Abstract

This paper presents a reduced-order modelling method for grid-connected inverter with long transmission cable (LTC). State-space models of inverter and LTC are first obtained from frequency characteristics of terminal impedance by applying vector fitting (VF) algorithm rather than conventional mathematical modelling. Then, Prony analysis (PA) and balanced truncation (BT) algorithms are employed to find an optimized order number of state-space model. Finally, a reduced-order model of grid-connected inverter with LTC is established by removing non-dominant poles of original state-space model. Simulation results show that the proposed reduced-order modelling method is able to accurately obtain dominated poles of system, and reveal practical terminal impedance characteristics. The proposed method may simplify modelling procedure and improve computational efficiency for small signal stability analysis.
