Effective coordination between collected and distributed renewable generation is one of the most important features for future smart grid in China. The distributed energy storage system（DESS） and mass energy storage system（MESS） will play significant roles in safely and stably connecting the enormous collected renewable generation（CDG） and distributed generation（DG） with the power grid. Based on a thorough analysis on the challenging problems for smart grid's compatibility， the coordinated dispatching is discussed taking into account the supply and storage property of the power grid. The CRG-MESS configuration for transmission and distribution power grid and the DG-DESS configuration for microgrid are proposed as a scheme for solving the compatibility of the future smart grid.
