Optimal Power Flow - Part 2 MATPOWER

[@solo605]

"I am working on a final dissertation on the topic of HVDC. Could you suggest a program idea on this topic, preferably using MATLAB (matACDC)?

[@younesgasmi8518]

thank you sir , how can i generate the dataset using stochastic load

[@solo605]

How can I modify the node that has a converter in the program (matacdc)

[@CodeAutopro]

can be shared for source code?

[@joshuadarville1915]

Nice content for scientists! How do you export 3D parameter in an AMPL data file for the IEEE18 bus? I would like to export a 2D parameter for different scenarios.

hi, How do I compare cases in matpower?

[@sb.sb.sb.]

what do you mean by compare? like powerflow in lines?

[@sevgiduman7318]

yes@@sb.sb.sb.

[@do_not_reply4784]

dear sir , how can we include renewable energy sources in the opf using matlpower ?

[@pradipkhatri8481]

How to perform radial power flow sir??

[@dhimanbanerjee1177]

Sir, your programming videos are very helpful. As a beginner, I would like to ask you how to perform dynamic/ 24 hour optimal power flow using Matlab programming?

[@sb.sb.sb.]

So matpower has some loads. Step 1 is to vary the loads to get data for 24 hours (say 1 min data sample). You can get this data by following the load curve given in matpower, or downloading some real dataset and intrapolating to increase data size. Then you do a loop and run the opf in the loop.

Thank you for great video sir !. One query.. how to check line capacity (transmission line power flow limit) of each branch?

[@sb.sb.sb.]

if you go to MATPOWER manual, you can look up table columns for Rating A, Rating B and Rating C. These are line limits, and I think they are column 11. it is written in the manual

[@shubhamtandon6483]

Hi quick question for you, How are you supposed to set line current ratings. I believe you need to change the rate_a; rate_b and rate_c in the branch correct? the limit is current(kA)*basekV. I am not sure if I understand how p.u. is used here. If you have any knowledge of this please let me know.

[@sb.sb.sb.]

matpower uses line rating for powerflow. if you are looking to work with PMUs and current flow, you need to calc branch current limit from power flow limit by using the base values

Is there code available for 42 bus system in matpower ???Please provide if u have it.

[@sb.sb.sb.]

i do not see 42 bus system. what kind of system is this? distribution or transmission?

[@kinzamalik1861]

hi, how to perform apply changes function on gmlc case, plz make a video on it

[@sb.sb.sb.]

sure, I will try. can you please tell me more details on it

[@miftakulfarid1064]

Hello sagnik. Can you tell me how to change method in matpower, from NR's method to Gauss Seidel's or fast decoupled's method. I'm beginner in matlab. Thank you

[@sb.sb.sb.]

you can use gausspf matpower.org/docs/ref/matpower5.0/gausspf.html

[@miftakulfarid1064]

@@sb.sb.sb. thank you bro

[@gs7896]

Hello sagnik . It's nice to see video on opf. Can you please tell me how to use this matpower for opf. Is it same as matlab writing code and executing? Or it has some network

[@sb.sb.sb.]

same as matlab, i advise read the entire manual you will learn a lot

[@naimaagouzoul6888]

I change the voltage magnitude in pv buses in matpower after raning power flow the voltage is return to 1 how Can i renforce the change

[@sb.sb.sb.]

how did u change the v magnitude? where exactly in matpower?

[@naimaagouzoul6888]

@@sb.sb.sb. this the question i wont to Ask how Can i make changes

Hi, how can I add a new casedata to matpower?

[@sb.sb.sb.]

if you want to add a new case, you have to create a mpc file that follows the same order. first, obtain all bus, line, gen data for the new case, arrange them in the same format as say IEEE 30 bus, then you can load and run the case. The format should match as any mpc file. take a look at the test cases already there. do u know which system you are working with?

[@MahsaOmri]

@@sb.sb.sb. I'm gonna run the code for a modified IEEE 33-bus distribution system.

[@sb.sb.sb.]

@@MahsaOmri what do u mean by modified? so 33 bus case, i think, is available in matpower. can u tell me more details on how u plan to modify so i can help you?

[@MahsaOmri]

@@sb.sb.sb. In the modified system, some buses and branches have been removed and a number of DGs have been installed in some buses.

[@sb.sb.sb.]

@@MahsaOmri so status of outage buses and branches can be set. mpc.bus column 2 - when set to 4, it means bus is out. mpc.branch column 11 (I think) when set to 0, means line is out. Check the manual for confirmation. How are u modeling the DG? btw my advisor is from ur university 😉

Donot make a video without any sound.

ami re-upload korbo eta. using matpower is pretty simple though
