“…The proposed RWEMA controller dynamically obtains the results from MWF and the SOC from the EDLC and NB bank, and then determines the reference value for the corresponding DC/AC inverter controller of HESS. Furthermore, the SOC control strategies are added to maintain the SOC levels of storage within their safe operating limits, which are normally between 20% and 80% for battery [14] and between 30% and 90% for EDLC.…”

“…Since both short-term and long-term wind power fluctuations cause severe negative effects on power system quality, stability, and reliability, they should be restricted within a certain limit, especially at a high wind power penetration level [14]. Several different RRLs have been proposed, depending on the recent situation of wind power of each country or the policies of power utilities.…”

“…Furthermore, they failed to neither ensure the system power output always satisfies ramp rate requirements nor consider to safe working limits of EESS. Jiang et al [14] implemented a wavelet-based capacity configuration and coordinated control algorithm for reducing output power fluctuations of a wind system using a lithium-ion battery-ultra-capacitor energy storage system. Although this paper proposed a novel approach for solving most of the above problems, it still used two stages of wavelet filtering that increase the computational complexity and require wind data prediction algorithm.…”

Abstract:Since the penetration level of wind energy is continuously increasing, the negative impact caused by the fluctuation of wind power output needs to be carefully managed. This paper proposes a novel real-time coordinated control algorithm based on a wavelet transform to mitigate both short-term and long-term fluctuations by using a hybrid energy storage system (HESS). The short-term fluctuation is eliminated by using an electric double-layer capacitor (EDLC), while the wind-HESS system output is kept constant during each 10-min period by a Ni-MH battery (NB). State-of-charge (SOC) control strategies for both EDLC and NB are proposed to maintain the SOC level of storage within safe operating limits. A ramp rate limitation (RRL) requirement is also considered in the proposed algorithm. The effectiveness of the proposed algorithm has been tested by using real time simulation. The simulation model of the wind-HESS system is developed in the real-time digital simulator (RTDS)/RSCAD environment. The proposed algorithm is also implemented as a user defined model of the RSCAD. The simulation results demonstrate that the HESS with the proposed control algorithm can indeed assist in dealing with the variation of wind power generation. Moreover, the proposed method OPEN ACCESSEnergies 2014, 7 6621 shows better performance in smoothing out the fluctuation and managing the SOC of battery and EDLC than the simple moving average (SMA) based method.

“…At this time, if the wind turbine is not involved in the system frequency regulation, the equivalent power generation capacity and the inertia of the rotor are reduced, which causes the faster reduce or increase the system frequency [1]. In addition, the frequency of the system may also be difficult to recover to normal levels after the disturbance disappeared [2][3]. At present, the double fed wind induction generator (DFIG) is used for system frequency modulation.…”

Keywords:The frequency and voltage coordinated control, wind/storage system, real time digital simulation (RTDS). Abstract: Due to the characteristics of the operation of the wind turbine and the capacity of the converter and the rotor current and other factors, the use of wind turbine to adjust the system frequency and voltage can not fully meet the requirements. And energy storage equipment has the advantages of flexible and controllable. In the paper, the frequency and voltage coordinated control for wind power and energy storage system is studied. And its coordinated control strategy is proposed. Three kinds of control scheme comparison are considered in the simulation to verify the validity of the control strategy proposed. The simulation results show that the control strategy is effective and easy to apply engineering practice.

Summary The variations of wind generation result in the considerable fluctuations of the system frequency, which are difficult to be regulated in the acceptable range in electric power systems with highly penetrated wind generations. This paper suggests an enhanced frequency control scheme with dynamic droop coefficients of a doubly fed induction generator (DFIGs, type 3) that is able to mitigate the fluctuations of the system frequency with more efficiency. To this end, a supplementary control loop with system frequency‐dependent droop control coefficients is employed based on the deviation of the system frequency. Simulation results clearly indicate that the suggested frequency control scheme is benefit to improving the frequency regulation capability under various wind speed patterns and penetration levels as energy storage systems do for frequency regulation, particular in highly wind generation penetrated power systems.
