A novel sensorless current shaping (CS) control strategy is proposed to avail better power quality (PQ) of a dc grid–based wind power generation system (WPGS) used on a poultry farm by generating an appropriate reference current for space vector pulse width modulation (SVPWM) inverter. The proposed CS strategy also offers adequate control for parallel operation of multiple generators and inverter applications, without requiring voltage and frequency synchronization. Further, to control the poultry farm–based WPGS, a two‐stage control loop is implemented such as energy flow control loop (EFCL) and harmonic control loop (HCL). The first loop is used to regulate the power flow, and the second loop is used to compensate harmonics. A mathematical current decomposition technique is suggested for an appropriate resistance emulation to realize a better power flow, higher harmonic rejection, and better inverter operation. In this planned approach for attaining constant wind speed, an electric ventilation fan in the poultry farm is used. A combined hybrid dc and ac grid approaches are suggested for facilitating variable load integration in a poultry farm–based microgrid system. Moreover, for achieving better power management during the islanded mode of operation, the battery energy storage (BES) device is integrated with the dc grid through a bidirectional converter. The proposed WPGS design and control approach has been simulated through MATLAB/Simulink software under various test conditions, to demonstrate the operational capability, to achieve better PQ, and to increase the flexibility and reliability in the microgrid operation.

基于直流电网的风力发电系统中具有电压干扰抑制功能的SVPWM逆变器的新型无传感器电流整形控制方法

提出了一种新颖的无传感器电流整形（CS）控制策略，以通过为空间矢量脉冲宽度调制生成适当的参考电流，以在家禽场上使用基于直流网格的风力发电系统（WPGS）获得更好的电能质量（PQ）。 （SVPWM）逆变器。所提出的CS策略还可以为多个发电机和逆变器应用的并联运行提供足够的控制，而无需电压和频率同步。此外，为了控制基于家禽场的WPGS，实现了两级控制回路，例如能量流控制回路（EFCL）和谐波控制回路（HCL）。第一个回路用于调节功率流，第二个回路用于补偿谐波。建议使用数学电流分解技术来进行适当的电阻仿真，以实现更好的功率流，更高的谐波抑制和更好的逆变器操作。在此计划的方法中，为了获得恒定的风速，在家禽场中使用了电动通风风扇。建议将混合的直流和交流网格方法用于在基于家禽场的微电网系统中促进可变负载集成。此外，为了在孤岛操作模式期间实现更好的电源管理，电池能量存储（BES）设备通过双向转换器与dc电网集成在一起。拟议的WPGS设计和控制方法已通过MATLAB / Simulink软件在各种测试条件下进行了仿真，以证明其操作能力，以实现更好的PQ，
