The proposed system comprises of the hybrid (PV and wind) system for 1 kw is integrated with the single phase grid. The new control scheme sine pulse width modulation (SPWM) switching with a deadbeat based PI controller is designed to a DC/AC single phase inverter. This controller is used to pure sinusoidal output voltage with low total harmonic distortion (THD), fast dynamic response control techniques and to keep the power output constant if any variation in the input from the PV and wind system occurs, and the output voltage at the grid remains constant. Even when the load varies, the sinusoidal voltage output maintains 230Vrms with 50 Hz frequency and also low THD is 2.54%. This controller proves the stiffness and robustness characteristics for maintaining the output voltage at desired value with low harmonics.

光伏和风电混合系统接入单相电网的新控制方案

所提议的系统包括与单相电网集成的 1 千瓦混合（光伏和风能）系统。采用基于无差拍的 PI 控制器的新控制方案正弦脉宽调制 (SPWM) 开关设计用于 DC/AC 单相逆变器。该控制器用于具有低总谐波失真 (THD) 的纯正弦输出电压、快速动态响应控制技术，并在来自 PV 和风力系统的输入发生任何变化时保持功率输出恒定，并且输出电压在网格保持不变。即使负载变化，正弦电压输出在 50 Hz 频率下仍保持 230Vrms，并且 THD 低至 2.54%。该控制器证明了在低谐波下将输出电压保持在所需值的刚度和鲁棒性特性。
