About ignoring some bus voltage limit constraints

2019-01-18 Thread Meraj Fouad
Hi , How are you all doing? I am using "runopf" in MATPOWER. But I want MATPOWER to consider some particular bus voltage limit constraints. For example, in case9 bus system, MATPOWER should consider the voltage limits ( 0.9 and 1.1) of only bus 5 to 8. Is there any idea how can I do that? Best

Hi Hasan, I would say, just relax the limits of rest of the buses from bus matrix in case9.m file and keep ( 0.9 and 1.1) for 5 to 8. Thanks Mirish On Fri, Jan 18, 2019 at 10:19 PM Meraj Fouad wrote: > Hi , > How are you all doing? > > I am using "runopf" in MATPOWER. But I want MATPOWER to

Hi Mirish, Thank you for your response. can you make it a bit more clear? what do you mean by relaxing? Best regards On Fri, Jan 18, 2019 at 4:53 PM Mirish Thakur wrote: > Hi Hasan, > > I would say, just relax the limits of rest of the buses from bus matrix in > case9.m file and keep ( 0.9 and

Hi Hasan, If you open case9.m you'll see the bus matrix. You need to change the value of *Vmax Vmin *values from bus matrix like I changed it for buses you want. I think you need to do this: %% bus data % bus_i type Pd Qd Gs Bs area Vm Va baseKV zone Vmax Vmin mpc.bus = [ 1 3 0 0 0 0 1 1 0 345 1 *

Hi mirish Just tried this But in this scenario, the runopf function gives completely different result. What I want that, for a particular load condition, bus 5-8 reaches to their max limit 1.1. Other buses are always within the safe range. So I want to reduce the number of constraints by
