The invention discloses a multi-train speed curve collaborative optimization method considering network loss. The method comprises the following steps: acquiring basic data of trains, lines, timetables, traction networks and the like; calculating an energy-saving speed curve of a preceding train running in each section, introducing a posterior train, dividing the running process of the multi-trainsystem into sub-sections, establishing a traction network equivalent circuit model based on multiple trains, establishing and solving a traction substation total energy consumption optimization model, and outputting a multi-train energy-saving optimization speed curve. According to the invention, the running speed curve of a single train in each section is optimized such that train traction energy consumption is reduced, the utilization rate of regenerative braking energy is increased by cooperatively optimizing speed curves of multiple trains, single-train optimization and multi-train optimization are combined, meanwhile, train traction energy consumption is reduced, the utilization rate of regenerative braking energy is increased, and finally the total energy consumption of a traction substation is reduced.
