Abstract: | To achieve the carbon peaking and carbon neutrality goals, new energy devices are widely connected to the power grid, which creates impedance mismatch and small signal instability problems. Aiming at the lack of suitable experiments for the DC/DC converter dynamic modeling and impedance analysis, this paper explores a novel experimental platform design and corresponding analysis method. It not only guides students to understand the application of dynamic modeling, but also grasp the impacts related with parameters, measurement and algorithm. Finally, the impedance design and matching research capability in practical project get enhanced. |
