respected sir,
thanks a lot for replying me back .With P & Q i mean active power constraint and reactive power constraint and voltage constraints .Again what can be limits for ieee14 bus if we increase PD by 10% as i want to find out how much losses will increase .The main objective is to find out losses if load changes. If we change load pf ,will it also affect losses. rashmi ________________________________ From: Ray Zimmerman <[email protected]> To: MATPOWER discussion forum <[email protected]> Sent: Mon, 14 March, 2011 8:50:36 PM Subject: Re: powe demand Use scaleload (see help scaleload for details). If you want to increase both P and Q loads proportionally, simply use ... mpc = loadcase('case14'); [mpc.bus, mpc.gen] = scale_load(1.1, mpc.bus, mpc.gen); You don't need any extra constraints since the loads are fixed P and Q values. -- Ray Zimmerman Senior Research Associate 211 Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Mar 12, 2011, at 5:36 AM, Rashmi Agarwal wrote: respected sir, > >this is the first time sending you mail . if i am considering IEEE14 bes and i >want to increase powr demand by 10% but putting P , Qconstraints .how to do >it >and how to add constraint and what can be the limits of constraints. pls help >me > >out. > > > >regards > >rashmi > > > > >
