Mathematical Modeling and Simulation Photovoltaic Converter Operation When Varying Parameters

Abstract

The paper presents a method of mathematical modelling of a solar converter using the results of full-scale testing. The advantages of analytical modelling method applied to photovoltaic systems are also presented; this is because the model parameters are directly measurable by data acquisition from the photovoltaic field consisting of photovoltaic cells type Z - (mono-crystalline photovoltaic). The model parameter also includes both the photovoltaic cell characteristics as a device (forming the photovoltaic field) and the temperature influence on the photovoltaic field performance. The results of the photovoltaic model numerical simulation (PV) to the major parameters conversion variation can also be used to design and assess the performance of low and medium - power photovoltaic systems operating in single regime (to supply the home appliances).
