Hi Teiji, It is hard to solve the issue without seeing your code or a MWE (Minimum Working Example), but it seems like you have been assigning invalid bus types. You should check the values stored in:
mpc.bus(:,2) or mpc.bus(:,BUS_TYPE) To see if there are any values in this column that are not equal to 1,2,3 or 4. Note that 0 is not a valid number here for BUS_TYPE, which I am guessing you may be setting to simulate a bus contingency. Instead I would set the bus type to 4 and the state of connecting branches to 0. I hope this helps, Samuel Samuel Perkin Kerfisstjórnunarsvið / System Operations Tel / Sími +354 563 / Mobile / Gsm. +354 / [email protected] [cid:test2-Landsnet-feb.2017_c4649f54-1573-4661-b501-76ba1772b7a6.jpg] www.landsnet.is / www.facebook.com/landsnet / www.twitter.com/landsnethf From: [email protected] [mailto:[email protected]] On Behalf Of Teiji Ponishi Sent: 21. maí 2017 09:11 To: [email protected] Subject: Parallel computing of MATPOWER Hello, In order to perform a contingency analysis efficiently, I would like to perform a parallel processing of MATPOWER(Ver. 5.1) using parfor loop in parallel computing toolbox.
