Description
Summary:The integration of renewable resources with low inertia, such as solar and wind, poses significant challenges to system inertia, stability, and crucially, system frequency regulation. While various emerging solutions like fast-responding storage facilities, short-term prediction and dispatching methodologies, and stringent operational regulations are being explored, many are still in the research phase. Despite this, the addition of renewable to the system continues to accelerate. The escalating system frequency issues pose a significant concern, particularly for critical machinery in the system, especially in hydro machines, which acts as recovery governors or droop governors. This paper proposes tuning the governor settings to mitigate unwanted movements and adjustments of the frequency-controlling governors, a consequence of system frequency changes primarily driven by renewable. The effectiveness of this proposed method is validated using the Sri Lankan power system as a real-world example, and simulated results demonstrate a noteworthy improvement compared to the existing system.
