A wind turbine generator set, and a control method and apparatus for a wind power converter are provided. The control method includes extracting a super-synchronous oscillation component of a grid-side voltage of a wind power converter and a super-synchronous oscillation component of a grid-side current of the wind power converter. The control method also includes determining a phase angle of equivalent impedance of the wind power converter based on the super-synchronous oscillation component of the grid-side voltage and the super-synchronous oscillation component of the grid-side current. The control method further includes setting an operation mode of the wind power converter based on the super-synchronous oscillation component of the grid-side voltage and/or the super-synchronous oscillation component of the grid-side current, and the phase angle.

The present disclosure relates to a method of providing information for an on-demand service. The method may include: receiving service request information from a service requester. The service request information may include information relating to a location of the service requester; determining a candidate meetup location set based at least in part on the service request information. The candidate meetup location set may include at least one candidate meetup location; sending the candidate meetup location to the service requester; receiving processed data related to the candidate meetup location set by the service requester; and generating a processing result based at least in part on the processed data related to the candidate meetup location set by the service requester. Also disclosed is a system for implementing the method.
