Implementation of a Photovoltaic Array Simulator Based on a Virtual Instrument and a Lab Programmable Power Supply

Resumen: This paper shows the integration of a control system based on a virtual instrument that controls a laboratory power supply through a data acquisition card. The system emulates the performance of photovoltaic arrays where each element can be set to different levels of irradiance. Algorithms superpose the response curves interpolated by the Sandia simplified model, simulating partial shade conditions. Since the developed simulator uses general-purpose equipment, it could be a useful tool to test photovoltaic inverters in a flexible and inexpensive way with a performance like specialized equipment.
