Island Microgrid System Design Paper

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.

Do inverter-based Island microgrids have grid-forming capabilities?

Similar to a conventional power grid with synchronous generators, the grid-forming capabilities in an inverter-based island microgrid are provided by grid-forming inverters [114, 115]. Fig. 4 represents the inverter-based MG schematic.

What is a microgrid?

In recent years, the term microgrids (MGs) has been used in the electric power community [7, 8]. A MG is a low-voltage electrical grid that is autonomously operated from a larger primary grid [9, 10].

Why is microgrid research important?

Research on the use of microgrids has attracted the attention of researchers because it plays an important role in the success of microgrid operations. Microgrid (MG) can improve the quality, reliability, stability and security of conventional distribution systems.

What are the environmental performance of a microgrid?

The environmental performances of the microgrid are measured by the emissions of carbon dioxide, sulfur dioxide, and nitrogen oxide [ 49 ]. It is noted that a sustainable energy system is desired to have a lower value of all the six indicators, as specified by Eqs. (7), (8), (9), (10) ).
