Study of innovative impedance-based stability analysis for the power systems composed of inverter-based resources (ISAIPS–Impedance-based Stability Analysis on Inverter-based Power Systems)

The objective of this research is to analyse and control the impedance of distributed power supplies connected via power electronic (power electronics) devices and to prevent accidents caused by power system resonance phenomena. A laboratory-scale real micro grid (MG) will be constructed, and various constraints for impedance measurement will be clarified to establish procedures and methods. Furthermore, we will obtain guidelines on the amount of power supply impedance required for grid stabilization and robustness. This will enable power supply manufacturers and transmission/distribution companies to promptly enter the market and start operation by utilizing the results of this research when regulations on impedance analysis are introduced in the future.
