Abstract

DC Microgrid has drawn more and more attention in the distribution system as it is easier for connecting DC sources and loads. This paper presents a layered control strategy with three levels for regulating the voltage and balancing the power for DC Microgrid consisting of different kinds of distributed generations and loads. DC voltage value is defined as a signal to change the control mode, and each converter operates independently without the need to communicate with each other. Therefore, the configuration of DC Microgrid is simplified. The validity of this control strategy is simulated through PSCAD under different operating conditions, such as changing the wind speed, the irradiation, and the load value or main grid failure case. From analyzing the simulation result, it can be seen that this layered control strategy is effective, and every converter responds quickly and correctly to the variation.
