Microgrids and the future of the power industry

Microgrids connect to the main grid through a Point of Common Coupling (PCC), which imports and exports electricity as needed. A micromanager sits at the centre and balances generation against load. Control systems within the microgrid are critical for monitoring demand and effectively matching supply. There are many different types of microgrids.

Networked microgrids is a cluster of local grids that can be connected through a weak network and can provide ancillary services. On a system point of view, it is desirable that every microgrid exhibits a behaviour at the Point of Common Coupling (PCC) which enables to share active and reactive powers with other grids.

Generation scheduling at PCC in grid connected microgrid

Reliability Assessment of Multi-Microgrids Considering

Microgrids (MG) that are located near each other may have varying levels of power supply redundancy. Therefore, interconnecting two or more microgrids into one multi-microgrid (MMG) system can lead to improved overall power supply economics and reliability. Multi-microgrid systems are often more complex than single microgrids. Reliability research is
