Summary:We numerically study the effects of the asymmetry of the transmission lines capabilities, of the transmission delay and power noises, on the stability of an elementary electricity network consisting of one machine and two generators. It is found that the asymmetry increases the stability of the system. It is also found that the threshold value of the perturbation intensity leading to the network instability decreases as the time delay increases. When the system is subject to a stochastic perturbation, its stability depends not only on the noises intensity, but also on the time delay and the value of the transmission lines capabilities.
