Hierarchical Control of DC Microgrid
Abstract: This work presents an extensive review of hierarchical control strategies that provide effective and robust control for a DC microgrid. . High penetration of Renewable Energy Resources (RESs) introduces numerous challenges into the Microgrids (MG), such as supply–demand imbalance, non-linear loads, voltage instability, etc. Hence, to address these issues, an effective control system is essential. DC microgrid is an efficient, scalable and reliable solution for electrification in remote areas and needs a reliable control scheme such as hierarchical. . Depending on the time and bandwidth requirements, microgrid controllers can be categorized to primary local controllers (LC) and secondary microgrid central controllers (MGCC).
