Method and system for optimizing configuration scheme of power distribution network

The invention discloses a method for optimizing a configuration scheme of a power distribution network, which comprises the following steps of: carrying out regional division on the power distribution network needing to be subjected to configuration scheme optimization, and obtaining a load distribution value in a power distribution network region; calculating the total load distribution value of the power distribution network, and calculating and comparing the total load distribution value with the total load supply of the power distribution network; judging whether loads in the power distribution network are balanced or not; a primary adjusting signal is generated; the method comprises the following steps: acquiring circuit capacity and a line power flow coefficient between power distribution network regions, judging whether the line capacity in the power distribution network regions is stable or not, generating a secondary adjustment signal to adjust the power distribution network, and monitoring and calcu
