Reliability assessment of island multi‐energy microgrids

AbstractMulti‐energy microgrids could result in more flexibility and increase reliability by interconnecting networks. Electricity and gas networks exhibit very different dynamic behaviours in response to a fault or failure. Gas networks have built‐in energy storages that can continue to provide a reliable supply if gas inputs to the system are compromised.

Microgrid

Microgrid. A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. [1] It is able to operate in grid-connected and in island mode. [2] [3] A '' stand-alone microgrid '' or '' isolated microgrid '' only operates off-the-grid and cannot be connected to a wider electric power system. [4]
