R3, in organic growth area, urban planning wouldn't be defined, can not determine the grid of load growth point, according to power supply
Status power grid assessment result in unit, emphasis solve power grid outstanding problem, promote short slab index, and combine load development,
Construct the standards wiring such as Single-ring network, three segmentations, two contact or simply connected network.
10. a kind of active gridding planing method based on distributed generation resource access according to claim 1, feature exist
In: in step S6, analyze active gridding planning investment and Effect on construction in project period, comprising:
P1, list active gridding construction project, to construction project carry out investment estimate, list needs subitem investment and
Gross investment, wherein to being listed year by year in the recent period；
P2, analysis power distribution network the status key technical index of problems for solving situation, active gridding construction；
The economic benefit that P3, the active gridding of analysis are built；
The social benefit that P4, the active gridding of analysis are built.
