A real-time co-simulation of PV power generation system using transmission line model interface

Abstract

The real time co-simulation has been greatly developed all over the world. Through an interface that can enable the information exchange between two simulators, the co-simulation can synchronously simulate a large complex system. The objective of this paper is to present a real time co-simulation test bench using RT-Lab and CloudPSS-RT for analyzing the PV power generation system. The system structure, network partitioning methods, and the averaged modeling methods of the PV system are proposed in this paper. Through simulation results accuracy test and frequency-sweeping test, the accuracy and effectiveness of the co-simulation is verified.
