A Novel Solar Photovoltaic Fed TransZSI-DVR for Power Quality Improvement of Grid-Connected PV Systems

Abstract

En este artículo, se propone un nuevo restaurador de voltaje dinámico (DVR) alimentado por energía solar fotovoltaica basado en un inversor de fuente Trans-Z (TransZSI) para mejorar la calidad de la energía de los sistemas fotovoltaicos (PV) en la red. El DVR es un compensador electrónico de potencia que se utiliza para inyectar la tensión deseada en el punto de acoplamiento común (PCC) según la perturbación de tensión. En el DVR propuesto, en lugar del VSI tradicional, se presenta TransZSI con méritos sobresalientes de buck/boost, un rango más amplio de ganancia de impulso de voltaje, menos componentes pasivos y menor tensión de voltaje. Para una detección eficiente, una mitigación precisa de las perturbaciones de voltaje y también una disminución de los armónicos de voltaje inyectados, se propone una plantilla de vector de unidad híbrida con un método de control de impulso constante máximo (UVT-MCBC) para TransZSI-DVR. El rendimiento de la TransZSI-DVR propuesta con UVT-MCBC se ha analizado en condiciones de pandeo severo, ligero pandeo con armónicos, hinchamiento e interrupción. Los estudios comparativos y los resultados de la simulación han demostrado la efectividad de la TransZSI-DVR propuesta, a diferencia de la ZSI-DVR y la VSI-DVR tradicionales. El TransZSI-DVR en el sistema fotovoltaico ha mitigado la caída/hinchazón/interrupción del voltaje. También ha mejorado la calidad de la energía tanto de la tensión inyectada al PCC como de la tensión de salida del sistema fotovoltaico.

Dans cet article, un nouveau restaurateur de tension dynamique (DVR) alimenté par PV solaire basé sur l'onduleur Trans-Z-source (TransZSI) est proposé pour améliorer la qualité de l'énergie des systèmes photovoltaïques (PV) sur le réseau. DVR est un compensateur électronique de puissance utilisé pour injecter la tension souhaitée au point de couplage commun (PCC) en fonction de la perturbation de tension. Dans le DVR proposé, à la place du VSI traditionnel, TransZSI avec des mérites exceptionnels de buck/boost, une gamme plus large de gain d'amplification de tension, moins de composants passifs et une contrainte de tension plus faible, est mis en avant. Pour une détection efficace, une atténuation précise des perturbations de tension et une diminution des harmoniques de tension injectées, une méthode de modèle de vecteur d'unité hybride avec contrôle d'amplification à constante maximale (UVT-MCBC) est proposée pour TransZSI-DVR. La performance du TransZSI-DVR proposé avec UVT-MCBC a été analysée sous un affaissement sévère, un léger affaissement avec des harmoniques, une houle et une interruption. Les études comparatives et les résultats de simulation ont montré l'efficacité du TransZSI-DVR proposé, par opposition aux ZSI-DVR et VSI-DVR traditionnels. Le TransZSI-DVR dans le système PV a atténué l'affaissement/la houle/l'interruption de tension. Il a également amélioré la qualité de l'alimentation de la tension injectée à la tension de sortie du système PCC et PV.

In this article, a new solar PV fed Dynamic Voltage Restorer (DVR) based on Trans-Z-source Inverter (TransZSI) is proposed to improve the power quality of on-grid Photovoltaic (PV) systems. DVR is a power electronic compensator using for injecting the desired voltage to the Point of Common Coupling (PCC) as per the voltage disturbance. In the proposed DVR, in place of traditional VSI, TransZSI with outstanding merits of buck/boost, a broader range of voltage boost gain, fewer passive components, and lower voltage stress, is put forth. For efficient detection, accurate voltage disturbances mitigation, and also lessening the injected voltage harmonics, a hybrid Unit Vector Template with Maximum Constant Boost Control (UVT-MCBC) method is proposed for TransZSI-DVR. The performance of the proposed TransZSI-DVR with UVT-MCBC has been analyzed under severe sag, slight sag with harmonics, swell, and interruption. The comparative studies and simulation results have shown the effectiveness of the proposed TransZSI-DVR, as opposed to traditional ZSI-DVR and VSI-DVR. The TransZSI-DVR in the PV system has mitigated voltage sag/swell/interruption. It has also improved the power quality of both the injected voltage to the PCC and PV system's output voltage.

في هذه المقالة، يقترح مرمم جهد ديناميكي جديد يعمل بالطاقة الشمسية الكهروضوئية (DVR) يعتمد على العاكس عبر المصدر Z (TransZSI) لتحسين جودة الطاقة للأنظمة الكهروضوئية (PV) على الشبكة. DVR هو معوض إلكتروني للطاقة يستخدم لحقن الجهد المطلوب إلى نقطة الاقتران المشترك (PCC) وفقًا لاضطراب الجهد. في مسجل الفيديو الرقمي المقترح، بدلاً من VSI التقليدي، يتم طرح TransZSI مع مزايا بارزة من باك/بوست، ومجموعة أوسع من زيادة زيادة الجهد، ومكونات سلبية أقل، وإجهاد جهد أقل. للكشف الفعال، والتخفيف الدقيق من اضطرابات الجهد، وكذلك تقليل توافقيات الجهد المحقون، يتم اقتراح قالب متجه وحدة هجين مع طريقة التحكم في التعزيز الثابت الأقصى (UVT - MCBC) لـ TransZSI - DVR. تم تحليل أداء TransZSI - DVR المقترح مع UVT - MCBC تحت ترهل شديد وترهل طفيف مع توافقيات وتضخم وانقطاع. أظهرت الدراسات المقارنة ونتائج المحاكاة فعالية TransZSI - DVR المقترحة، على عكس ZSI - DVR التقليدي و VSI - DVR. قام TransZSI - DVR في النظام الكهروضوئي بتخفيف ترهل/انتفاخ/انقطاع الجهد. كما أنها حسنت جودة الطاقة لكل من الجهد المحقون لجهد خرج نظام PCC و PV.
