Modular AC/DC Grid Emulator for Research and Development

Background
The University of North Carolina at Charlotte is issuing this solicitation to procure an AC/DC Grid Emulator aimed at advancing research and development in grid-enhancing technologies.
The emulator is expected to be modular and scalable, accommodating various power levels and configurations for both source and load.
The goal is to support innovative solutions that enhance the efficiency and reliability of electrical grids.

Work Details
The contract requires the provision of a modular AC/DC Grid Emulator with the following specifications:
- Must support power regeneration capability and be fully bi-directional.
- AC and DC grid emulation capabilities are required, which can be achieved through dedicated modules for each mode.
- Operation should be facilitated by a user-configurable remote Human-Machine Interface (HMI).
- Specific performance requirements include:
- AC Output Modes: 4 Quadrant Grid Forming (voltage source) and 4 Quadrant Grid Following (current source/sink).
- Configurations: 3-phase AC, 1-phase AC.
- Minimum Power per Module: 50 kVA; Minimum Installed Power: 180 kVA; Minimum Power Scalability: 500 kVA.
- Frequency Range: 40-75 Hz; Voltage Range: 0-576 VAC L-L; Maximum Total Harmonic Distortion (THD): 1%.
- DC Output Modes: Bi-directional Constant Voltage Source and Bi-directional Constant Current Source/Sink with minimum power per module of 50 kW.
Delivery must be completed by June 15, 2025, to the Energy Production and Infrastructure Center (EPIC) at UNC Charlotte.

Period of Performance
The contract performance period extends until June 15, 2025, by which time all products must be delivered.

Place of Performance
The products will be delivered to the University of North Carolina at Charlotte's Energy Production and Infrastructure Center (EPIC), located on campus.
