Re: Difference between System and Load Losses

Arun,
  I don’t think there is a “load losses” function in MATPOWER that returns how 
much load is lost akin to a LOLE calculation. If you want to calculate loss of 
load for reliability or restoration calculations, then you can run an optimal 
power flow with dispatchable loads. (set very high price coefficients for the 
loads so that they are not curtailed unless there is a system need). Read 
section 6.4.2 of the MATPOWER manual.

Subject: Difference between System and Load Losses

Hi,

>From the manual, I see that get_losses() returns branch series losses (system 
>losses).
Is there an equivalent method to compute “load losses” that represents in 
understandable units (e.g. total MW), the consequence of loss of one or more 
transformers?

This unit would be convenient to measure how much load capacity is at loss and 
how gradual recovery of transformers brings back the entire system to original 
working state after a few days.

Thanks
