“…To illustrate the operation of the proposed converter, The inductor in Input Converter (Ls) is an interface reactor which, likewise that of STATCOM, is added to reduce current ripples due to the switching [27][28][29]. In comparison with the other voltages, the inductor voltage is small, and, therefore, its effect is neglected in analysis of the converter.…”

“…Also, when the variation of wind speed is high, as a function of the output power, it causes fluctuations in the system voltage. Dynamic compensation means including: static synchronous series compensators (SSSC), unified power flow controllers (UPFC), unified power quality controllers (UPQC), static VAR compensators (SVC) and STATCOM [3,4] are therefore used in voltage regulation through the reactive power needed.…”

This paper examines the impact of a high penetration of Squirrel Cage Induction Generator wind turbines (SCIGs) on the voltage regulation and reactive power compensation on a grid. It shows that SCIGs slow down voltage restoration after a voltage drop and can lead to voltage and rotor speed instability. When the voltage is restored, SCIGs will absorb reactive power and, if the voltage does not return quickly enough, the generator accelerates and consumes larger amounts of reactive power. This situation is exacerbated if the wind turbine is connected to a weak power system.A static synchronous compensator (STATCOM), can be utilised to maintain the voltage profile and to overcome a transient disturbance after faults. However, existing STATCOMs utilise fixed gain PI controllers that are unable to respond when the system is under extreme conditions such as a three phase to ground fault, sudden wind speed changes, load fluctuations and weak grid support. Therefore, in this work, an artificial neural network (ANN) based self-tuning PI controller is proposed. Simulation studies were conducted to demonstrate the effectiveness of the proposed controller in maintaining the system stability under such conditions.

“…When converter a.c. output voltage (Vc) > transmission system voltage (Vs), STATCOM considered to be in capacitive mode and when Vs > Vc, STATCOM considered to be in inductive mode and in No -Load mode Vs=Vc. No reactive power exchange takes place [4]. STATCOM mainly comprise of step down transformer with leakage reactance, three phase GTO voltage source inverter and a dc capacitor voltage [14].…”
