Photovoltaic panel Spice modelling

Abstract

Článek popisuje univerzální Spice model, který je vhodný pro modelování fotovoltaického panelu, a to především jeho stejnosměrných charakteristik. Model je založen na jednoduchém schématu, jehož parametry jsou přizpůsobeny tak, aby výsledná charakteristika kopírovala naměřené hodnoty. Jsou představeny dva typy model. Jsou to jednoduchý model a komplexní model. Jednoduchý model je platný pouze pro fotovoltaické panely s konstantní šířkou PN přechodu (volitelné jsou pouze délka a množství těchto přechodů). Komplexní model umožňujeměnit také šířku PN přechodu. Jednoduchý model vykazuje lepší přesnost, která je typicky lepší než 5% zatímco komplexní model má přesnost typicky lepší jen 15% (pro osvětlení v rozsahu 20lx až 2000lx). ; Research described in the paper has been supported by the project EnSO, Electronic Components and Systems For European Leadership Joint Undertaking in collaboration with the European Union's H2020 Framework Programme (H2020/2014-2020) and National Authorities, under grant agreement n° 692482 and partially by Smart Access Control for Smart Buildings (SACON), No. 12708 ; The paper presents a universal Spice model that can be used for modelling the photovoltaic panels (PV) – namely the DC characteristics. The model was built on simplified schematic and fitting its parameters to the measured data. There were developed two types of the models – the simple model and the full model. The simple model is valid only for PVs with constant width of the PN junction strip (only the number and length are scalable). The full model allows user to set also the PN junction’s width. The simple model exhibits better accuracy, typically better than 5 %, while the full model’s accuracy is typically lower than 15 % (for illumination in the range from 20 lx to 2000 lx).
