The invention discloses a distributed photovoltaic power prediction method based on a space grid, the method comprises four steps of initial calculation, grid weather correction, environment correction and power generation plan correction, the method carries out distributed photovoltaic power prediction in the grid based on the information of the space grid where the distributed photovoltaic is located, and the power generation plan is corrected according to the unified rule of the space grid. Continuously segmenting a ground area according to a certain latitude and longitude or a ground distance, controlling the spatial uncertainty within a certain range to form regular polygonal grid units, and finally obtaining a distributed photovoltaic power predicted value in a spatial grid through the correction of the power estimated values in the steps 1-4. Through the method, the distributed photovoltaic power value at the future moment can be estimated more accurately. 本发明公开了的一种基于空间网格的分布式光伏功率预测方法，该方法包括初算、网格气象修正、环境修
