Correntropy‐based parameter estimation for photovoltaic array model considering partial shading condition

Abstract: Analytical modelling of photovoltaic (PV) array is crucial for studying the current-voltage (I-V) characteristic of PV array and maximum power point tracking. A PV array model generally contains some undetermined parameters and the values of the parameters cannot be measured by sensors. It is difficult to correctly determine those model parameters. They should be estimated based on experimental data. Since the experimental data gathered from the solar panel equipment usually contain random and gross errors, a … Show more

“…The characteristics of the module and also the corresponding electrical parameters of the equivalent single-diode circuit model at STC is specified in Table 2. It should be noted that the reference P − V curve can be obtained numerically at any environmental condition with known (measured) G and T values by updating electrical parameters through Equations ( 3) to (6) and substitution in the main I − V characteristic formula. The generated numerical P − V curve is precise and doesn't require a physical cell/module as the reference.…”

“…Hence, by known values of the single-diode circuit model for a single cell/module at STC, it is possible to obtain the P − V characteristic of the PV system at STC according to Equation (2). Moreover, by measuring the G and T variables, the P − V characteristic of the PV system can be achieved at any other environmental conditions by substitutions of updated parameters Equations ( 3) and (6) in Equation (2). Therefore, to attain the P − V curve of a PV system, the five unknown parameters of a single-diode circuit model for a cell/module are required.…”
