“…The smoothing methods are classified into two groups; (i) without utilization of energy storage devices and (ii) by utilizing energy storage devices [24,25]. The first group is based on pitch angle control [37] and the kinetic energy of inertia control [38]. These approaches require low expenditure and often fail to catch the maximum available wind power.…”

Abstract:Wind energy is one of the most common types of renewable energy resource. Due to its sustainability and environmental benefits, it is an emerging source for electric power generation. Rapid and random changes of wind speed makes it an irregular and inconsistent power source when connected to the grid, causing different technical problems in protection, power quality and generation dispatch control. Due to these problems, effective intermittent smoothing approaches for wind power output are crucially needed to minimize such problems. This paper reviews various intermittent smoothing approaches used in smoothing the output power fluctuations caused by wind energy. Problems associated with the inclusion of wind energy resources to grid are also briefly reviewed. From this review, it has been found that battery energy storage system is the most suitable and effective smoothing approach, provided that an effective control strategy is available for optimal utilization of battery energy system. This paper further demonstrates different control strategies built for battery energy storage system to obtain the smooth output wind power.

“…The rest of Protor is stored as rotational kinetic energy. It can be regulated by controlling the rotor speed r  and angular acceleration of the rotor r   in coordination to reduce the fluctuation of Pe [26,27]. Thus Protor supplies the capability to balance efficiency and power smoothing.…”

Abstract:In wind turbine control, maximum power point tracking (MPPT) control is the main control mode for partial-load regimes. Efficiency potentiation of energy conversion and power smoothing are both two important control objectives in partial-load regime. However, on the one hand, low power fluctuation signifies inefficiency of energy conversion. On the other hand, enhancing efficiency may increase output power fluctuation as well. Thus the two objectives are contradictory and difficult to balance. This paper proposes a flexible MPPT control framework to improve the performance of both conversion efficiency and power smoothing, by adaptively compensating the torque reference value. The compensation was determined by a proposed model predictive control (MPC) method with dynamic weights in the cost function, which improved control performance. The computational burden of the MPC solver was reduced by transforming the cost function representation. Theoretical analysis proved the good stability and robustness. Simulation results showed that the proposed method not only kept efficiency at a high level, but also reduced power fluctuations as much as possible. Therefore, the proposed method could improve wind farm profits and power grid reliability.

This paper details the study of permanent magnet synchronous generator (PMSG) for wind turbines and its control for maximum power point tracking, while connected to a High Voltage Direct Current (HVDC) bus using a 12 pulse thyristor network. The connection to the HVDC bus is done without the use of a back-to-back converter for the PMSG, reducing the complexity and cost of the PMSG power converter. The use of SCR (Silicon Controlled Rectifier) vs IGBT at higher power levels also offer lower cost. HVDC power distribution allows ease of integrating DC storage for power conditioning and support the stability of the utility grid. Proposed new Wind Energy Conversion Systems (WECS) is described in details and is verified by using MATLAB software and hardware setup.
