What is an energy microgrid?

A microgrid is a small electricity generation and distribution system containing distributed generation, energy storage systems, loads and monitoring and protection devices. It is an autonomous system that is self-controlled and self-managed. An energy microgrid provides users thermal energy for heating and cooling in addition to electricity.

How are microgrids transforming traditional electric power systems?

Traditional electric power systems are rapidly transforming by increased renewable energy sources (RESs) penetration resulting in more efficient and clean energy production while requiring advanced control and management functions. Microgrids (MGs) are significant parts of this transformation at the distribution level.

What happens when a microgrid loses power?

When the main electric grid loses power, the microgrid goes into island mode (i.e., operates independently of the main electric grid) and serves its own customers with the generation and other DERs (i.e., batteries or vehicle-to-grid electric vehicles) operating within the microgrid.

What is a microgrid control system?

Microgrid control systems: typically, microgrids are managed through a central controller that coordinates distributed energy resources, balances electrical loads, and is responsible for disconnection and reconnection of the microgrid to the main grid.
