6 FAQs about [The overall structure of the microgrid]
How are microgrids categorized?
Microgrids can be categorized via different aspects ranging from the structure such as DC, AC, or hybrid to control scheme such as centralized, decentralized or distributed. This chapter reviews briefly the microgrid concept, its working definitions and classifications.
What is the nature of microgrid?
The nature of microgrid is random and intermittent compared to regular grid. Different microgrid structures with their comparative analyses are illustrated here. Different control schemes, basic control schemes like the centralized, decentralized, and distributed control, and multilevel control schemes like the hierarchal control are discussed.
What is the layered structure of a microgrid?
The layered structure of the microgrid is explained followed by brief explanation of modes of operation, control, and hierarchical control scheme of the each microgrid. The concept and modeling of PV, MPPT algorithms, wind turbine system, batteries, and FC is also discussed.
What are the components of microgrid control?
The microgrid control consists of: (a) micro source and load controllers, (b) microgrid system central controller, and (c) distribution management system. The function of microgrid control is of three sections: (a) the upstream network interface, (b) microgrid control, and (c) protection, local control.
What are microgrid control objectives?
The microgrid control objectives consist of: (a) independent active and reactive power control, (b) correction of voltage sag and system imbalances, and (c) fulfilling the grid's load dynamics requirements. In assuring proper operation, power systems require proper control strategies.
