Island Microgrid Analysis

Are island microgrids a viable solution?

Island microgrid (IM) systems offer a promising solution; however, optimal planning considering diverse components and alternatives remains challenging. Using China's Yongxing Island as a case study, we propose a novel indicator system integrating economic, resilience, energy, and environmental dimensions.

What is an island microgrid (IM) system?

Through the use of an island microgrid (IM) system, local energy resources which islands are usually rich in, e.g., wind and solar, can be utilized more efficiently. Integrating local energy resources, not only reduces the cost of the IM system [ 8] but also enhances post-fault reliability for local consumers.

Which island hybrid microgrid is best?

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.

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.

How is a microgrid system designed?

The microgrid system is designed according to the HOMER and MATLAB optimized system architecture. This simulation is done to focus on the various power system uncertainty analysis of the microgrid model. In this analysis, it is observed whether the system performs properly or not. Also, the three-phase bus voltage, current, and power are observed.

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.
