The Timor system is one of the large systems in the East Nusa Tenggara region. Based on the general plan for electricity supply for 2021-2030, there is a plan to interconnect a 2x11 MW wind power plant. The addition of wind power plants will pose a considerable threat to the system due to the intermittency nature of renewable energy plants. Therefore, a comprehensive grid impact study is needed to convince network managers that adding wind farms will not cause disruptions to the system either locally or in general and is expected to strengthen the electricity system. The power flow simulation results, installing a 2x11 MW wind farm on the Timor system can improve voltage quality and reduce losses on both 70 and 150 kV systems. For transient stability, the frequency value on the Timor system still meets the grid code requirements. In addition, the simulation results of the intermittency impact of the wind power plant output show that the Timor system is still in a stable condition. The stability of the rotor angle of the existing power plant when the transient stability simulation is carried out shows that it is still in a balanced condition.

“…As a method to decompose the solution into multiple time scales and to improve the calculation accuracy, the multiscale method has been continuously developed and applied in various disciplines. Moradi et al 18 carried out multiscale analysis on the single-degree-of-freedom meshing gear model, analyzed the stability and jump phenomenon of the system through the primary resonance, super-harmonic, sub-harmonic, and other aspects; Balaji et al 19 proposed a new structural dynamic model of bolt, which determines the local change of roughness parameters and predicts the influence process of local traction force on the system through multi-scale; Jokar et al 20 and Alper et al 21 explored the influence of various factors on system vibration through super-harmonic and sub harmonic; Wang et al 22 studied the influence of slip ratio, crack degree, damping ratio, static load and dynamic load on system resonance and stability by adding gear clearance, static transmission error, crack and other factors; Yu et al 23 established a dynamic gears model of nonlinear shearer, considering crack faults and multifrequency excitation, the amplitude-frequency characteristics of the primary resonance of the model were analyzed by the multi-scale method, the vibration and response of the system were calculated by the incremental harmonic balance method; Many authors [24][25][26][27][28][29][30] established nonlinear system model, through the multi-scale analysis, analyzing the stable region and unstable region of the system.…”

To study the nonlinear dynamic characteristics of the electric drive transmission system of clean propulsion vehicles, a rotor-bearing system consisting of dual-stage meshing gear pairs and multiple loaded bearings was established. The influence of time-varying meshing stiffness, tooth side clearance, bearing clearance, and other factors were considered. A multi-degree of freedom vibration differential of the system was established equation, to analyze the vibration characteristics of various parts of the transmission system under different parameters. Using time-domain diagrams, poincaré cross-sections, bifurcation diagrams, and other images to study the vibration of gears. In addition, the primary resonance stability equation of the system is derived and its stability under different conditions is analyzed using meshing damping, stiffness, and load as variables. The results show that as the rotational speed increases, the first stage gear of the system undergoes the “single cycle-bifurcation-chaos-bifurcation-single cycle” vibration process, while the second stage gear undergoes two such processes. The instability intervals can be obtained as [3092,4859] and [8098,10896] r/min, [2797,3533] and [9423,14135] r/min respectively. Avoiding these speed ranges helps to improve the stability and safety of automotive motion.
