Schematic diagram of the composition of a smart microgrid

What is a smart microgrid?

Smart microgrids (SMGs) are small, localized power grids that can work alone or alongside the main grid. A blend of renewable energy sources, energy storage, and smart control systems optimizes resource utilization and responds to demand and supply changes in real-time 1.

What is a microgrid model?

Background of Microgrids Modeling 3 Microgrids as the main building blocks of smart grids are small scale power systems that facilitate the effective integration of distributed energy resources (DERs). In normal operation, the microgrid is connected to the main grid.

What are the components of smart-grid system?

This chapter discussed the various components of smart-grid system, which together develop the smart-grid system. These components include smart appliances, electric vehicles, smart substations, smart meters, distributed generation, Phasor measurement units, integrated communication, and sensing and measurement techniques.

What are the strategies for energy management systems for smart microgrids?

There are many strategies for energy management systems for smart microgrids such as load management, generation management, and energy storage management 4. The control system of a microgrid must continuously analyze and prioritize loads to maintain a balance between power generation and consumption.

What are the components of a microgrid?

The considered microgrid in this article is composed of multiple components, which are associated with renewable power sources (solar, wind, etc.), energy storage devices (battery banks), loads, and the connection with the utility grid for exchanging energy.

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.
