To quantify the support capability of multiple types of flexible resource for the planning and operation of pow⁃er grid,an evaluation method for user-side flexible resource response potential based on regional grid is proposed.First,a flexible resource response potential evaluation framework and the corresponding evaluation indexes are de⁃signed.Then,based on the idea of optimal operation under time series simulation,a time series potential evaluation model considering the interactions between flexible resources and power grid is constructed and further solved by an op⁃timization software package.Finally,the validity of the proposed evaluation model and method is verified by an actual example.Results show that the potential of user-side flexible resource is huge,and it is necessary to make full use of the support capability of massive flexible resources in distribution network planning in the future.
