Abstract:
In modern power systems, the frequency can deviate from its nominal value due to imbalances between generation and demand. Abnormal frequency can cause generator trips and blackouts, resulting in significant economic losses. To regulate frequency deviations, power system operators must schedule sufficient frequency regulation resources, such as inertia and frequency regulation reserves provided by online generators. However, improper generator maintenance schedules can reduce the availability of these resources, increasing the risk of power blackouts. We propose a robust generator maintenance scheduling model incorporating frequency security constraints to ensure proper maintenance scheduling while hedging against various uncertainties in power systems and develop a hedging-based algorithm and a duality-free cutting-plane method to solve it efficiently. Additionally, we introduce a novel frequency security criterion based on cumulative frequency deviation. This criterion can evaluate the performance of frequency regulation resources with different response speeds, enhancing the planning and resource allocation of power systems.
