Frequency regulation analysis of modern power systems using start-stop peak shaving and deep peak shaving under different wind power penetrations

International Journal of Electrical Power & Energy Systems, 2021
Abstract Frequency regulation has attracted considerable attentions with the integration of large-scale renewable energy into power systems. The de-commitment of conventional units reduces the system inertia, thus causes the poor frequency performance under high wind power penetration.
