The invention discloses an energy storage system optimization operation method and system considering multi-mode fusion, and the method comprises the steps: obtaining photovoltaic output data and charging load data at each moment, and calculating the equivalent load efficiency at each moment according to the photovoltaic output data and the charging load data, forming an equivalent load power sequence based on the equivalent load efficiency at each moment; performing power smoothing processing on the equivalent load power sequence to obtain a grid-connected load power sequence after power smoothing processing; performing load shaping processing on the grid-connected load power sequence to obtain a target grid-connected load power sequence after load shaping processing; and calculating an energy difference between the target grid-connected load power sequence and the equivalent load power sequence, and balancing the energy difference based on a preset time-of-use electricity price mode. The power generation ef
