Abstract

Purpose This paper aims to introduce the quasi impedance source inverter (qZSI)-based static compensator (STATCOM), which is incorporated into the hybrid distributed power generation system for enhancement of power quality. The distributed power generation system includes the photovoltaic (PV), wind energy conversion system (WECS) and battery energy storage system. Design/methodology/approach The WECS is used by the self-excited induction generator (SEIG) and the flywheel energy storage system (FESS). To regulate its terminal voltage and frequency, the SEIG requires adjustable volt-ampere reactive (VAR). A combination of a STATCOM and a fixed condenser bank usually serves to satisfy the VAR demand. The maximum correntropy criterion-based adaptive filter technique (AFT) is proposed to control the qZSI-STATCOM and to guarantee that the voltage at the SEIG terminal is harmonic-free while providing non-linear three-phase and single-phase loads. Findings The coordinated operation of the suggested voltage control and flywheel control systems ensures that load voltage and frequency are retained in their respective values at very low harmonic distortions regardless of wind speed and load variation. The simulation and experimental studies are carried out under different load conditions to validate the efficiencies of the PV-assisted STATCOM. Originality/value To improve system stability and minimize total costs, extra load current sensors can also be avoided. This paper proposes to control the SEIG terminal voltage and harmonic elimination in the standalone WECS systems using maximum correntropy criterion-based AFT with a fuzzy logic controller.

基于准阻抗源逆变器的STATCOM在混合分布式发电系统中提高电能质量的实验验证

目的本文旨在介绍一种基于准阻抗源逆变器（qZSI）的静态补偿器（STATCOM），该补偿器被纳入混合分布式发电系统中，以提高电能质量。分布式发电系统包括光伏（PV）、风能转换系统（WECS）和电池储能系统。设计/方法/方法自激感应发电机（SEIG）和飞轮储能系统（FESS）使用WECS。为了调节其终端电压和频率，SEIG需要可调节的无功伏安（VAR）。STATCOM和固定冷凝器组的组合通常用于满足VAR需求。提出了基于最大相关准则的自适应滤波技术（AFT）来控制qZSI STATCOM，并在提供非线性三相和单相负载的同时保证SEIG端子的电压无谐波。发现建议的电压控制和飞轮控制系统的协调操作确保了负载电压和频率在非常低的谐波失真下保持在各自的值，而与风速和负载变化无关。模拟和实验研究是在不同的负载条件下进行的，以验证光伏辅助STATCOM的效率。原始性/值为了提高系统稳定性并最大限度地降低总成本，还可以避免额外的负载电流传感器。本文提出在独立的WECS系统中，使用基于最大相关准则的AFT和模糊逻辑控制器来控制SEIG端电压和谐波消除。
