abstract
In this paper, a novel PWM carrier synchronization method is proposed for distributed DC–DC converters in DC-Microgrids. The synchronization method is based on carrier frequency extraction from DC-bus voltage ripple. In addition, an advanced phase shift control algorithm for the synchronized carriers is implemented to reduce the DC bus voltage ripple contents. A DC-Microgrid encompassing different distributed energy resources with their DC–DC converters is modeled using Matlab\Simulink to test the proposed synchronization method and control algorithm. Then, a small power scale experimentaltestbed is built in order to validate the simulation results. The simulation and the experimental results demonstrated that the proposed method and algorithm are very promising to minimize DC-bus ripple contents in DC-Microgrid applications.
6. Conclusion
In this paper, a new PWM carrier extraction based synchronization scheme for distributed DC–DC converters in DC-Microgrids is presented. Then, a phase shift control algorithm for synchronized PWM carrier is implemented to minimize the DC bus voltage ripple magnitude. A DC microgrid model encompassing three DGs with their DC–DC converters is used as a prototype to test the proposed synchronization method and DC-bus ripple minimization algorithm based on Matlab\Simulink. The simulation results show that proposed methods have the ability to generate adapted PWM carriers in order to decrease the DC-bus voltage ripple by more than 70%. In addition, a small power scale experimental test-bed has been built in order to test the proposed methods and validate the simulation results. Experimental results have also demonstrated that the proposed method is very promising to minimize ripple contents of DC–DC converters that are interfaced to the DCMG’s DC-bus.
