“…where η inv represents the power converter efficiency, P inv_dc the inverter power input, and P inv_ac is the inverter power output. As it can be observed, the efficiency depends on the power output of the converter and remains almost constant for output values above 0.3 per unit (pu) [128]. In this way, in order to model this technology, the Jantsch model was used [129] and it is shown in Equation (6).…”

“…The unidimensional model of Jantsch [17][18][19] is expressed by (1), where k 0 , k 1 , and k 2 are the coefficients to be calculated for any inverter, and c is the load factor, which is defined as the ratio between the power that is processed at a certain instant and the nominal power of the inverter. In (1), the part of the losses that are independent of the generated power (constant losses) are weighted by k 0 , the losses that linearly depend on the load factor are weighted by k 1 and the losses with a quadratic dependence on the load factor are weighted by k 2 .…”

“…These models can be classified as unidimensional and bidimensional, depending on whether they only take into account the generated power, or if they consider both the power generation and the DC voltage at the input of the inverter. Some unidimensional and bidimensional models were studied in [17][18][19][20][21][22][23][24][25].…”

“…For MBE% errors, the Sandia model results were better than the Jantsch model. Finally, in [128] it is concluded that the Sandia and Jantsch mathematical models are reliable for representing the energy conversion efficiency of an inverter for computer simulations and consequently, to generate estimations of energy production of PVPPs under different climatic conditions.…”
