The integration of wind power generation (WPG) have many different impacts on the current power transmission and distribution systems. Most of them are related to their effect on the dynamic behaviour and frequency deviation during system frequency disturbances affecting the system inertia response. Different approaches have been presented to show the dynamic behaviour diminution, and several metrics have been proposed to quantify the impact of the inertia reduction. This scientific paper looks at the background system inertia problem, presenting some of the most significant contributions in observation of power system dynamic under high penetrations of WPG and presents two dynamic measurements. First one measures the damping ratio of the power lines quantifying it in an online fashion. The second one measures the frequency of an electrical power signal. The dynamic measurements are tested in a hypothetical active power signal with the inclusion of wind energy showing the affectivity of the dynamic measurements presented and the impact of wind farms in power systems. Finally, future work and conclusions are given.
