Abstract: The power system has been developed from small capacity, short distance electric power grids to large-scale, wide area and multi-energy coupling energy networks. Power system development is pushed forward by the tendency of diversification, flexibility and intelligentization. Due to high similarity between the development of mobile communication technology and that of power systems, further researches on power system intergenerational differences are needed while the ‘G’ symbolled mobile communication technology (2G to 5G) has been well known. The ‘H’ symbolled power system intergenerational characteristic is proposed based on power system morphological features. After the voltage level of power systems has increased from 1H to 3H generations, the 4H generation power system with high proportion of renewable energy and power electronic equipment is started and gradually evolving to the 5H generation integrated energy system with high proportion of fragmented energy. In addition, the morphological features of and power grid enterprise orientation in the 5H generation are also discussed in detail.

Key words: power system, 5 H, fragmentation, diversification, integrated energy
