What is a microgrid energy system?
Microgrids are small-scale energy systems with distributed energy resources, such as generators and storage systems, and controllable loads forming an electrical entity within defined electrical limits. These systems can be deployed in either low voltage or high voltage and can operate independently of the main grid if necessary .
What are isolated microgrids?
Isolated microgrids can be of any size depending on the power loads. In this sense, MGs are made up of an interconnected group of distributed energy resources (DER), including grouping battery energy storage systems (BESS) and loads.
Why are microgrids important?
Currently, there is substantial attention on microgrids (MGs) due to their ability to increase the reliability and controllability of power systems. MGs are a set of decentralized and intelligent energy distribution networks, which possess specific characteristics critical to the evolution of energy systems .
