Abstract
This paper presents a Component Connection Method (CCM)-based harmonic stability analysis for ac power-electronic-fed power systems. In the approach, the system is partitioned as individual components, including the controllers of DG units, LC filters, network impedances, and power loads. They are first independently modeled and then assembled together based on component interconnection relationships, forming a composite system model featured with the sparse and diagonal state matrix, and thereby reducing the computational burdens. A modular modelling technique for inverter-fed power system is formulated. And the harmonic stability is assessed based on eigenvalue traces of the composite model. Simulations and experimental results are given to validate the effectiveness of the analysis method, which can be employed to assess the system harmonic stability for any combinations of system parameters
