Abstract

This paper presents a hybrid wind–solar energy system integrating A Doubly-Fed Induction Generator (DFIG) with solar Photovoltaic (PV) modules through a boost converter–battery–inverter interface. A closed-loop control strategy, implemented on a Field Programmable Gate Array (FPGA) (Altium Nanoboard 3000), ensures stable stator voltage and frequency for isolated load operation. Reactive power compensation is achieved via a 2 kVAR capacitor at the stator side. The solar PV subsystem features a current-sensor-based Maximum Power Point Tracking (MPPT) algorithm using the Converter Output Current Based (COCB) method, which operates independently of panel parameters and switches to constant voltage mode when the battery is fully charged. Hardware tests with a solar simulator and real panels confirm improved tracking accuracy and reduced oscillations over conventional approaches. Experimental validation confirms the system’s reliability and adaptability under varying conditions, highlighting its potential for efficient energy management in standalone applications. Results verified its effectiveness, achieving a Total Harmonic Distortion (THD) below 3% and exhibiting rapid dynamic performance.

风力DFIG和太阳能光伏可持续发电的实验研究及控制策略

提出了一种通过升压变换器-电池-逆变器接口将双馈感应发电机（DFIG）与太阳能光伏（PV）组件集成在一起的混合风能-太阳能系统。在现场可编程门阵列（FPGA）（Altium Nanoboard 3000）上实现的闭环控制策略确保了隔离负载运行时稳定的定子电压和频率。无功功率补偿通过定子侧的2kvar电容器实现。太阳能光伏子系统采用基于电流传感器的最大功率点跟踪（MPPT）算法，采用基于转换器输出电流（COCB）的方法，该算法独立于面板参数运行，并在电池充满电时切换到恒压模式。用太阳能模拟器和真实面板进行的硬件测试证实，与传统方法相比，跟踪精度得到提高，振荡减少。实验验证证实了该系统在不同条件下的可靠性和适应性，突出了其在独立应用中高效能源管理的潜力。实验结果验证了该方法的有效性，实现了总谐波失真（THD）低于3%，并具有快速的动态性能。
