| Abstract |
In case of 765kV transmission line tripping, there is a Special Protection Sheme(SPS) in Korea power system. To avoid generator over-speed, preselected generators can be tripped by SPS. However, the system frequency can be under the Under Frequency Relay(UFR) 1st pickup level 59.92Hz when large scale generators are tripped. Accordingly, generation constraints can arise until new transmission lines are installed. In this paper, we proposed BESS for mitigating generation constraints of large scale generators, and we applied to the Korean power system in 2022 to analyze the effects of BESS application. |
