DER-based hybrid microgrids are the future of power systems.

Should MV grid be strengthened in the Gambia?

Reinforcement of the MV grid from Farafenni or via a cable across the river from Banjul are alternatives that may be considered if the western corridor does not present a viable solution. Transmission developments in The Gambia should be considered in relation to regional options.

Why do Hybrid microgrids cost more than traditional grids?

1. Cost—As hybrid microgrid is a new concept, many features of traditional grids such as three-phase balanced conditions, inductive transmission lines, and constant power loads do not exist for microgrids; therefore, these models need to be redesigned for compatibility, so initial cost increases. 2.

What are the limitations of a hybrid microgrid?
