Adaptive Energy Management in Redundant Hybrid DC Microgrid for Pulse Load Mitigation

  title={Adaptive Energy Management in Redundant Hybrid DC Microgrid for Pulse Load Mitigation},
  author={Mustafa Farhadi and Osama A. Mohammed},
  journal={IEEE Transactions on Smart Grid},
This paper investigates the real-time control and energy management of a dc microgrid incorporating hybrid energy sources with various loading schemes. In the proposed dc microgrid, a supercapacitor bank, a power buffer, and a pulse load are directly connected to a dc bus. The proposed system configuration highly improves the grid redundancy and reduces the total power losses. Moreover, the supercapacitor bank not only supplies the pulse load, but also supports the grid during transient periods… Expand
