Robust control by a novel two-step successive solution approach to mitigate emergency frequency sag in power systems with modeling uncertainties

Key Points

• Frequency sag in power systems can lead to significant operational challenges, but this approach effectively mitigates it.
• The proposed two-step successive solution method significantly reduces frequency sag incidents by 30% compared to traditional methods.
• Assessment using control strategies demonstrates enhanced stability in power systems under varying modeling uncertainties.
• Further external validation is necessary to confirm the robustness of this innovative approach across diverse system conditions.
