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.

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.

Are battery energy storage systems a countermeasure?

Using their fast response characteristic, battery energy storage systems (BESS) are regarded as a countermeasure to relieve the curtailment.

Why is South Korea implementing a Bess frequency regulation project?

South Korea is in the midst of the world’s largest BESS frequency regulation project. The target is to install 500MW by 2017. In addition to enhancing the efficiency of the grid, installing BESS capacity will reduce KEPCO’s need for readily available spinning reserve capacity.

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.
