Abstract: Due to the inaccurate power deviation and network loss results obtained by the energy storage power

control of the multi-source distribution network，the power control results are not ideal. A rational control method of energy storage power in multi-source distribution network based on ant colony algorithm was proposed，and the

energy storage architecture was designed，which is composed of energy storage controller，photovoltaic controller，wind controller and other equipments. The operation characteristics of energy storage in multi-source distribution network were analyzed. According to the characteristics，with the goal of minimizing the sum of operating costs and resource depreciation costs，a rational control model of energy storage power in multi-power distribution networks was constructed，and the model was optimized and solved by ant colony algorithm to achieve rational control of energy storage power. Experiments show that the proposed method does not experience overvoltage and undervoltage，the network loss value is only 85.5 kW·h，the three-phase unbalance is 0.18%，and the power deviation is 29.4W. Therefore，the proposed method effectively improves the power control effect.
