In order to ensure the secure and safe operation of DC microgrids, different control techniques, such as centralized, decentralized, distributed, multilevel, and hierarchical control, are presented.
The first challenge in regulated DC microgrids is constant power loads. 17 The second challenge stems from the pulsed power load problem that commonly occurs in indoor microgrids. The pulsed loads in the microgrid limit
A detailed review of the planning, operation, and control of DC microgrids is missing in the existing literature. Thus, this article documents developments in the planning, operation, and
With the advancement of technology and human movement towards evolution, intelligent control methods are becoming more important. One of the areas of progress is related to the development of new frameworks for
In order to achieve optimal grid performance and integration between the traditional grid with microgrids systems, the implementation of control techniques is required . Control methods of microgrids are commonly based on hierarchical control composed by three layers: primary, secondary and tertiary control.
The control techniques developed in various research works for intelligent microgrid implementation are usually based on control strategies. Besides, a microgrid controller requires accurate data for a better performance index to ensure the efficiency of the power network.
An innovative microgrid operation requires hierarchical coordination with different technologies to control and estimate various variables and parameters in a real-time environment, regardless of the system complexity, types, and structure.
Without the inertia associated with electrical machines, a power system frequency can change instantaneously, thus tripping off power sources and loads and causing a blackout. Microgrid control systems (MGCSs) are used to address these fundamental problems. The primary role of an MGCS is to improve grid resiliency.
The architectural selection of a given control technique considers the design ability to handle the control strategies of microgrids. The estimation techniques of the microgrid variables and parameters deal with the measurement and monitoring system to accurately reinforce the dynamic performance of control techniques .
Hence, the main concern in the operation of the microgrid is to control the power electronics units. Microgrid's control methods are different with respect to its structure that is mean that what type of microgrid exist for study, DC or AC microgrid or consolidation of them that is called hybrid microgrid.
