Grid-based power distribution network upper and lower combined investment method

The invention relates to a grid-based power distribution network upper and lower combined investment method. According to the method, a power distribution network investment distribution model from top to bottom and a power distribution network investment optimization model from bottom to top are combined on the basis of grids, so that various plans are organically connected, planning project arrangement is scientific, reasonable and orderly and is not repeated or missed, the weak problem of a power grid is accurately solved, and finally accurate investment of the power distribution network is realized. 本发明涉及一种基于网格的配电网上下结合的投资方法。该方法基于网格将自上而下的配电网投资分配模型和自下而上的配电网投资优选模型相结合，使得各项规划有机衔接，规划项目安排科学合理有序，不重不漏，精准解决电网薄弱问题，最终实现对配电网的精准投资。
