| description | The invention discloses a power transmission network redundancy constraint identification method and system, a medium and equipment, and the method comprises the steps: carrying out the conservative estimation of a power flow limit in the actual operation of a power transmission line under a given load level, a new energy prediction result and an uncertainty error through solving a plurality of optimization sub-problems; lines which do not need to add load flow upper limit constraints and are not overloaded are eliminated to effectively reduce the constraint scale, and the aim of improving the solving efficiency is achieved. The method has good parallel computing potential, computing resources of hardware equipment can be fully utilized, ineffective network transmission constraints, especially redundant load flow upper limit constraints corresponding to a power transmission network in a large-scale power system, can be correctly recognized and eliminated, the problem scale is reduced on the premise that corre |
