The output of the PMSG based wind energy conversion system (WECS) is fluctuating in nature due to intermittency of wind speed. The distribution static synchronous compensator (DSTATCOM) incorporated with the battery energy storage system (BESS) is used to smooth the power produced from wind generator system. The control strategy of BESS/DSTATCOM and its integration to mitigate the power fluctuations of grid connected WECS is presented. Three-leg three-phase voltage source converter (VSC) based DSTATCOM is used and the battery current is controlled to smooth the net power injected to the utility grid from wind power generation system. The control strategy implemented has the capability of supplying the required amount of power to the utility with help of batteries. The PQ control strategy is employed to control the three-phase inverter for managing power exchange with the utility grid. The real time wind speed data is considered for the simulation study of the system. The effectiveness of the control strategy of the system is validated through the simulation results in MATLAB/Simulink environment.

摘要——由于风速的间歇性， 基于 PMSG 的风能转换系统（WECS） 的输出具有波动性。 将配电网静态同步补偿器（DSTATCOM） 与蓄电池储能系统（BESS） 相结合， 用于平滑风力发电系统产生的功率。 本文提出了 BESS/DSTATCOM 及其集成控制策略，以减轻并网 WECS 的功率波动。 采用基于 DSTATCOM 的三桥臂三相电压源型变流器（VSC）， 通过控制蓄电池电流来平滑风力发电系统注入电网的净功率。 所实施的控制策略具有在蓄电池的帮助下向公用电网提供所需电能的能力。 采用 PQ 控制策略对三相逆变器进行控制， 实现对与电网进行功率交换的管理。 系统的仿真采用了实时的风速数据。 在 MATLAB/Simulink 环境下， 仿真结果验证了该系统控制策略的有效性。 可用作参考文献、毕设外文翻译。
