Summary: | This application provides a power system and a control method for a power system. The power system includes a primary controller and N direct current coupling units. The N direct current coupling units are configured to provide electric energy to a load. Each of the N direct current coupling units includes an energy storage unit. The energy storage unit is configured to store electric energy or supply power to the load. Herein, N is a positive integer. The primary controller is configured to: determine an expected discharge power value of energy storage units in the N direct current coupling units, where the expected discharge power value is a power value that indicates power that needs to be discharged by the energy storage units in the N direct current coupling units; and determine actual discharge power of the energy storage unit in each direct current coupling unit based on the expected discharge power value and first characteristic information of the energy storage unit in the direct current coupling unit, where the first characteristic information indicates a real-time charging/discharging capability of the energy storage unit in each direct current coupling unit. In this way, the actual discharge power of the energy storage unit in each direct current coupling unit can be properly allocated, to improve running reliability of the power system. |
