Abstract
Active damping method and load current feedforward control method has been studied for control dc bus voltage in DC microgrid. Since load current feedforward control method requires information through communication, performance of controller is affected by communication time delay. This paper analyzes time delay performance of DC bus voltage variation with four control strategies based on the two control methods. DC bus voltage variation with four control strategies are simulated and analyzed considering three time delay cases.
