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.
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.
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.
Key technologies such as control technology and energy management for island microgrids are studied. Renewable energy penetration is discussed for the design and operation of island microgrids. The operation data for a year of the three island microgrids are analyzed from various aspects.
The Isle of Eigg microgrid project is built on an island located off the Scotland Coast , which includes 110 kW of hydro power, 24 kW of wind turbine (WT), and 32 kW of PV. A model of Eigg is created using HOMER software and assessed to ensure that it was a valid representation of the electrical network present on the island.
The proposed optimized island hybrid microgrid is referred to as the best in terms of system availability and reliability, because it addresses three crucial criteria: techno-economic feasibility, system dependability and system availability to ensure a continuous power supply for remote and island areas of Bangladesh, such as Bhansan Char.
