Research on DC Microgrid Simulation for Marine Energy and Implementation of RT-LAB Semi-physical Simulation

Abstract

Digital simulation such as MATLAB/Simulink is mostly used to study the control algorithm of DC microgrid system, but the operation of microgrid system cannot be simulated realistically. Firstly, control strategy of DC microgrid is developed and verified in this paper, then RT-LAB is used as a hardware-in-the-loop(HIL) simulation platform to realize a connection with the controller. Finally, a HIL simulation platform of 2KW DC microgrid for marine energy generation is built. The proposed method can greatly shorten the development cycle and cost of DC microgrid system for marine energy.
