Synchronous Condenser Site Selecting Method for Reducing the Trip-off Risk of New Energy Generators

摘要

Focusing on the problem of new energy units tripping under power grid disturbance, a synchronous condenser site selecting scheme in the new energy sending system based on quantitative evaluation method is proposed in this paper. In this method, the quantitative evaluation index of reducing the new energy trip-off risk when the synchronous condenser applied to the network is calculated. In the index, the economic loss of new energy generators trip-off and the probability of grid faults is considered. And then according to the quantitative index, the priority of synchronous condenser sites is determined. Finally, the effectiveness of the method is verified by an actual power grid example.
