Remote Microgrids in South Korea
Gasa Island, located at the southern part of South Korea, is
a typical remote microgrid that can be run in fully off-grid
operation modes. This remote island is equipped with die-
sel generators and Li-Ion-based ESSs with grid-forming
inverters as the interfaces and DERs (i.e., PVs and wind
turbines). The technical specifications are listed in Table 2.
Because sufficient power is provided by diesel generators
and ESSs, the penetration level of RESs can be adjusted
with flexibility.

Conclusions
With the increasing needs of electrifying remote commu-
nities with acceptable reliability and resilience expecta-
tion, remote microgrids have been widely deployed, and
the corresponding technologies have been extensively
studied in the past years. Existing planning issues are
driving technology advances in remote microgrids to
achieve optimal and cost-effective design as well as meet
the performance requirements defined by users. Mean-
while, stability enhancement also plays a significant role
in the operation of remote microgrids. Different types of
software tools are available to assist in the design and
assessment of remote microgrids, whereas their func-
tionalities are still being improved to meet the require-
ments in terms of both planning and operation. Pilot
projects of remote microgrids can be found all over the
world, which illustrates the significance and impact of
related technologies.
