An Implementation of On-Line SCOPF Algorithm

On-Line SCOPF 알고리즘의 적용에 관한 연구

As power systems tend to be operated more closely to their ultimate ratings. the role of SCOPF is changed and the importance for real-time security inhancement will be more increased in the new and competitive electricity market. This paper deals with the application of the SCOPF which make possible the On-Line application. The security margin of power system truly is changed according to the conditions or configuration of power system, therefore, the sensitivity factor related to the security is recalculated and the application should be updated in accordance with the state of power system. The proposed mechnism has been tested on modified Woolenberg 18-bus system and the results show more secure conditions against critical contingencies.
