getPVInfo
Gets the information for all PV plants in the circuit
Contents
Syntax
PV = getPVInfo(DSSCircObj); PV = getPVInfo(DSSCircObj, pvNames);
Description
Function to get the information about the PV plants in the circuit and return a structure with the information. If the optional input of pvNames is filled, the function returns information for the specified subset of PV installations, excluding the miscellaneous parameters mentioned in the outputs below.
Inputs
- DSSCircObj - link to OpenDSS active circuit and command text (from DSSStartup)
- pvNames - optional cell array of PV names to get information for
Outputs
PV is a structure with all the parameters for the PV plants in the active circuit. Fields are:
- name - Name of the PV source.
- numPhases - Number of phases associated with the PV.
- busName - Name of the associated bus.
- enabled - {1|0} indicates whether this element is enabled in the simulation.
- current - average phase current output
- coordinates - Coordinates for the PV bus
- distance - Line distance from the PV bus to the substation, obtained from getBusInfo.
- phaseVoltages - Value of voltage magnitudes calculated from the complex voltage returned by OpenDSS. Length is always 3, returning 0 for phases not on the bus
- phaseVoltagesPU - Per-unit value of voltage magnitudes calculated from the complex per-unit voltage returned by OpenDSS. Length is always 3, returning 0 for phases not on the bus.
- voltage, voltagePU, voltagePhasorPU, phaseVoltages, phaseVoltagePhasors, ... phaseVoltagePhasorsPU, phaseVoltagesLL, phaseVoltagesLLPU, voltageLL, voltageLLPU - voltages and voltage phasors
- seqVoltages, cplxVoltages, seqCurrents, cplxSeqCurrents - zero, positive, and negative sequence voltages and currents magnitude or complex phasors
- phasePowerReal - 3-element array of the real components of each phase's complex power injected by generator. Phases that are not present will return 0.
- phasePowerReactive - 3-element array of the imaginary components of each phase's complex power injected by generator. Phases that are not present will return 0.
- powerReal - Total phasePowerReal.
- powerReactive - Total phasePowerReactive.
- losses - total real and imaginary power losses
- phaseLosses - real and imaginary power losses
- kW, kvar, kva - Rated power of the PV
- kV - Rated voltage.
- PF - Rated power factor of the PV.
- pmpp - DC power rating of the PV system.
