Abstract:The exploitation of new energy has been global trend and common task through the world in recent years, which will deal with energy crisis and environmental pollution. Solar energy technology, wind energy technology and other new energy technology has appeared and developed rapidly in this situation. Most of these new energy resources will be transformed to electricity and join into the power system, which will raise all kinds of safety problems. In order to consume new energy, the power grid has to be updated to smart grid which is more steady, flexible and compatible. Having presented the status and development trend of new energy, the differences between new energy and traditional energy are proposed. Despite of the advantages of new energy, the safety problems in power grid caused by new energy are illustrated in detail. Thence the self-healing of smart grid is important to the development of new energy. And the present situation and key technologies of self-healing are introduced. With self-healing and new energy, smart grid will be further updated to energy internet. Energy internet will bring sharing economy mode into resource and power areas, which will also support the utilization of new energy.
