Advancements in technology, economic challenges, and impacts of environment demand distributed generation rather than centralized conventional generation. Use of distributed generation alleviates pressure from the main transmission system. But due to intermittent renewable generation, there are a number of technical issues in distributed generation, as it can affect the quality of power in utility grids. Microgrid was introduced to meet the uneven behavior of distributed generation and surging their use. DC microgrids are popular as in DC output sources such as wind mills and photovoltaic systems; there is no necessity of conversion devices, and thus efficiency is improved. However, in real time, some issues have to be met for the installation and proper working of DC microgrids. This paper presents, a multilevel control structure which guarantees control of a DC microgrid in an efficient manner. A case study implementing a DC microgrid having PV arrays, BESSs, wind mill, and AC grid is also presented. The voltage of DC bus obtained is kept constant using proportional–integral (PI) controller.
