Xinhua News Agency, June 16, Zuo Juan, director of the virtual power plant and transaction technology research office of the State Grid Shanghai Energy Internet Research Institute, said at the visible Research Institute forum today that the construction of virtual power plants can be divided into three stages: invitation type, market type, and cross-space independent scheduling type. At present, Jiangsu, Anhui, Guangdong and other places have carried out pilot projects of power demand response and virtual power plants, while Zhejiang, Shanghai and North China have participated in the market under the condition of relatively good electricity market construction and are in the market-oriented stage. "the form of interaction between large power grid and microgrid in the future may be a direction of the development of our power grid." finally, the virtual power plant will achieve the combination of local balance and large network dispatching, and enter the stage of cross-space autonomous scheduling. She revealed that the national standards for virtual power plants are being declared. "the international standards have been drafted and are now being voted," but the standard has been written for 18 months. Coupled with the time for examination and approval, "the real national and international standards may not come out for another two years." (financial Associated Press reporter Xu Haidong)
