“…Constant power control is provided by using the supercapacitor model in DFIGs. Moreover, a management control unit has been developed to provide power tracking [2][3][4][5]. Supercapacitors are used in DFIGs to obtain constant output power as well as to prevent frequency changes of switching elements in the converter circuit.…”

The supercapacitor is among the elements commonly used to store energy as an important component in sustainable energy systems. In doubly fed induction generators (DFIGs), the supercapacitor is used to compensate voltage dips and damping oscillations. In this study, a different supercapacitor model was developed for system stability in a DFIG-based wind turbine connected to an infinite bus. In the development of the mathematical supercapacitor model, the lookup table was realized with the voltage-capacity relationship and sliding mode control. DFIG modeling with/without the developed supercapacitor was performed for symmetrical and asymmetrical fault situations, and the findings were then compared and interpreted in detail. The simulation study analysis was conducted in a MATLAB/SIMULINK environment. The developed supercapacitor model yielded impressive results in symmetrical and asymmetrical faults.

“…In [20][21][22][23][24][25] SC is used to improve LVRT of wind energy system equipped with DFIG and back-to-back converter during the fault condition. However, in [8,[26][27][28], SC is used to achieve constant output power during wind speed variation. SC combined with the crowbar is used in [21] to protect the converter and improve (LVRT) capability of DFIG during grid faults.…”

This paper proposes constant active and reactive power control of a wind farm during gust using the supercapacitor (SC) and static synchronous compensator (STATCOM). The proposed technique is applied to Gabal El-Zayt wind farm which located in Red Sea region of Egypt with a capacity of 200 MW and equipped with doubly fed induction generators (DFIGs) and analyzed during gust wind. As the nature of wind is varying all time, the output power is changing continuously so energy storage system such as SC is required. SC is responsible for maintaining constant output active power by charging when there is excess in the output power of DFIG and discharging when there is a lack in the output power of DFIG. Reactive power compensation is achieved by connecting STATCOM to the power system. SC keeps reactive power constant however its value is improved by connecting STATCOM. Wind farm model is analyzed during gust with the proposed technique while active and reactive power performance is investigated. Firstly, the effect of connecting SC to each wind turbine is studied. Then the effect of connecting STATCOM to the electric power system is studied. Also, the effect of connecting SCs and STATCOM is studied. Finally, the impact of connecting additional STATCOM at different locations is investigated. Results show the proposed technique validity.
