Why does Korean power system plan to provide Bess?

Due to the wide range of BESS capabilities as mentioned above, Korean power system plans to provision BESS to relieve generation curtailment and to provide FR service in the short-term applications, and to maintain frequency stability by providing FFR service in a low-inertia system for the long-term applications.

Is South Korea a powerhouse in the energy storage system industry?

South Korea has set an ambitious goal to rise alongside the United States and China as one of the top three powerhouses in the global energy storage system (ESS) industry by 2036. The nation plans to capture 35% of the rapidly growing global ESS market, aiming to revitalize its currently stagnant domestic ESS industry.

How to overcome stability issues in Korea's power system?

Besides, considering the short-term state of the Korean power system, another stability issue may arise due to the delayed reinforcement of the shared network connecting large-scaled generation plants. Several countermeasures such as generator tripping and generation curtailment are proposed to overcome stability issues.

What is GCR-Bess capacity of Korean power system?

A historical data of Korean Power System when the occurrence of under frequency event is used to depict the performance of the proposed BESS control strategy. This simulation was applied using MATLAB/Simulink. The GCR-BESS capacity is assumed to be 112 MW/56 MWh.

What is an energy storage system (ESS)?

An ESS, or Energy Storage System, is a facility that stores excess electricity using large quantities of secondary batteries to use it later. As countries around the world push for carbon neutrality around 2050, there’s an increasing demand for renewable sources like solar and wind energy, as well as carbon-free energy (CFE) like nuclear power.

Does South Korea need ESS?

South Korea recognizes the growing need for ESS. According to the 10th Basic Plan for Power Supply and Demand confirmed earlier this year, the percentage of rigid power sources, which are difficult to adjust in terms of output, will increase from 34% in 2021 to 54.0% in 2030 and 65.2% by 2036.
