“…The strategies used in [5,28,29,31,45,57,70] operate the WT at the sub-optimal power curve instead of MPPT control to improve the power reserve margin for frequency regulation, which unavoidably limits the power extraction capabilities of WTs in the normal operation. Some researchers [5,29,31,70] proposed schemes to co-ordinately control the charging/ discharging of KE and pitch angle. They formulated optimisation models to minimise the power waste amounts and maximise the KE storage within the WTs.…”

“…As is known, once the rotor speed control is adopted, the affected power acquisition coefficient inevitably leads to energy waste compared with the MPPT algorithm. Some scholars in [64,70] formulated the contradiction between energy waste and smoothing performance as an optimisation issue. Jin Lin in [83] used the binary search method to trade-off power levelling performance and energy loss.…”

Variable-speed operation of wind turbines (WTs) achieved through electronic converters can decouple wind generator dynamics from power systems. Besides, the wide rotor operation range makes it possible for the WT to tap the potential of kinetic energy (KE) in the rotating mass. This study provides an overview of utilising KE from WTs for grid connections. The availability of KE in WTs is acquired by the rotor speed alternation, both in static and dynamic processes. For the static state, the rotors of WTs operate at a pre-defined power curve which leaves the generation margin for KE release; while for the dynamic process, the KE is passively changed by the imbalance between mechanical and electrical power. Some emerging technologies in frequency regulation and low-voltage ride through capability with the participation of KE stored in WTs are investigated. The applications of KE in terms of wind smoothing are summarised as well. Finally, this literature review also discusses some potential future applications of KE management.

“…The direct power control usually depends on using the wind turbine (WT) itself without energy storage devices, such as through the DC bus voltage control, rotor inertia control, and the pitch angle control [3,[6][7][8][9][10][11]. However, the DC bus voltage control may cause the excessive voltage ripple, thus affecting normal operation of the WECS [5].…”

Output Power Smoothing Control for a Wind Farm Based on the Allocation of Wind Turbines

et al. 2018

This paper presents a new output power smoothing control strategy for a wind farm based on the allocation of wind turbines. The wind turbines in the wind farm are divided into control wind turbines (CWT) and power wind turbines (PWT), separately. The PWTs are expected to output as much power as possible and a maximum power point tracking (MPPT) control strategy combining the rotor inertia based power smoothing method is adopted. The CWTs are in charge of the output power smoothing for the whole wind farm by giving the calculated appropriate power. The battery energy storage system (BESS) with small capacity is installed to be the support and its charge and discharge times are greatly reduced comparing with the traditional ESSs based power smoothing strategies. The simulation model of the permanent magnet synchronous generators (PMSG) based wind farm by considering the wake effect is built in Matlab/Simulink to test the proposed power smoothing method. Three different working modes of the wind farm are given in the simulation and the simulation results verify the effectiveness of the proposed power smoothing control strategy.
