Microgrid

A Micro grid is a localized grouping of electricity generation, energy storage, and loads that normally operates connected to a traditional centralized grid (macro-grid). This single point of common coupling
with the macro-grid can be disconnected. The micro-grid can then function autonomously.Generation and loads in a micro-grid are usually interconnected at low voltage. From the point of view of the grid operator, a connected micro-grid can be controlled as if it was one entity. Micro-grid generation resources can include fuel cells, wind, solar, or other energy sources. The multiple dispersed generation sources and ability to isolate the micro-grid from a larger network would provide highly reliable electric power. Byproduct heat from generation sources such as micro-turbines could be used for local process heating or space heating, allowing flexible trade off between the needs for heat and electric power.
