Northeast Asia Power Interconnection Studies; Trends and Prospects in South Korea

Study on application of a high-speed trigger-type SFCL (TSFCL) for interconnection of power systems with different reliabilities

“…To overcome the shortage of power generation and improve the reliability of the power supply, the interconnection of multiple power systems has been carried out as a compromise [1][2][3][4]. The interconnection between power systems with differing electricity prices also provides economic benefits.…”

“…The interconnection between power systems with differing electricity prices also provides economic benefits. For example, the interconnecting grids between North and South Korea are expected to improve the reliability of the power supply and deliver economic advantages [4]. However, the differing reliability of the two power systems destabilizes the power system with greater reliability and reduces the power quality of the system, which is resulted from the voltage sags and fault currents through the tie line [5][6][7][8].…”

Development of Northeast Asia Interconnected Power Grid and Algorithm Assuring Reliability

“…Of course, the other nations secure more capacity to supply electrical power to customers and have several advantages more. Finally, we will deal with the algorithm based on NAIPG [6][7][8][9][10][11][12].…”
