RE: Multiple Slack bus
Hi Ahmad, As Ray said, Matpower doesn’t do distributed slack, but it isn’t too difficult to simulate multiple slack buses by wrapping matpower load flow functions in a loop. Here is some rough pseudocode to get you started: 1) Define generator participation factors 2) Run load flow in Matpower 3) Determine change in slack bus generation 4) Distribute this change in generation among generators, based on their participation factors 5) Return to step 2 unless the change in slack bus is near-zero To ensure convergence, you may also need to account for changes in losses (as you are trying to balance Generation = Load + Losses) Kind regards, Samuel Samuel Perkin Kerfisstjórnunarsvið / System Operations Tel / Sími +354 563 / Mobile / Gsm. +354 / samu...@landsnet.is [cid:test2-Landsnet-feb.2017_c4649f54-1573-4661-b501-76ba1772b7a6.jpg] www.landsnet.is / www.facebook.com/landsnet / www.twitter.com/landsnethf From: bounce-122061961-76238...@list.cornell.edu [mailto:bounce-122061961-76238...@list.cornell.edu] On Behalf Of Ahmad Sadiq Abubakar Sent: 20. nóvember 2017 12:02 To: MATPOWER discussion forum <matpowe...@list.cornell.edu> Subject: Multiple Slack bus Dear all, Can I run power with multiple slack bus in matpower? -- Engr.

Re: Multiple Slack bus
No, MATPOWER does not currently implement distributed slack.
