要約(英語): As the renewable energy sources (RESs) integration expands, the capacity of the synchronous generators (SGs) connected to the power system decreases. The Load Frequency Sensitive Mode (LFSM) has been proposed to improve frequency stability for RES-dominated systems by the active power generation or consumption proportional to the measured frequency deviation. However, the potential impact of the LFSM on power systems, including the damping performance deterioration of wide-area power swing oscillations, is a raised concern. In this study, the effects of the LFSM on the wide-area power swing oscillations are analyzed in detail based on the simulation waveforms using the IEEJ WEST 10-machine system model. Furthermore, the improvement of LFSM-induced power swing deterioration was validated by adjusting parameters of the Δω-type Power System Stabilizer (PSS) embedded in the SGs to adapt to a wide frequency range. These findings provide valuable insights for grid operators, policymakers, and vendors with the challenges of ensuring a stable and reliable power system while accommodating the growing integration of RESs.
