Abstract :
This paper demonstrates the validation and performance testing of a decoupled controller for a single phase single stage rooftop PV by its hardware in loop (HIL) implementation. The designed controller was programmed in a digital signal controller. The rest of the system placed in real time simulator i.e. OP5600 HIL box from OPAL-RT. By the help of asynchronous communication between the plant in HIL box and controller in the microcontroller the whole system was implemented. For various operating conditions the system results are studied and reported in this paper. The effect of grid conditions on the controller behavior also analyzed.
