Hierarchical Control Strategy for Microgrid

As a new type of complex hybrid energy system energy internet system (EIS) has become the focus and hot spot in the field of energy and academia at home and abroad. As an important part of the energy Internet, the micro grid can be flexible and stable operation, which will be a challenge to the reliability of the energy internet. Aiming at the micro grid operation control problem, this paper lists the commonly used hierarchical control strategies in recent years, and analyzes and compares them one by one. Finally, the possible research directions in the future are discussed.
