Abstract: The present disclosure relates to a simulation method and simulation apparatus for a wind farm common coupling region. The simulation method includes: obtaining main network data calculated in a previous simulation period as initial values for performing a main network simulation in a current simulation period; obtaining sub-network data of a sub-network corresponding to each wind farm which is calculated in the previous simulation period as initial values for performing a sub-network simulation in the current simulation period, in which the sub-network data of the sub-network corresponding to each wind farm comprises terminal voltage amplitudes of wind turbines and static reactive power compensation devices in each wind farm; performing the main network simulation and the sub-network simulation in parallel in the current simulation period.
