This work develops an under-frequency preventive control strategy for island power systems that are based on evaluating the initial one-hour-ahead operating status of the system and a real-time correction method. The developed preventive control system evaluates initial system flexibility using a forecast of net load, it includes a low-frequency preventive control strategy to ensure stable operation...
With the development of renewable energy, many countries developed their projects in offshore islands, resulting in high penetration of renewable energy in those island systems. However, large renewable energy integration affects the original unit scheduling and system transient stability. When a contingency event occurs, such as a generator trip, the frequency stability would be reduced, even leading...
This work develops an under-frequency preventive control strategy for micro grid energy systems that are based on evaluating the initial one-hour-ahead system operating status and applies a real-time correction method. The developed preventive control system evaluates initial system flexibility based on a forecast of net load; it provides a low-frequency preventive control strategy to ensure stable...
