What is microgrid configuration & control objectives?

The microgrid configuration and control objectives impose a variety of requirements on the communication system to ensure different delivering times for various signals generated both inside and outside the microgrid.

Does a microgrid need a communication system?

This necessitates a dedicated communication system for microgrid operation. Consortium for Electrical Reliability Technology Solutions (CERTS) has established that a without communication microgrid structure is a desired microgrid structure.

What is a microgrid control system?

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.

Can a microgrid operate in autonomous mode?

However, a microgrid operating in autonomous mode will only operate when voltage and frequency stabilization condition is met. To achieve the required control, a droop control or hierarchical control is employed. Subsequent sections discuss different architectures of microgrid and relevant control strategies.

How a microgrid is connected to a grid?

Depending upon the mode of operation, an autonomous microgrid is connected to AC loads through AC bus. A microgrid operating in grid-tied mode is connected to main grid through AC bus where local AC loads are also connected . Fig. 2.2 presents the schematic diagram of AC microgrid structure. Figure 2.2. AC microgrid structure.

What is microgrid management level control?

An economic operation of microgrid requires optimal generation from different microsources. This task is also performed at management level control . 3. Grid level control: This is the outermost control layer in hierarchical control scheme, in which several microgrids operating in parallel are managed and coordinated.
