RT-LAB based real-time simulation of photovoltaic power generation system

This paper presents a single-stage grid-connected photovoltaic(PV) system,using the photovoltaic array simulator instead of the traditional solar photovoltaic cells.The Real-time simulation model based on the RT-LAB software platform has been built.It can neglect the limits of real conditions of the PV experiment in the laboratory.At the same time,it takes the hardware environment into account to fetch up the shortage of all-digital simulation platform.It provides a good simulation platform for the high-power in a real or near real-environment for the labora-tory photovoltaic research.
