Power Management Strategy for a Direct Current Hybrid Microgrid based on Doubly Fed Induction Generator and Fuel Cell

In recent years, renewable energies tended to integrate the electricity production grid at different levels, and have become a crucial solution to help mitigate the harmful effect of greenhouse gases and reduce the energy dependence of countries in terms of electricity. Microgrids give a good option to implement these resources in a decentralized manner and expand the electrical grid consistency. In this paper we will model a DC hybrid microgrid combining both Fuel Cell (FC) and Doubly Fed Induction Generator (DFIG) based Wind Turbine (WT) technologies. This microgrid is intended to be capable of guaranteeing the electricity procurement continuity despite of variable load demand and the intermittency aspect of the wind resource. The adopted Power management strategy and controls were emphasized, and the obtained results from MATLAB/Simulink simulation tool support and endorse the presented strategy.
