What are the island microgrids?

Table 1. Summary of the island microgrids. Recently, three unique stand-alone microgrid projects have been built at Dongfushan Island, Nanji Island, and Beiji Island in the east China, with an aim to replace diesel with renewable energy to improve renewable energy utilization, enhance power supply reliability, and reduce power supply cost.

What are the benefits of a hybrid Island microgrid system?

One of the benefits of a hybrid island microgrid system is that it does not depend on national and/or central grids, which reduces a massive amount of power distribution costs . However, hybrid microgrid systems for isolated and/or remote locations still face many critical challenges.

How much does the island microgrid system cost?

Total economic easement of the island microgrid system is illustrated in Table 5, which concentrates on the cost-effective economic assessment of the microgrid system. The total NPC of the system is around 50,30,362 $, which is calculated from HOMER optimization. The optimized operating cost is around 86,090 $/yr.
