Does Korea have a microgrid?

Korea's microgrid has been expanding since 2009 to meet needs such as output stabilization, peak reduction, and demand response for renewable energy sources such as solar power, wind power, and others. The number of MG and ESS installations nationwide has grown to 1,267 sites with 4.3 GWh of total storage.

What is Korea's first microgrid?

In 2011, we developed the energy-independent microgrid in Jeju-do, Gapdo, representing the first commercialized microgrid in Korea. In 2013, the central power grid was connected to the KEPCO (Korea Electric Power Corporation) Guri Branch office building, and the city of Seoul expanded apartment veranda installations of solar minigrids.

What is the current microgrid policy in the ROK?

The current microgrid policy in the ROK has been focused on expanding renewable energy use for electricity generation. Reinforcement of the national transmission and distribution system is necessary because a rapid increase in the amount of intermittent renewable energy inputs can lead to instability in the central grid.

What are energy storage systems in Korea?

Energy Storage Systems consist of lithium-ion or lithium phosphate batteries, power control systems, and operating software (Figure 1). There are three types of Micro grids in Korea, as described below. In Korea, three types of microgrids are used: self-sufficient, islanded, and connected to the central grid.

Does KEPCO have a microgrid?

In 2015, the KEPCO Human Resources Development Center installed microgrids for nine buildings and is operating those microgrids in connection with the central power grid.

What are government-led smart grid projects?

Large-scale government-led smart grid projects have been underway since 2009 at the Jeju Test Bed, with the goals of verifying microgrid technology grid stabilization, demonstration of economic feasibility, and development of business models for commercialization.
