With the rapid development of new energy generation, the uncertainty and randomness nature of new energy generation brings about profound influence to the conventional power grid planning. Therefore, it has practical significance to establish a power grid planning method adapt to the integration of large-scale new energy generation. This paper combines the new energy accommodation with the grid planning process and proposes a power grid planning method aiming at accommodating new energy efficiently and effectively. Based on the technique of system operation simulation and the technique of new energy accommodation capability evaluation, this method could estimates all the alternative power grid planning schemes and selects the scheme which satisfies both the demand of accommodating new energy and the need of system optimal operation. Finally, this paper carries out a case study of Guangdong power grid to verify the reasonability and effectiveness of the proposed method.
