%T Comparative Study and Validation of Photovoltaic Model Formulations for the IBPSA Modelica Library based on Rooftop Measurement Data
%8 10/2023
%X <p>Domain-overarching system models are crucial to investigate sector coupling concepts. Specifically, the coupling of building and electrical energy systems becomes crucial to integrate renewable energy sources such as photovoltaic&nbsp;<span style="font-size: 13.008px;">power systems (PV). For such interdisciplinary&nbsp;</span><span style="font-size: 13.008px;">models, Modelica is a suitable language. However, most&nbsp;</span><span style="font-size: 13.008px;">open-source Modelica libraries are either domain-specific&nbsp;</span><span style="font-size: 13.008px;">or lack simple-to-parameterize PV models. We close this&nbsp;</span><span style="font-size: 13.008px;">gap by developing a PV model for the IBPSA Modelica&nbsp;</span><span style="font-size: 13.008px;">Library. The model comprises two I-V-characteristic models&nbsp;</span><span style="font-size: 13.008px;">and three mounting-dependent cell temperature models.&nbsp;</span><span style="font-size: 13.008px;">The I-V-characteristic models follow a single- and&nbsp;</span><span style="font-size: 13.008px;">two-diodes approach. This study uses measurement data&nbsp;</span><span style="font-size: 13.008px;">from a rooftop PV system in Berlin, Germany, for validation.&nbsp;</span><span style="font-size: 13.008px;">The focus lies on comparing the implemented singleand&nbsp;</span><span style="font-size: 13.008px;">two-diodes approach. Results prove that both models&nbsp;</span><span style="font-size: 13.008px;">accurately calculate the modules’ DC power output and cell temperature.</span></p>
