In recent years,Shanghai has complied with the needs of the national power systemreform and power grid development, implemented the approval spirit of the NDRC on developing the national demand side management demonstration project in Huangpu district, developed, constructed and operated the commercial building virtual power plant, and comprehensively carried out the virtual power generation practice. The background of developing virtual power plant is introduced. The application of key technologies of virtual power plant, the constructionof external operation platform, the design of internal control and interaction mechanism is expounded. The actual implementation and highlights of virtual power generation are summarized. The results and existing problems are analyzed. Some suggestions are put forward for further development in the future.
