The spatial load of multi-power distribution network is easy to overload,which leads to the reduction of distribution network planning stability. A dynamic planning and optimization method of multi-power distribution network considering the spatial load layout was proposed. According to the equivalent topological circuit structure of multi-power distribution network,the constraint parameters of dynamic planning of multi-power distribution network were analyzed and processed. Combined with the spatial load balancing node,the spatial load was balanced and scheduled by fusing the zero mode wave velocity parameters of the line. Active and reactive power coordinated control was adopted to optimize and analyze the dynamic constraint parameters such as transmission delay and wave impedance,thus to realize the dynamic planning optimization design of multi-power distribution network. The experimental results show that the dynamic planning of multi-power distribution network considering spatial load layout has better output parameter steady-state tracking performance,smaller output deviation,shorter planning time,lower planning cost,higher planning quality and better practical application effect.
