“…Hence, this section presents the results of the methodology applied to the equivalent of the Mexican power system, in the area of the Istmo of Tehuantepec, Oaxaca, Mexico, where there is a high penetration of wind power plants. Figure 9 shows the system presented in [38]; the system is composed of 24 wind power plants with the doubly-fed induction generator technology, and they are distributed in Ixtepec (14 wind power plants, 1438 MW) and Juchitán (10 wind power plants, 782.75 MW), with a total installed capacity of 2220.75 MW [39]. Two case studies were carried out in the professional software DIgSILENT PowerFactory.…”

High penetration of wind power plants may have an adverse impact on power systems’ stability by reducing the inertia, and problems like frequency stability could appear due to total inertia in the system being reduced, making the power system more vulnerable to disturbances. However, most recent grid codes include an emulation inertia requirement for wind power plants, because modern wind turbines are capable of providing virtual inertia through power electronic converter controls to improve frequency stability issues. Because of this, it is necessary that the inertia estimation analyze and quantify the impact of the inertia reduction in power systems. In this paper, an implementation of a methodology for the inertia estimation of wind power plants is presented. It is evaluated through synchrophasor measurements obtained from a Real-Time Digital Simulator (RTDS) implementation, using industrial Phasor Measurement Units (PMUs). This methodology is based on the swing equation. Furthermore, a comparison of the results obtained between two professional tools RSCAD and DIgSILENT PowerFactory is performed, in order to evaluate the accuracy and the robustness of the methodology. This methodology is applied for the inertia estimation of an equivalent of the southeast zone of the Mexican power system, where there is a large-scale penetration of wind power plants. The results demonstrate that this methodology can be applied in real power systems using PMUs.

Assessment of frequency performance by wind integration in a large‐scale power system

Large‐scale grid integration of wind energy particularly in the southeastern portion of the Mexican interconnected power system has affected available transfer capability and imposed additional uncertainty on power system operation. Integrating large amounts of wind energy into the system is challenging because of the variability in power system dynamics and a more complex active and reactive power dispatch. Wind plants have been installed in the Mexican systems during the past few years. The total installed wind energy capacity of the system is around 2.5 GW; the total wind energy generation represents 4% of current installed generation in the Mexican system. Increase of the wind power is expected to have an impact on power system control and transient behavior, especially as the amount of wind generation represents a significant portion of the local generation and wind farms grow in size and complexity. Using recent planning and operation wind data, detailed studies on the effects of new wind generation on power system dynamic behavior are carried out. Analyses of the dynamic impact of large wind parks on power system dynamic performance are conducted. Operating impact studies include frequency behavior and the response of wind farms to major disturbances. Simulation studies on a realistic 4000‐bus dynamic model of the Mexican interconnected system show that large wind generating plants have a significant effect on system dynamic behavior.
