Transient Stability Study of Power System with Large-Scale Wind Farm Integration

Abstract

Large-scale wind power integration has become the current development trend of the power system. Large-scale wind power integration can change the original structure and characteristics of the system. Thus, it's necessary to analyse the transient stability of power system which contains wind power, and to study the controlling strategy for improving the transient stability of power system. Based on EEAC, this paper studies the transient stability of the power system which contains wind power system theoretically, proposes the calculation method for accelerating area, decelerating area and margin, and illustrates the impact of wind power integration on the transient stability with power angle curve. Furthermore, this paper studies the modeling and simulation, and the experimental results prove the correctness of the theories.

Analysis of the influence of high voltage ride-through characteristics on transient stability of wind turbines

“…For static reactive power generators, the role of capacitance and inductance is to provide voltage and power supply for inverter grid-connected, but in comparison, most of the voltage source type SVG is more, the current source type of energy storage element loss degree is more serious than the voltage source type, long-term use will be because of the loss of the DC side caused by the energy interaction can not reach a larger threshold, on the other hand, the current type must use bidirectional voltage blocking ability of high-power full control devices, the same inductor in overvoltage is relatively poor with capacitance, It is necessary to add a relevant voltage protection circuit on the DC side of the current source type [10] .…”

Application of Hilbert Spectrum based on SWT to Low-Frequency Oscillation Analysis

“…The range of LFO frequency is around 0.2 Hz to 3 Hz. It is the LFO issue that seriously affects power systems' safety and stable operation [2].…”
