6 FAQs about [Structure of microgrid control device]
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.
Are hierarchical control strategies applied to microgrids?
This paper reviews the status of hierarchical control strategies applied to microgrids and discusses the future trends. This hierarchical control structure consists of primary, secondary, and tertiary levels, and is a versatile tool in managing stationary and dynamic performance of microgrids while incorporating economical aspects.
What is a microgrid controller?
These controllers are responsible to perform medium voltage (MV) and low voltage (LV) controls in systems where more than single microgrid exists. Several control loops and layers as in conventional utility grids also comprise the microgrids.
What is microgrid control infrastructure?
A microgrid control infrastructure is composed of a number of central and distributed controllers. The central controllers are connected to MGCC to improve and enhance operation features of microgrid. The MGCC determines demand power, enhancement conditions and load capacities considering the auxiliary services of distribution system.
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.
