It sounds like your P and Q are branch flow values, not nodal loads, so no they
should not be used as loads in the bus matrix.

Hi Ray and thank you for your reply,
i will try to make my case more clear. I am studying a radial transmission
network (150 kV). There are 3 branches directly connected to a station. I am
thinking of using this station as a “sink” (a load for Matpower) that collects
the power generated by the wind power plants in the network.
My final goal is to do an extended optimal power flow, using some custom
constraints, to optimize size and location of energy storage in order to avoid
wind curtailment by the transmission operator.
I have data of P, Q and I of branches, and V at the nodes (intersection of
branch and power plant). Should i put those data (P,Q) in the 3rd and 4th
column of the bus matrix data despite they are not load buses? Or should i do
something different in my scenario?
I have put an image to semplify things.
Hope this time i have make it more clear, thank you again for your time,
Davide Maglione

Oggetto: Re: Bus, Loads and Generators question
It isn’t completely clear what data you have to create your case, but you
definitely need both load and generation for the system to make any sense.
Total generation is equal to total load plus losses, so you need both.
And dispatchable load refers to loads whose quantities are not fixed, but can
vary depending on the price.

Hello,
For my thesys work i am trying to recreate a trasmission network with high
penetration of wind power. I have some doubts on how to consider my buses,
because in my network there are no loads but only generators and i am
considering the buses as the nodes of the system.
I have V,I and P datas of each n_i node, so can i put in the 3rd and 4th column
of the bus matrix those flow data despite they are not load buses?
Finally, what do you mean with “dispatchable load”?
Thank you very much,
best regards.
