Controller and Power Hardware-In-Loop Methods for Accelerating Renewable Energy Integration

This paper describes the basic concepts behind controller hardware-in-the-loop (CHIL) and power hardware-in- the-loop (PHIL) experimental testing from a renewable energy system integration perspective. An entire power apparatus or sub-system such as a power electronics converter for a fuel cell system or a variable speed wind power generator system can be tested in a controlled laboratory environment such as the 5 MW rated hardware-in-the-Loop (HIL) test facility established at the Center for Advanced Power Systems at Florida State University.
