10 Microgrids
Microgrids are subsystems of the main grid. Microgrids consist of distributed generation, controllable loads, and storage. Microgrids are connected to the main grid through a single node. Microgrids also allow for more co-generation where excess heat from a generation facility can be sent to consumers who can utilize it. One approach to achieving an overall smart grid is to develop smart microgrids that are eventually all interconnected to form a smart grid. (Bakken, 214)
Benefits (Borlase 105)
- Voltage quality: Better able to compensate for reactive power
- Reliability enhancement: Increases overall reliability of grid since microgrids can be connected and disconnected from the grid as needed
- Optimized Generation: Better optimization of distributed generation since demand and supply can be better controlled
- Peak load shaving: the ability to better limit peak consumption which is the most costly power for a utility to generate.
- Energy loss reduction: Transmission losses are minimized since power is generated closer to consumers.
