocation, ramp‑rate limiting, black‑start sequencing, resynchronization) at the 1-100 ms layer
• Build protection coordination logic (50/51, 27/59, 81/81R, anti‑islanding, interlock state machine, GOOSE fast trip/block) with hardware trip paths executing in ≤ 20 µs
• Design and tune power‑electronics control loops interfacing to PCS/BESS unit controllers; validate stability, ride‑through (LVRT/HVRT), and grid‑fault behavior
• Configure and program industry controllers
• Implement deterministic comms and middleware — IEC 61850 GOOSE/MMS/SV, Modbus TCP, DNP3, PTP (IEEE 1588), lock‑free IPC (DDS / shared‑memory SPSC queues), with no dynamic allocation on the RT path
• Verify all functions on HIL (Typhoon HIL, OPAL‑RT, RTDS, dSPACE) for grid‑tied, islanded, black‑start, failover, and fault‑injection scenarios.
• Support certification and release evidence — UL 1741 SB, IEEE 1547, IEC 61850 conformance, IEC 62443 / NERC CIP — with clear design and test documentation
