PVSystems Class

Initializes a new instance of the PVSystems class

Array of strings with all PVSystem names in the circuit.

Number of PVSystem objects in active circuit.

Name of the loadshape for a daily PVSystem profile.

Name of the load shape to use for duty cycle dispatch simulations such as for solar ramp rate studies. Must be previously defined as a Loadshape object. Typically would have time intervals of 1-5 seconds.

Sets the first PVSystem active. Returns 0 if no more.

Get/set active PVSystem by index; index is 1-based: 1..count

Get/set the present value of the Irradiance property in kW/m²

Returns the current irradiance value for the active PVSystem. Use it to know what's the current irradiance value for the PV during a simulation.

Get/set kvar output value

Get/set Rated kVA of the PVSystem

get kW output

Sets the active PVSystem by Name.

Sets the next PVSystem active. Returns 0 if no more.

Get/set the power factor for the active PVSystem

Gets/sets the rated max power of the PV array for 1.0 kW/sq-m irradiance and a user-selected array temperature of the active PVSystem.

Array of PVSYSTEM energy meter register names

Array of doubles containing values in PVSystem registers.

Name of the sensor monitoring this element.

Temperature shape to use for daily simulations. Must be previously defined as a TShape object of 24 hrs, typically. The PVSystem element uses this TShape to determine the Pmpp from the Pmpp vs T curve. Units must agree with the Pmpp vs T curve.

Temperature shape to use for duty cycle dispatch simulations such as for solar ramp rate studies. Must be previously defined as a TShape object. Typically would have time intervals of 1-5 seconds. Designate the number of points to solve using the Set Number=xxxx command. If there are fewer points in the actual shape, the shape is assumed to repeat. The PVSystem model uses this TShape to determine the Pmpp from the Pmpp vs T curve. Units must agree with the Pmpp vs T curve.

Temperature shape to use for yearly simulations. Must be previously defined as a TShape object. If this is not specified, the Daily dispatch shape, if any, is repeated during Yearly solution modes. The PVSystem element uses this TShape to determine the Pmpp from the Pmpp vs T curve. Units must agree with the Pmpp vs T curve.

Dispatch shape to use for yearly simulations. Must be previously defined as a Loadshape object. If this is not specified, the Daily dispatch shape, if any, is repeated during Yearly solution modes. In the default dispatch mode, the PVSystem element uses this loadshape to trigger State changes.

Returns the low-level handle of the current OpenDSS/DSS-CAPI instance.
