An online impedance analysis device based on CloudPSS-RT and RT-Lab co-simulation test bench

Abstract： High penetration of renewable energy in power grid challenges power system operation and stability evaluation, due to the fast dynamic behaviors of power electronic devices. The accurate broadband impedance measurement is one of the critical aspects of power system stability analysis. The impedance measurement method of injecting harmonics to the actual power system may bring the risk of instability. The hardware-in-the-loop simulation technology can achieve accurate broadband impedance measurement with lower cost and risk. The computing accuracy and simulation scale of real-time simulators depend on the computing power of the target computer. As the demands of large-scale power system increase, a single real-time simulation system may not meet the requirements. Co-simulation between multiple real-time simulators is an effective way to increase the scale of the simulation. This paper proposed an online impedance analysis co-simulation framework based on the CloudPSS-RT and RT-Lab platform and verified the accuracy and effectiveness of the co-simulation by constructing a PV and DFIG power generation system.
