The development of social industrialization causes the problems of energy shortage. At present

the development and utilization of new energy has become an important component and the development direction of energy strategies. A DC power grid planning model based on wind and solar complementation is proposed. The DC power grid planning indicators with wind and solar complementation are defined

and a model based on the wind and solar hybrid grid planning is established. According to the secondary planning of DC power grid

the income index of wind and solar power generation is optimized

and the practical solution for the overheating problem of the cell is given. Experiment results show that compared with the traditional method

the DC power grid planning based on wind and solar complementation is more reasonable.
