fProd: Performance of a PV system

Description

Simulate the behaviour of a grid connected PV system under different conditions of irradiance and temperature.

Usage

fProd(Inclin = data.frame(Gef = 800, Ta = 25),
    modulo = list(Vocn = 57.6, Iscn = 4.7, Vmn = 46.08, Imn = 4.35,
        Ncs = 96, Ncp = 1, CoefVT = 0.0023, TONC = 47),
    generador = list(Nms = 12, Nmp = 11),
    inversor = list(Ki = c(0.01, 0.025, 0.05), Pinv = 25000,
        Vmin = 420, Vmax = 750, Gumb = 20),
    EffSys = list(ModQual = 3, ModDisp = 2, OhmDC = 1.5, OhmAC = 1.5,
        MPP = 1, TrafoMT = 1, Disp = 0.5))

Arguments

Inclin

data.frame including at least a component named Gef (effective irradiance, W/m²) and another named Ta (ambient temperature, $^{\circ}{\rm C}$).

modulo

list of numeric values with information about the PV module, [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

generador

list of numeric values with information about the generator, [object Object],[object Object]

inversor

list of numeric values with information about the DC/AC inverter, [object Object],[object Object],[object Object],[object Object]

EffSys

list of numeric values with information about the system losses, [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Value

• data.frame including Inclin and the next components:
• Tc
  cell temperature, $^{\circ}{\rm C}$
• Voc, Isc, Vmpp, Impp
  open circuit voltage, short circuit current, MPP voltage and current, respectively, in the conditions of irradiance and temperature provided by Inclin
• Vdc, Idc
  voltage and current at the input of the inverter. If no voltage limitation occurs (according to the values of inversor$Vmax and inversor$Vmin), their values are identical to Vmpp and Impp. If the limit values are reached a warning is produced
• Pdc
  power at the input of the inverter, W
• Pac
  power at the output of the inverter, W
• EffI
  efficiency of the inverter
