An emulated PV source based on an Indoor Solar Panel with external excitement current and voltage compensation

This paper presents a novel emulated photovoltaic (PV) source that was constructed by using an indoor solar panel and an external current and voltage source. The mathematical model and electrical characteristics of the emulated PV source were defined and analyzed in detail in the paper. Measures for eliminating the errors of the emulated PV source was also proposed and demonstrated by experiment. The constructed PV source has the advantages of high bandwidth over the switching circuit-based PV simulators. The constructed PV source has used for testing various power electronics converters and various control techniques effectively in laboratory environments for researchers and university students.
