Hardware-in-loop Implementation of an Adaptive Droop Control Strategy for Effective Load Sharing in DC Microgrid

The recent trends of the power community is swiftly tending towards more flexible form of power generation for feeding sensitive loads like electronic and commercial loads. DC Microgrid is one of the solution to these emerging problems due to its efficiency, reliability and stability of the system. Many state-of-the art control strategies have been developed to achieve these goals. Load sharing and Voltage control is one of the major challenge in DC microgrid. Real-time hardware-in-loop (HIL) simulators enables the validation of theoretical complex control strategies applied to microgrid testbeds. This paper presents the hardware-in-loop (HIL) validation of an adaptive control strategy providing effective load sharing under various dynamic conditions in a DC Microgrid. Time-domain analysis of the power sharing on the DC Microgrid is performed using MATLAB/SIMULINK and it is validated by hardware-in-loop simulation on FPGA using Xilinx System Generator
