“…Manufacturers are used to summarize these nonlinear relations by providing in datasheets a given number of electrical parameters, the most typical being those associated to the so-called remarkable points: Modeling PV arrays is clearly a key task in order to provide designers flexible and accurate instruments for predicting the energy budget under different working conditions [18][19][20][21][22][23][24][25][26][27][28]. The most typically adopted strategy is to represent a model by means of an equivalent circuit [29,30].…”

Abstract:Reproducibility of experimental conditions is a fundamental requirement for designing energy efficient, self-sustainable wireless sensor networks (WSNs). At the same time, it represents a significant challenge because of the variability and the unpredictability of many energy harvesting sources, and because of the dynamic operating conditions of the devices to which energy is supplied. Energy source emulation is considered a suitable solution to enable the exploration of the design space of networked embedded systems. However, in order to guarantee the compatibility with real-time performance of resource-constrained embedded platforms, particular attention has to be paid to the complexity of the models. In this paper, we propose an approach aimed at tuning the complexity of models of photovoltaic (PV) arrays implemented on a target embedded emulator, featuring low cost and small form factor. Experimental results performed on different models of PV array, show that the proposed solution is flexible and accurate enough to meet the real-time constraints of typical sensor networks applications without impairing the precision in the emulation of the energy sources.

“…This single-diode R p model or 5-p model is the most widely used and accepted model found in the literature (Chatterjee et al 2011;Chenni et al 2007;Chin et al 2015;Ciulla et al 2014;Mahmoud et al 2012;Patel and Agarwal 2008;Brano et al 2010Brano et al , 2012. Most of the research has been done on the improved 5-p model and its parameter (I L , I 0 , V T , R s , R p ) extraction procedure (Soto et al 2006;Brano et al 2010Brano et al , 2012Sera et al 2007;Chatterjee et al 2011;Villalva et al 2009;Ishaque et al 2011).…”

In this paper, all the models of PV cell, namely ideal single-diode model, single-diode R s model, single-diode R p model, the two-diode model, and the three-diode model, have been discussed. SPICE simulation is done to evaluate the impact of model parameters on the operation of PV cell. The effects of the parameters are discussed. The photocurrent, I L , is proportional to irradiance, and the series resistance, R s , reduces the short-circuit current and fill factor. The parallel resistance, R p , reduces the open-circuit voltage, and both the diffusion diode and recombination diode reduce the open-circuit voltage value and fill factor. Finally, it is shown that an increase in cell operating temperature reduces the open-circuit voltage and fill factor and thus degrades the performance significantly.

Abstract:In order to reduce the mismatch effect caused by non-uniform shadows in PV arrays, reconfigurable interconnections approaches have been recently proposed in the literature. These systems usually require the knowledge of the solar radiation affecting every solar module. The aim of this work is to evaluate the effectiveness of three irradiance estimation approaches in order to define which can be well suited for reconfigurable PV arrays. It is presented a real-time solar irradiance estimation device (IrradEst), implementing the three different estimation methods. The proposed system is based on mathematical models of PV modules enabling to estimate irradiation values by sensing a combination of temperature, voltage and current of a PV module. Experimental results showed generally good agreement between the estimated irradiances and the measurements performed by a standard pyranometer taken as reference. Finally one of the three methods was selected as possible solution for a reconfigurable PV system.
