Thanks Ray But I only use runpf.m as power flow calculation tool. I insert distributed generator at optimal location and optimal size in my study. These two factors are treated by matpower using manual appendix B. For example when inserting 100MW DG at bus2, I change "mpc.bus(2,BUS_ TYPE)=2, mpc.gen(,PG)=100...".
Journal I have read decide optimal location, optimal size and "optimal DG power factor", but in manual appendix B how to change power factor of generator is not written. I want to optimize location , size and power factor. Can matpower treat power factor of generator? regards, ----- Original Message ----- > If you mean that you would like to constrain the power factor of a distributed generator to remain constant as it gets redispatched by the OPF, then, yes, it is possible. You will have to add a user-defined linear equality constraint for each distributed generator. This is already done for dispatchable loads, so you could probably re-use some of the code in makeAvl.m (see also lines 168 and 245 of opf_setup.m). You’ll also want to become familiar with extending the OPF formulation as described in sections 5.3 and 6 of the User’s Manual). > > -- > Ray Zimmerman > Senior Research Associate > B30 Warren Hall, Cornell University, Ithaca, NY 14853 > phone: (607) 255-9645 > > > > On Nov 13, 2013, at 5:08 AM, 小柳拓也 <[email protected]> wrote: > > > Hello, > > > > I have a question about power factor. > > > > I have read many journal about distributed generator insertion. > > > > Journal I have read treat power factor of distributed generator. > > > > I want to treat power factor of distributed generator, but how to treat > > power factor of distributed generator is not written in matpower's > > manual. > > > > On matpower, can treating power factor of distributed generator be > > possible? > > > > If that is possible, please tell me how to treat power factor of > > distributed generator. > > > > Regards, > > > > > > Takuya Koyanagi > > [email protected] > > > > > > > > > > > > > > > >
