Annual power losses

2012-03-21 Thread Ruhaizad Ishak
Dear All,   I am new in using this Matpower tool and wish someone could guide me on how to calculate annual power losses (52 weeks) for IEEE 24 bus system.   How can I pose different set of load values to the system and then calculate the total losses of the test system.    Similarly, I also wish

I think there exist mutliple solutions. I would propose the following scheme: run the powerflow- calculation multiple times in order to simulate the time horizon. for example: if your load changes with a granularity of 1 hour, you have to do 24x7x52 powerflow calclations; write a script that exe

Hmmm, yes, unfortunately, I believe that the DC line implementation modifies things in a way that breaks the normal handling of other linear constraints by changing the number of generators. I'm pretty sure that simply adding additional columns of zeros to the right side of your A matrix to make
