The invention discloses a micro-grid multi-objective energy optimization method taking three-phase currents into consideration. The method includes the steps that a network reconstruction method is established so as to solve the problem of network losses of a micro-grid, and the network reconstruction method has good adaptability to the micro-grid. In addition, according to the situation that multiple asymmetric distributed power supplies are connected to the micro-grid and a large number of three-phase imbalance loads exist in the micro-grid and based on three-phase current calculation of the micro-grid and the network reconstruction method, a micro-grid unified coordinated optimization strategy taking active optimization of a whole system and the network losses into consideration is provided, total energy cost, the network losses and voltage deviation serve as multiple optimization objectives, and multi-objective energy optimization is converted into single-objective optimization through a subordinate function. Optimal energy distribution of the whole micro-grid is obtained through a particle swarm algorithm, energy optimization of the micro-grid is achieved, and good economic benefits are brought to power consumers.
