Adding them to columns 3 and 4 of the bus matrix will be equivalent to adding
them to columns 2 and 3 of the gen matrix, assuming the bus is set as a PQ bus
and you are doing a simple power flow. Adding it to bus 5 and 6 of the bus
matrix is not equivalent, since the power (as a constant impedance shunt
element) will depend on the voltage.

Hi Sir. I hope you are doing well. If EVs are to be added as loads on buses
that ave P and Q. Should the load be added in bus data or should I be added as
shunt element or can it be used as negative generator?
You replied
If they are considered as fixed P and Q they can be added to any existing load
in the bus matrix or they can be added as a negative generator. If you add it
as a shunt (in the bus matrix) it will be treated as a constant impedance
element.
If we use Distributed Generators to inject
* Active Power Only
* Reactive Power Only
* Active and Reactive both
* Active but absorb Reactive Power
Can the active and reactive power be added to Column 5 and 6 of {Bus Data Format
1 bus number (positive integer)
2 bus type
PQ bus = 1
PV bus = 2
reference bus = 3
isolated bus = 4
3 Pd, real power demand (MW)
4 Qd, reactive power demand (MVAr)
5 Gs, shunt conductance (MW demanded at V = 1.0 p.u.)
6 Bs, shunt susceptance (MVAr injected at V = 1.0 p.u.)
7 area number, (positive integer)
8 Vm, voltage magnitude (p.u.)
9 Va, voltage angle (degrees)
(-) (bus name)
10 baseKV, base voltage (kV)
11 zone, loss zone (positive integer)
(+) 12 maxVm, maximum voltage magnitude (p.u.)
(+) 13 minVm, minimum voltage magnitude (p.u.)

or they should be added in columns 2 and 3 of the Generator Data Format? or
Will they have the same effect? Thanks
