It can be possible that bus 2 is the slack bus, so the change on PD and QD will be absorbed by the generator on bus 2, you will not find any changes to the flows over the lines.
Hope that helps! //Yongtao From: [email protected] [mailto:[email protected]] On Behalf Of obokopok andrew Sent: 5. juli 2013 13:41 To: [email protected] Subject: Injecting bus powers in running power flow Hi I am using the following to inject 200 MW and 100MVARs at bus 2 of a simple two bus system, but it is not having any impact on the outcome of the power flow reults. What instruction format should I use to implement bus power injection for a power flow: define_constants; mpc = loadcase('casemazi2'); mpc.bus(2, PD) =200; mpc.bus(2,QD)=-100; runpf(casemazi2); Regards Andrew ************************************************************************************** The contents of this e-mail message and any attachments are confidential and are intended solely for the addressee.
