As new energy sources developing rapidly, there is urgent need to investigate the key technology of power grid planning under the new situation. This paper combs overall train of thought and work process of power grid planning, which allowing for the development of large scale new energy, and then, sums up major works and steps of network planning with new energy integrated into power grid. According to the actual requirements of power grid planning, the focus in this paper is on analyzing the issues below： output characteristics of new energy, influence of new energy integrated into power grid, operation assessment of power grid with large-scale new energy integrated, planning method of power grid with large-scale new energy accessed. The main problems and key technologies of power grid planning are analyzed and reviewed, pointing out the main targets for the future investigation.
