With the integration of large-scale，intermittent generation sources and highly-permeable distributed generation connected into grid，load characteristics are becoming more complex.As a carrier that connects the power generation and load，the grid itself is becoming increasingly large in scale and confronted with growing pressure on the security and stability of operation.To build a safe，stable，efficient and economical smart grid is now the objective of Chinas grid development.In the light of the concept of goingenvironmentally friendly”，the concept of goinggrid friendly”is proposed and is receiving ever-increasing recognition as an important component part of smart grid research.The connotation of grid friendly technology is analyzed，which is seen as the coordination and interaction between the generation or electrical equipment and the power grid in support of the safe and economical operation of the grid.A summary of the existing grid friendly technology of the generation side and power-use side shows that the main technology of the generation side consists in enhancing the predictability，stability and controllability of new energy power generation while that of the power-use side is adopted to improve the characteristics of the load and study the supporting technology.Based on the above，an analysis is made of some new ideas of grid friendly technology development in the framework of smart grid，and a long-term development framework is proposed.
