Dear Sk. Md. Golam Mostafa,
Please add “define_constants” before the use of “results.bus(:, VM)” or “results.gen(:, PG)”. The constants such as “VM” and “PG” are defined by “define_constants” in MATPOWER.

Golam Mostafa Sent: Saturday, December 17, 2016 10:49 PM To: MATPOWER discussion forum Subject: Re: Helping regarding Matpower function Dear Sir, I tried to use Table 4-1 in Matpower User's Manual. To find Bus voltage I used results.bus(: ,VM) but it says undefined variable 'VM'. Similarly for power I used results.gen(: ,PG); Again it says it says undefined variable 'PG'. Would you please suggest me, what was the wrong? Best Regardes. Sk. Md.

Flows are recorded as powers, so to get the currents, you’ll need to compute them yourself from the corresponding power and voltage. Ray On Dec 13, 2016, at 10:26 AM, Sk. Md.

I run 16 bus with results = runpf(mycase);. & I got losses with a command total_system_real_losses = sum(real(get_losses(results))); a Now, How can I will get voltage of buses, & voltage in a certain bus no. I also need current & power. Thank you so much in advance. Sk. Md. Golam Mostafa Masters student EPSM, AIT,Thailand
