Depending on the choice of **mpopt.pf.current_balance** and **mpopt.pf.v_cartesian**, it uses the power or current balance equations in polar and Cartesian coordinates. newtonpf() can be improved for some parts. \r\n\r\n- Each variant is also implemented and named as **newtonpf_PP** (original newtonpf using power balance in polar coordinates), **newtonpf_PC** (NR using power balance in Cartesian coordinates), **newtonpf_CP** (NR using current balance in polar coordinates) and **newtonpf_CC** (NR using current balance in Cartesian coordinates).\r\n\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/MATPOWER/matpower/issues/comments/465676326","html_url":"https://github.com/MATPOWER/matpower/pull/43#issuecomment-465676326","issue_url":"https://api.github.com/repos/MATPOWER/matpower/issues/43","id":465676326,"node_id":"MDEyOklzc3VlQ29tbWVudDQ2NTY3NjMyNg==","user":{"login":"BaljaaSS","id":15252654,"node_id":"MDQ6VXNlcjE1MjUyNjU0","avatar_url":"https://avatars3.githubusercontent.com/u/15252654?v=4","gravatar_id":"","url":"https://api.github.com/users/BaljaaSS","html_url":"https://github.com/BaljaaSS","followers_url":"https://api.github.com/users/BaljaaSS/followers","following_url":"https://api.github.com/users/BaljaaSS/following{/other_user}","gists_url":"https://api.github.com/users/BaljaaSS/gists{/gist_id}","starred_url":"https://api.github.com/users/BaljaaSS/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/BaljaaSS/subscriptions","organizations_url":"https://api.github.com/users/BaljaaSS/orgs","repos_url":"https://api.github.com/users/BaljaaSS/repos","events_url":"https://api.github.com/users/BaljaaSS/events{/privacy}","received_events_url":"https://api.github.com/users/BaljaaSS/received_events","type":"User","site_admin":false},"created_at":"2019-02-20T17:27:27Z","updated_at":"2019-02-20T17:27:27Z","author_association":"NONE","body":"Correct. Moreover, we need to use one of the equations (2) and (3) as you can find in the report to handle PV buses in power cartesian variant. But it is also okay to write like that.\r\n\r\nI will check #40 and let you know my feedback on that. We can arrange a conversation on three-phase modeling through Skype. I am also attending SIAM CSE19 and IEEE PES GM 19 conferences in the USA. If you are attending one of these conferences we can also meet there as well. "}}
