pvpumpingsystem.pvpumpsystem.PVPumpSystem¶

class pvpumpingsystem.pvpumpsystem.PVPumpSystem(pvgeneration, motorpump, coupling='mppt', motorpump_model=None, mppt=None, pipes=None, reservoir=None, consumption=None, idname=None)¶

Class defining a PV pumping system made of:

pvgeneration¶

Note that the weather file used here should ideally not smooth the extreme conditions (avoid TMY or IWEC for example). The pvgeneration.modelchain.dc_model must be a Single Diode model if the system is directly-coupled

Type:	pvpumpingsystem.PVGeneration,

motorpump¶

The pump used in the system.

Type:	pvpumpingsystem.Pump

coupling¶

represents the type of coupling between pv generator and pump. Can be ‘mppt’ or ‘direct’

Type:	str,

motorpump_model¶

The modeling method used to model the motorpump. Can be: ‘kou’, ‘arab’, ‘hamidat’ or ‘theoretical’. Overwrite the motorpump.modeling_method attribute if not None.

Type:	str, default None

mppt¶

Maximum power point tracker of the system.

Type:	pvpumpingsystem.MPPT

pipes¶

Type:	pvpumpingsystem.PipeNetwork

reservoir¶

Type:	pvpumpingsystem.Reservoir

consumption¶

Type:	pvpumpingsystem.Consumption

llp¶

Loss of Load Probability, i.e. Water shortage probability. It is None until computed by run_model(), and then it ranges between 0 and 1.

Type:	None or float,

initial_investment¶

Cost of the system at the installation [USD]. It is None until computed by run_model()

Type:	None or float,

__init__(pvgeneration, motorpump, coupling='mppt', motorpump_model=None, mppt=None, pipes=None, reservoir=None, consumption=None, idname=None)¶: Initialize self. See help(type(self)) for accurate signature.

Methods

`__init__`(pvgeneration, motorpump[, …])	Initialize self.
`calc_efficiency`()	Computes the efficiencies between PV array output and motorpump output, between irradiance and PV output, and global efficiency.
`calc_flow`([friction, atol, stop])	Computes the flow at the output of the PVPS, and assigns the value to the attribute ‘flow’.
`calc_reservoir`([starting_soc])	Computes the water volume in the reservoir and extra or lacking water compared to the consumption at any time step.
`define_motorpump_model`(model)
`operating_point`([plot, nb_pts, stop])	Finds the IV operating point(s) of the PV array and the pump (load).
`run_model`([friction, starting_soc])	Comprehensive modeling of the PVPS.
