The integration of the wind generator into the grid connected system becomes a challenge. The major problem is to have a dynamic reactive power support along with the controlled real power support from the source. In this paper a control algorithm is proposed to maintain the unity power factor of the source supply with no reactive power support from the source. The static compensator ( STATCOM ) is connected at a point of common coupling (PCC) with a battery energy storage system (BESS).The STATCOM and energy storage is interfaced with wind generating system, supporting the real and reactive power and also maintain the stable voltage at PCC and support the grid. The effectiveness of the proposed scheme relieves the main supply source from the reactive power demand of the load and the induction generator. The reactive power compensation by STATCOM with bang-bang controller with hysteresis based technique maintains the dynamic stability of the grid and matches the operating behavior of grid system. This scheme is simulated with a MATLAB/SIMULINK in power system block set, having interface of induction generator and non-linear load at PCC and performance is evaluated.

Abstract The feasibility of integration of Battery Energy Storage System (BESS) with a three-phase AC grid is being investigated in this paper. A converter is an inevitable part of a modern DC generating system. The link between the grid and the BESS is established through a Voltage Source Converter (VSC). Therefore, the converter can be utilized to dispatch the DC generated power to the connected AC grid and at the same time provides reactive power compensation and load harmonic compensation throughout the day. The DC bus voltage control of the converter system is carried out to keep the power factor always at unity, irrespective of the charging state of the battery source. The charging and discharging of the connected battery energy storage system are carried out through a bidirectional DC-DC converter. Adaptive hysteresis band current control (AHCC) scheme is employed to produce the switching signals. Finally, its performance is compared with the traditional hysteresis band control technique.

In this paper, enhanced field oriented control technique (EFOC) was adopted in Rotor Side Control (RSC) of DFIG converter for improved response during severe faults. The work is intended to damp pulsations in electromagnetic torque, improve voltage mitigation and limit surge currents and to enhance the operation of DFIG during voltage sags. The converter topology uses a battery energy storage system with capacitor storage system to further enhance operation of DFIG during faults. The battery and capacitor system in coordination provide additional real and reactive power support during faults and nearly constant voltage profile at stator and rotor terminals and limit overcurrents. For EFOC technique, rotor flux reference changes its value from synchronous speed to zero during fault for injecting current at the rotor slip frequency. In this process DC-Offset component of flux is controlled, decomposition during overvoltage faults. The offset decomposition of flux will be oscillatory in a conventional FOC, whereas in EFOC it will damp quickly. A comparison is made with proposed methodology with battery energy storage system and a conventional system. Later the system performance with under voltage of 50% the rated voltage with fault at PCC during 0.8 to 1.2 seconds is analysed using simulation studies.

With the growing application of green energy, the importance of effectively handling the volatile nature of these energy sources is also growing in order to ensure economic and operational viability. Accordingly, the main contribution of this work is to evaluate the revenue potential for wind parks with integrated storage systems in the day-ahead electricity markets using genetic algorithm. It is achieved by the concept of flexible charging–discharging of the Energy Storage System (ESS), taking advantage of the widespread electricity prices that are predicted using a feedforward-neural-network-based forecasting algorithm. In addition, the reactive power restrictions posed by grid code that are to be followed by the wind park are also considered as one of the constraints. Moreover, the profit obtained with a Battery Energy Storage System (BESS) is compared with that of a Thermal Energy Storage System (TESS). The proposed method gave more profitable results when utilizing BESS for energy arbitrage in day-ahead electricity markets than with TESS. Moreover, the availability of ESS at wind park has reduced the wind power curtailment.
