Abstract :
The interest of distributed generations has been increased significantly now based on renewable resources in the world. This paper describes a kind of voltage control method of DC grid in distributed generations´ system. The proposed control method can autonomously realized that the DC grid voltage is set by the different voltage references with little communications in different conditions of loads´ power, the output power of renewable resources and the status of energy-storage units, and that the system power balance is maintained. The simulation results verify the performance of the proposed method.
