What does a microgrid control system include
A microgrid control system (MCS) is the central intelligence layer that manages the complex operations of a localized power grid. This system integrates diverse power sources, such as solar arrays, wind turbines, and battery storage, collectively known as Distributed Energy. A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. SEL control hardware works with almost all distributed energy resource (DER). A microgrid solar system is a localized energy network that uses solar panels as its primary power source, combined with battery storage and intelligent control systems, capable of operating independently from the main electrical grid when needed. Microgrids provide independent power - when the traditional power grid goes out, a microgrid can immediately switch to backup generators and batteries.
