“…In view of the battery has a high energy density but a low power density, the use of other energy storage elements with high power density could complement the battery to sustain the high power needed for relatively short durations [4]. The energy storage element could be a flywheel or a super capacitor, they are also used in many fields including Solar photovoltaic (PV) [5] and wind energy systems [6,7]. To manage the intermittency produced by the wind turbine generator, super capacitor is used as energy storage or combined with the battery into the hybrid energy storage system (HESS) for a doubly fed induction generator (DFIG) [8,9].…”

“…In [18,19] SC is used with power electronic converter to absorb the excess energy of wind energy system equipped with synchronous generator and full converter during the fault condition. 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.…”

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.

“…Hence, Flywheel control using Flux magnitude and angle control for power and voltage stabilization has been used [15] and for wind power smoothing such as the effects of wind fluctuations on system voltage and frequency, a hybrid energy storage system including a super capacitor and a flow battery is presented in a DFIG-based WT [16]. In addition, ESS and DC chopper circuit regulate generator output power in the grid-side converter and DC-link for improving FRT capability [17].…”

The paper presents dynamic and transient behavior of the doubly fed induction generator (DFIG) in the wind farms in the normal and faulted grid respectively. When Voltage sag or any fault occurs in the network, the variables in the Doubly Fed Induction Generators are varying severely. If a voltage sag occurs, active and reactive power generated by the DFIG start to oscillate. The DC-link voltage will be bigger and will have fluctuation, and the rotor current will increase. In this paper, proportional integral (PI) controllers are used to control the DFIG in the wind farms for driving of the electronic devices including Rotor Side Converter (RSC) and Grid Side Converter (GSC) and controlling the active and reactive power of DFIG. PI parameters are tuned by particle swarm optimization algorithm (PSO). Whereas the model of DFIGs and electronic device in the paper are nonlinear so PI controllers cannot protect and control the DFIG as well. Hence, effect of PI parameters is investigated on the DFIG with simulating in MATLAB software. Also, low voltage ride through (LVRT) feature for DFIG is explored in presence of PI controllers. The results of the simulation present DClink over voltage and rotor and stator over current in the DFIG. In addition, it will explore the effect of proportional integral controllers when three-phase short circuit fault occurs.
