Description

technical field

[0001] The invention belongs to the field of electric power system automation, and in particular relates to a power supply path analysis method and system based on graph calculation. Background technique

[0002] With the rapid construction and development of the global energy Internet, the rapid development of new energy and diversified loads, the structure and operation mode of the power grid are becoming more and more complex, the dispatching control of the power grid is gradually extended to the low voltage level, there are many distribution network equipment, and the network structure is mostly ring Therefore, the topological relationship of the power grid is particularly complex. The challenges encountered in power grid topology analysis are as follows: 1) With the extension of the voltage level of dispatch management, the involved grid equipment increases exponentially, resulting in a geometric growth of power grid topology analysis data; 2) With the r...
