Power System Load Flow Tutorial: Part 1

[@brodyscarlett5527]

This is great information. I've been doing this with etap as an intern, but this explained the back end of why we care.

[@ashk2318]

As an intern at ETAP, what do you do specifically regarding load flow? Also is the work difficulty? Thank you.

[@Ms95656]

Wow that was great explanation. I really appreciate this clear and easy way to understand in simple way how to analyze the system.

Dear C# Tutorials: I'm enjoying your instruction. The graphics and narration are very clear and accessible. In this particular video, there is a digression about which generation units are committed to run and serve load. Please consider revising that section. There are a lot of factors at play: Is it a region where wholesale electricity is traded in a market or is it for a traditional vertically integrated utility that owns and operates everything? You also need to distinguish between energy consumed by load and energy capacity needed to fulfill reliability requirements. Nuclear power definitely is not the least cost source in an era of cheap natural gas and plentiful solar and wind (no fuel costs). The renewable sources also receive incentives for added advantage. Natural gas is flexible to balance out variable renewable supply, but in some regions it must participate in cap and trade. There are also limits on the has pipeline system during winter months. Security, environmental, and legal costs are significant for Nuclear. Until modular nuclear is commercialized (NuScale), nuclear will be considered an inflexible base load source. Aside from the digression into generation sources, I'm loving your instruction. Keep up the great work!

I thought apparent power is P+jQ but you have it as P-jQ Good explanation thank you

[@abhishekparamanand]

It was a very good introductory video on LFA. Thank you. Looking forward to more such videos.

[@yihadhaddad9621]

Magnificent explanation. Thanks a lot.

[@mokhtarawwad6291]

THANKS for the strait forward we explained explanation

[@Omarsayan]

Good explanation, but you need to clear 2 things: 1) The direction of current I(load) and 2) put a star near V2 in the formula, e.g (P-jQ)/conjugate(V2)

[@JohnHondo11997]

I concur with this.

[@maracay20001]

excellent explanation

[@Kaiser.Alexander.I]

Awesome explanation! 👏🏼

[@ryszardcetnarski6648]

Congrats for the quality of schooling

[@TheHaidaman1]

brilliant explained and simple to visualize.

[@rainereyes9027]

Hi.. I just have a question with the 1st equation Iload+ I1 +I4=0.. did you just transposed I1+I4 on the other side? im just wondering why they did not have a negative sign.. and it should be like Iload= - (I1+I4)? thanks

[@jasond2454]

Thank you! This really helps with my course project.

[@auguybakome1127]

Thanks for the detailed explanation. Very helpful

[@user-kn6xf8un7l]

very good explained,thank you so much

[@michaelbee8263]

Great job

[@CH-tv1cy]

Best explanation I've seen

[@richardf9112]

Incredible video. Thanks so much!

[@sajjadkareem608]

Thanks for the great lesson

[@vrbaac1641]

hi.... great subject... ^^ I also want to know, is how can this principle be applied internally to a power system of lets say a a High Rise Building...? thank you very much and hoping for more lessons to come ^^

[@sohailjanjua123]

Hi , I like your lecture. Thanks

[@shara6281]

Great explanation 👌🏻

[@ThePeacefullOasis]

Nicely explained. Couldn't be easier :)

[@erickarwa-0705]

Wonderful video. Great and simple explanation of LFA.

[@eepower]

Great work. Thank you

[@wilmeresuarez]

Excellent....

[@ebarbie5016]

The P-jQ is actually a power conjugate, not just power

[@clemzo6]

It was clear, thank you. I just have one question : When you go through the iteration, how can you be sure that it is not a local maximum ?

[@butterflyseraphine7487]

can i run load flow analysis from a real feeder network

[@Lonkotuma]

Awesome. clean understanding

[@azzammeeralam7182]

For those looking for part 2 here it is. Part 2: kzbin.info/www/bejne/bXLOkquAapJ5h7s

[@Hatem.Egyptian]

thanks

[@blackburnmichelson6189]

this is good but how much time we must guess and itharete this bus voltages ?

[@aramidekay5448]

Why I1 and I4 became positive?

[@harithalau1970]

thank you for pointing that out, i guess he mislooked

[@bluebird9262]

very interesting explanation. I suppose, this is the Gaus-Siedel method.

[@bayaacyril8915]

Great

[@snehamoypatra9786]

MARVELOUS

[@suratkhan2208]

Excellent

[@sarangapinipa720]

wow damn!the best explanation.thank you!

[@robertdavies3384]

What I don't understand is - why does power flow from the generator bus to the load buses with lower voltage? I.e. How can power flow if there is higher potential difference at V1=1.0 to V5=1.03?

[@scc1314]

Hi! For active power flow, it is usually dictated by the angle difference. The bus who leads will deliver the active power. For reactive power, it is usually (for transmission systems with high x/r ratio) dictated by the magnitude. usually the bus with higher voltage will provide the reactive power.

[@kingworld2002]

At 24:30 i think the sign convention is not correction.plz correct me if I'm wrong

[@a13690508319]

you r right

[@adembugra]

Hello teacher, I have a question about the power systems analysis course, can you help me?

[@wesleycostaee]

Fantastic!

[@shakirahnaruyinda3324]

Wana watch the next video

[@donty1994]

thank you so much

[@luisfreire5724]

que manera de explicarlo!!

[@mbagassyaatnuartoro9092]

thanks

[@suongsocheat7553]

Dear Sir. I'm wanna ask u one Q: Could u tell me about the Voltage Regulator definition and useful on the Video? Thank you.

[@theultradiamondgamer7650]

A device which is used to maintain the system voltage with in limits. e.g capacitors are used to maintain the voltage by injecting the vars in system and tap changing T/F are also used to maintain the system voltage.

[@dhafer72]

Hello, do you have e free link to download powerfactory please, I need it for student project ? Thank you

[@thaaralasaday3853]

Is there any vedio about Newton Rufson mothed

[@6996skull]

Hi, has anyone been able to get a copy of the matlab script? Would be really helpful to further understand :)

[@danilodulovic2197]

at 23:12 I think the last equation is not right, check pluses and minuses

[@varghese71]

i agree. plus and minus should be verified for the equations

[@sakirdag2976]

good

[@afaanali4337]

where is the next lecture

[@brucelarge2801]

It's in this series, it looks like Ep #2 models it with C# - kzbin.info/aero/PLGtyXSn57qnLY9uE-7YhiRIY1_aI3e7tl

[@isaactuffuorbiney571]

Great explanation

[@globecity9121]

Excellent
