The invention relates to the technical field of photovoltaic energy storage, and discloses a method for optimizing operation of an energy storage system of a light storage type charging station, and the method comprises the following steps: 1, carrying out the charging judgment of a vehicle; step 2, optimizing charging distribution; step 3, energy storage optimization; step 4, load optimization; 5, a multi-objective optimization model is established; and 6, real-time scheduling and feedback are carried out. According to the invention, the system preferentially uses the power of the power grid for charging in the valley period with low electricity price, thereby improving the utilization rate of the power grid, reducing the pressure of the power grid in the tip period and the peak period by reasonably allocating the charging power of the power grid and photovoltaic energy storage, and reducing the charging power of the power grid in the tip period and the peak period. The system can effectively reduce the load pressure of the power grid, avoids the impact on the power grid caused by excessive power consumption in the peak period, and achieves the beneficial effect of improving the load of the power grid side and the energy storage side at the same time by dynamically adjusting the charging power proportion # imgabs0 # of the power grid and smoothing the load curve of the power grid.
