Effect of Levy Type Load Fluctuations on the Stability of Single Machine Infinite Bus Power Systems
(IEEE, 2017) Yılmaz, Serpil; Savacı, Ferit Acar
In this paper, the stochastic excitations in single machine infinite bus power systems have been modeled as alpha-stable Levy processes. Through the simulations of the corresponding stochastic differential equations, we have shown that the impulsiveness and/or asymmetry in the distributions of the load fluctuations can cause the instability of the rotor angle. Hence, the synchronism is lost and the rotor angle although it is stable in the sense of probability, it might not be stable in the mean square sense. However, by properly choosing the parameters of Levy type fluctuations the rotor angle stability can be improved in the sense of probability as the beneficience of noise.
Analog Realization of the Quantum Derivative Operator
(IEEE, 2017) Savacı, Ferit Acar; Erdoğan, R. Uğraş
In this paper, quantum derivative operator which is basic to quantum calculus has been implemented as an analog circuit. The proposed circuit realization and the simulations have been also compared with that of the quantum derivative operator implemented in Mathematica.
