Linear optimal control of one-machine infinite-bus model & consideration of order increase of machine model

Network optimization is one of the main ways to reduce the cost of the system and in most cases to improve its stability. LOC is a general stabilizing technique for power electric systems. In fact, this technique is applicable to multi machine, with multimode, high and low-frequency oscillations; although this paper only addresses linear and reduced machine-order equations which are derived from an equivalent system with an infinite-bus and a line. This paper first studies the influence of optimization on a system of one- machine infinite-bus with a line as connector. Then we study the effect of machine order increase in the response of the system.
