IntroductionFor the reasons of system restructuring and open transmission access, the regional power transfers vary over a wide range. Consequently, there are more and more power transactions are dealt via the transmission system. However, the capacity of system security is constrained by physical limits and reliability requirements [12]. Nonetheless, many concerning utilities of electric power devote multitude of effort and capital to enhance power system in a sufficient robust for surviving a cascading disturbance in a heavy demand, the interconnected network still suffer from widespread and lengthy blackouts [35].As well known as above lesson, the impacts of a power disturbance occurring in anywhere of the system, not only causes internal frequency of the system in perturbation but also possibly influence neighboring systems to be instable via tie lines [6]. In order to alleviate such a propagating disturbance from one system to another, this paper presents a possible solution to this problem by introducing an autonomous dispersed control conception on multiple ESFs to alleviate the shortterm disturbance for the enhancement of system stability [78]. However, a large number of system data and heavy putations are always needed for carrying out the above proposals. Moreover, such the patterns of central control are lack of flexibility for the extension from the local areas to interconnected system.

Imagination of ESF Control SystemIn this paper, the imagination of proposed conception is shown in . 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 as ACE resulting from a disturbance in a system. By the proposed control, ACE of each system can be subsided to be minimum and stabilize system oscillation. 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 interconnected system. In order to perform the particular interesting of proposed conception to the case in the loop networks, the WSCC threemachine ninebus system is taken as a study example to confirm the appropriateness and effectiveness of the control.II. Proposed Control SchemeThose roles such as ACE, tieline bias control (TBC), and speed governors as well as AGC which play in the proposed control are described as following: AGC Control [9]For supplementary control of interconnected system, at the fist observing the performance of speed control only.
