Abstract: With the increasing penetration of large-scale wind and PV power within the power system，theywill inevitably participate in the load frequency contro（l LFC）. Since the power output of wind and PV is unstable，which would affect the power balance of grid，thus cause unstable frequency. A LFC method based on d...
