IntroductionFor the reasons of system restructuring and open transmission access, the regional power transfers vary over a wide range. Consequent

Nonetheless, many concerning utilities of electric power devote multitude of effort and capital to enhanc

12、magination of ESF Control SystemIn this paper, the imagination of proposed conception is shown in Fig.1. Each tie line which connects with two systems is installed an ESF in its both terminals. The function of each ESF can be considered as a power buffer to absorb the flow deviation of the tie line

Furthermore, since the proposed control is only based on the local information of an area, it is possible to extend the control scale to an int
