Many technical problems have been solved and new problems are continuously appeared during the development process. And both pilot and commercialized micro-grids have been developed in many countries and areas in the world. (1) Please give an example of micro-grid demonstration projects and lists its features. (2) Some key technologies are still emergently necessary to make the micro-grid perfectly coordinate with distribution network and some other micro-grids. Can you summarize some important technical necessaries or trends of the micro-grids in the world? (3) What about the status of the renewable energies and micro-grid in your country? In your opinion, how to promote the development of micro-grids in your country?
