In order to improve the transmission and distribution efficiency of urban distribution network,a three-level grid intelligent planning model based on greedy algorithm is proposed.The shortest path optimization method is used to construct the distributed power access model of urban distribution network and the transmission and distribution channel model of three-level grid in urba n distribution network.The node planning model of three-level grid in urban distributi on network is designed by using regular triangular network clustering protocol,a nd the confidence probability of routing conflict in three-level grid of urban distribution network is calculated.The node coverage energy information of three-level grid transmission and distribution channel in urban distribution network is extracted.According to the output power and voltage loss,the spatial planning of three-level grid in urban distribution network is carried out,and the global optimization of transmission optimization path is carried out by greedy algorithm.According to the global optimal solution,adaptive transmission and distribution scheduling is carried out,and the intelligent planning and design of three-level grid in urban distribution network is realized.The simulation results show that the proposed algorithm has better global dispatchi ng ability,higher transmission and distribution efficiency and better connectivity.
