Online optimization method for intelligent soft switch of low-voltage power distribution network

An intelligent soft switch on-line optimization method of a low-voltage power distribution network comprises the following steps: establishing a flexible air conditioning equipment model constraint equation, replacing a traditional switch with an intelligent soft switch, and constructing an intelligent soft switch operation constraint equation suitable for power distribution network operation state optimization; a target function is established by taking improvement of economic benefits of the power distribution network and reduction of voltage deviation degree as targets. Through absolute value linearization and second-order cone relaxation, a power distribution network intelligent soft switching optimization problem considering the flexibility of the air conditioning equipment is converted into a mixed integer second-order cone programming problem, and a CPLEX solver is adopted for solving, so that the operation loss of the power distribution network can be reduced, and the economical efficiency and the vol
