    Abstract

    As the electric power demand increases, power systems have become larger and more complex. The dependence on the electric power in society tends to increase such as information products prevail. On the other hand, recently studies on applications of Global Positioning System (GPS) to power systems monitoring are being conducted. In this paper, at first we propose a GPS placement method with a viewpoint of effectively monitoring the power system stability. This method uses the first order eigenvalue sensitivities for phase angles from relationship between eigenvalues and phase angles. Next, we propose a method for determining more appropriate generation dispatch rescheduling to improve the power system stability when the power system stability deceases. At that time we use first and second order eigenvalue sensitivities. The proposed method is demonstrated using a sample 4 machine 10 bus system and we examine effectiveness of the second order eigenvalue sensitivities compared with the first order ones.
