Özet

This paper contributes to the fast detection of control interaction risk in a PV park using the eigenvalue analysis in Modelica. The entire PV park and its interconnected network are represented by time-domain equations in Modelica, then linearized state space equations are extracted directly by leveraging the Modelica features. This constitutes an advantageous approach for fast finding eigenvalues and extracting potential instability conditions. The presented approach is verified with electromagnetic transient (EMT) simulation and impedance-based stability analysis (IBSA) that uses EMT-type impedance scanning methods. The results show an outstanding improvement in the simulation time and accuracy.
