Output Power Smoothing Control for the PMSG Based Wind Farm by Using the Allocation of the Wind Turbines

This paper proposes an output power smoothing control strategy for the wind farm without any other energy storage devices (ESS), which is based on the allocation and control of the wind turbines (WT). The wind turbines in the wind farm are divided into control wind turbines (CWT) and power wind turbines (PWT) separately while playing different roles. The PWTs are expected to output as much power as possible by giving the maximum power point tracking (MPPT) control strategies. The CWTs are in charge of the output power smoothing for the wind farm by giving the appropriate power. The model of the direct-drive permanent magnet synchronous generator (PMSG) based wind farm is built based on Matlab/Simulink and the efficiency of the proposed power smoothing control strategy is verified by the simulation results.
