摘要：The paper analyses possible strategies of maintaining a required inertia level by individual control blocs/areas in synchronously connected power systems.These strategies take into account the possible (significantly probable) divisions of a large system into asynchronous,unbalanced subsystems.The analysis includes different values of the allowable rate of change of frequency (RoCoF) in individual units and specific RoCoF statistics (other than maximum).These strategies require solving properly defined optimization tasks.
