This paper proposes a control scheme that enhances both the power quality and voltage synchronization of the Self-Excited Induction Generator (SEIG) driven by a wind turbine supplying power to a remote region. A reactive power constraint of SEIG under load disturbances is balanced by a modified Second-Order Generalized Integrator (SOGI) with Fuzzy Logical Controller (FLC) controlled Quasi-Impedance (QZ) source network-based Static Compensator (STATCOM). The combination of STATCOM and the photovoltaic system, battery and flywheel enhances the active power potential of conventional STATCOMs by means of a hybridized STATCOM system. This system is intended for the optimum use of energy generated from renewable energy sources by physical energy storage systems such as flywheels and batteries. This tends to compensate for the deviation of both active and reactive power and hence increase in active power, reliability and system stability. For analyzing device behavior, the dynamic hybrid STATCOM model with FLC dependent ESOGI has been developed. In standalone operation, simulated and experimental findings indicate the increased capability and system efficiency under variable load conditions.

基于准Z源网络的光伏支持STATCOM用于独立WECS的电压和频率控制

本文提出了一种控制方案，该方案可提高由风力涡轮机向偏远地区供电的自励感应发电机 (SEIG) 的电能质量和电压同步。SEIG 在负载扰动下的无功功率约束通过改进的二阶广义积分器 (SOGI) 与模糊逻辑控制器 (FLC) 控制的准阻抗 (QZ) 基于源网络的静态补偿器 (STATCOM) 进行平衡。STATCOM 与光伏系统、电池和飞轮的结合通过混合 STATCOM 系统提高了传统 STATCOM 的有功功率潜力。该系统旨在通过飞轮和电池等物理储能系统优化使用可再生能源产生的能量。这往往会补偿有功和无功功率的偏差，从而提高有功功率、可靠性和系统稳定性。为了分析设备行为，开发了具有 FLC 依赖 ESOGI 的动态混合 STATCOM 模型。在独立运行中，模拟和实验结果表明在可变负载条件下的能力和系统效率有所提高。
