Microgrid Controls Engineer: EMS, Real-Time & Protection

Delta Electronics (Americas) Ltd.; Morrisville (NC); On-site; USD 120,000 - 170,000; Full time

Job summary

Delta Electronics (Americas) Ltd. is seeking an experienced engineer to lead end‑to‑end EMS optimization, real-time control, and protection coordination for utility‑grade and hyperscale microgrids.

This role focuses on translating business and reliability goals into deployable control functions with safe, stable operation across grid-connected and islanded modes. The successful candidate will design optimization algorithms, coordinate across PCS, BESS, generators, and DER assets, and ensure

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Power Systems, Controls, or related field.
• 3–8+ years of experience in microgrid controls, EMS/supervisory control, real-time control, and/or protection-coordinated control design.
• Strong understanding of inverter-based resources, microgrid operating modes, and dynamic control concepts (frequency/voltage/power coordination).
• Experience defining command arbitration/authority models across EMS, real-time control, SCADA/HMI, unit controllers, and protection relays.

Responsibilities

• Design EMS optimization algorithms (economic dispatch, reserve management, resilience planning, emissions objectives, and degradation-aware operation)
• Implement day-ahead, intraday, and rolling-horizon optimization with robust fallback strategies and operator override handling
• Translate EMS schedules and setpoints into supervisory control intents that respect real-time stability, ramp limits, and protection constraints
• Define EMS constraints and feasibility checks (asset limits, network limits, N-1/contingency policies) and document assumptions
• Analyze operational performance, tune objectives/constraints, and drive continuous improvement of optimization outcomes
• Design protection-aware control limits, interlocks, and adaptive constraints aligned with relay behavior and unit controller protection functions
• Coordinate inverter-based and traditional protection strategies for grid-connected and islanded operation
