6 FAQs about [Microgrid structure and parameters]
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 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.
What are control strategies in microgrids?
Control strategies in microgrids are used to provide voltage and frequency control, the balance between generation and demand, the required power quality, and the communication between microgrid components.
What is microgrid hierarchical control?
Figure 1 shows the principle of microgrid hierarchical control, which can operate islanded as well as grid-connected, and combined heat power (CHP), photovoltaic system (PV), wind power system, and energy storage system (ESS), etc., and can be used as the basic unit of a microgrid power generation system.
What are the enabling technologies for microgrids?
In a refreshingly simple way identifies the enabling technologies for microgrids, that is power electronics, communications, renewable resources. It discusses in simple terms the ability of microgrids to minimize green house gases, help the power grid with load balancing and voltage control and assist power markets.
