“…The HTB is a power electronics-based testbed, which utilizes the fast, accurate, and flexible closed-loop control of power electronics converters to mimic the static and dynamic behaviors of electrical power components, and it can overcome many issues with digital emulators and conventional hardwarebased grid emulators [65,66]. It mainly aims at testing the transient conditions of the system and the performances of the power electronics converters and controllers.…”

This paper discusses the design, development, and testing of a flexible combined heat and power (F-CHP) system. It includes two parts: the power conditioning system (PCS) converter, which connects the system to the grid and is the key component to provide grid support services, and the F-CHP central controller, which accommodates the control of local sources, local loads, and the PCS converter. The functions and structures of the central controller are discussed. The central controller's system-level performances are verified with hardware-in-the-loop (HIL) tests, and the mode transition and grid transient performances are validated with power electronic converter-based hardware testbed (HTB) tests. The PCS converter is designed with 10 kV SiC MOSFETs. The grid requirements are considered in the 13.8 kV/1 MW PCS converter design, and the impact of different requirements on the converter design is identified. Also, converter scalability is studied with the paralleling operation. Two 13.8 kV/100 kW converter prototypes are developed to verify the converter design and scalability. The second prototype is an improved design of the first one; the volume is reduced by 49% and the efficiency at the rated output power is increased from 96.4% to 98.4%. The test results of the converter performances, grid support functions, and parallel operation are also discussed.INDEX TERMS 10 kV SiC MOSFET, Flexible Combined Heat and Power (F-CHP) System, grid support, grid requirements, medium voltage converter, power conditioning system (PCS).
