Question

What is the difference between microgrid and smart grid in table form?

Answer 1

Micro grid is a localized system where energy is produced mostly locally, and/or also taken from grid for a very small area for a locality. In case of any difficulty, the micro grid can be separated from main grid and keeps operating independently. This is very convenient at local level with solar energy, or for integration of solar or wind energy at local level with larger main grid.

Smart grid is a combination of micro and mini grids, and has fine control over the individual branches and supply systems. It senses variation in loads, fluctuations in different generation and transmission lines (both voltage and frequency), and takes corrective action on its own to maintain system stability and supply quality .
