Electricity produced by the microgrid is distributed to end users, such as households, businesses, and other facilities, to meet their energy needs. It can power various devices, machinery, and appliances. Many solar microgrids have the capability to connect or disconnect from a larger grid as needed.
Microgrid is an important and necessary component of smart grid development. It is a small-scale power system with distributed energy resources. To realize the distributed generation potential, adopting a system where the associated loads and generation are considered as a subsystem or a microgrid is essential.
Energy Management: Microgrids need a system to manage the flow of energy, ensuring that energy is being used efficiently and effectively. This includes monitoring and controlling the mix of energy sources, as well as balancing the energy supply and demand.
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.
