In the midst of clean

low-carbon and smart energy revolution

a high proportion of renewable energy integration will be one of the basic characteristics of future electric power system that leads to tremendous changes in the morphological changes. And it also introduces the morphological evolution of generation

transmission

distribution and load of the system as a whole. The topology evolution model and power forecasting method of the future electric power systems are reviewed. The elements of the electric power system morphology and driving model are described first. Then based on analyzing the development trend of high proportion renewable energy generations

a future power system morphological evolution model is proposed. Key scientific issues are concluded as: 1)morphological evolution mechanism of power system with a high proportion of renewable energy; 2)power forecasting of complex multiple uncertainty operation scenarios. Suitable research framework is divided into four aspects and analyzed in detail.
