Phase commutation method and system for three-phase imbalance treatment, storage medium and equipment

The invention discloses a phase commutation method and system for three-phase imbalance treatment, a storage medium and equipment, and the method comprises the steps: obtaining the load distribution information of a user side in a power distribution area, and determining a plurality of positions where the load change of the user side is greater than a change threshold value; according to the load distribution information, determining line currents of all the phase-change switches in the power distribution area, and determining a state matrix of phases accessed by all the phase-change switches; modeling is carried out on the three-phase unbalance degree of a plurality of phase-change switches in the power distribution area and the number of phase-change actions of the phase-change switches; iterative optimization is carried out through a discrete particle swarm algorithm to output an optimal commutation strategy; and controlling a plurality of commutation switches at the user side in the power distribution are
