Yes I agree, it's not directly load flow tutorial. But it is certainly a fundamental concept that must be understood before (direct) load flow concepts are considered
We appreciate your query. Shunt admittance is actually the reciprocal of impedance expressed mathematically as Y=1/Z. If you already know the line impedance then you can easily calculate the shunt admittance by using the above formula. However, if you need Admittance matrix, then you need other parameters too.
If you only know the line impedance, you can calculate the line admittance. But, this is not enough to calculate the shunt admittance, as there is no formal relationship between line and shunt (there are many physical factors envolved). It must be given this information, as a line characteristic.
Glad to hear that. We have always hoped to share our knowledge in a way easily understandable by all. Words of appreciation from you and people around the world are the things that drive us to give back more. We really need your support though, so that we may continue providing you value! How about you support us and become our patron? Please visit patreon.com/generalpac . Awaiting to greet you as a patron.
In Power System Analysis course we will start from very basics: principles of Balanced systems, how power factor affects the performance of systems and techniques which we can employ to improve the power factor. In addition, you will build a strong concept on per unit systems and load flow analysis. This module consists of four parts, each building upon your knowledge based on previous ones.

+priya raghuraman There should be no load connected to the slack bus. That's one of the rules of the Slack bus. Also, the Ybus matrix only consists of transmission network. We must include the admittance of the transmission line. And if it's medium length or larger, then account for the shunt capacitance as well. The LOAD is accounted for in the power-flow equations. The power at a particular bus is equal to the power generated at that bus MINUS the load at that bus. or Pi,scheduled = Pi,generated - Pi,load-demand --- I hope this makes sense.
If there is a physical connections between node 1 and node 4, then yes -- there should be an impedance. But if there is no physical connection (i.e. a transmission line) then there would be no impedance.
Hello Khollis Tianii, The 'j' operator is used in engineering denotes the complex number operation if it is attached with any number. It can be simply considered as a basic imaginary number 'i' iota which is equal to the sqrt(-1) . In electrical circuits +j shows that a phase advance of 90 degrees and -j shows the phase retard of 90 degrees. We can simply convert 1/j0.4 to -j2.5 by using the basic imaginary number laws and operation: We know that: j x j =j^2 = sqrt(-1) x sqrt(-1) = -1 Therefore, if we rationalize the denominator, then: 1/j0.4 = 1/j0.4 x j/j = j/ 0.4j^2 We know that j^2 = -1, hence: j/ 0.4j^2 = j/-0.4 = -j2.5 Thanks, hope this might be helpful!

good background music, not very intuitive tutorial though, watch Brian Douglas from Control System Lectures (UA-cam) and learn something about REAL intuition.
Having the "stage directions" read out was quite annoying and distracting. If you see fit to rearrange elements, just do so, don't tell me you're doing it like it's something important or relevant to the subject.

how can I support? I really enjoy your tutorials! I so much appreciate your time and effort. THANK YOU!
This is a very well done tutorial and thank you for all your other tutorial videos!
+Jeffie Matsushime Thanks for the comment! If you have any questions, please do ask at our Q/A forum; gpac.link/1QZu0pt
Awesome!!! That is clear than what my college teacher said!!! Thanks~~~
undoubtedly, the best area to refresh ones power system concepts.

great illustration thank you
Welcome 😊
can u plz upload a video for unsymmetrical faults
This is good but I want you to do some tutorial about Load flow...
Yes I agree, it's not directly load flow tutorial. But it is certainly a fundamental concept that must be understood before (direct) load flow concepts are considered
Can you explain to me, how to calculate admittance shunt if we just know the value of the line impedance?
We appreciate your query. Shunt admittance is actually the reciprocal of impedance expressed mathematically as Y=1/Z. If you already know the line impedance then you can easily calculate the shunt admittance by using the above formula.
However, if you need Admittance matrix, then you need other parameters too.

HI.. what is the application program you working on?
Hi, Great video. What drawing tool are you using for your video?
You made it easy to understand 😩
Hey Solimon, Thank you for your feedback. We are glad you liked our videos :)
thanks for this video but my quation where we use Ybus and what is befit for study it
Hi Anwer. The Ybus matrix is a critical tool that we use to calculate Power Flow in the power system.
+GeneralPAC: Power System Tutorials thanks so much now its clear mean in next subject we will use it

Have a look for y bus ua-cam.com/video/5OTDYDGxL2E/v-deo.html
thank you
Does the load connected to any bus (slack bus included) make any difference to the Ybus matrix?
+priya raghuraman There should be no load connected to the slack bus. That's one of the rules of the Slack bus. Also, the Ybus matrix only consists of transmission network. We must include the admittance of the transmission line. And if it's medium length or larger, then account for the shunt capacitance as well. The LOAD is accounted for in the power-flow equations.

what is ieee standard 30 bus system and ieee standard 118 bus system.
please do more
In a fourth order matrix , why an impedance is not connected between nodes 1 and 4 . (assuming generators at all four nodes) ?
If there is a physical connections between node 1 and node 4, then yes -- there should be an impedance. But if there is no physical connection (i.e. a transmission line) then there would be no impedance.

How to calculate 1/j0.4 become to -j2.5?
Hello Khollis Tianii,
The 'j' operator is used in engineering denotes the complex number operation if it is attached with any number. It can be simply considered as a basic imaginary number 'i' iota which is equal to the sqrt(-1) . In electrical circuits +j shows that a phase advance of 90 degrees and -j shows the phase retard of 90 degrees.
We can simply convert 1/j0.4 to -j2.5 by using the basic imaginary number laws and operation:
We know that:
j x j =j^2 = sqrt(-1) x sqrt(-1) = -1
Therefore, if we rationalize the denominator, then:
1/j0.4 = 1/j0.4 x j/j = j/ 0.4j^2
We know that j^2 = -1, hence:
j/ 0.4j^2 = j/-0.4 = -j2.5

+Nirbhay Thacker will do. Thanks!
sorry if that was a bit mean, I just meant we could all have better knowledge if the details were discussed.

Nice vid but you could exclude drawing parts and just skip to calculation.
Having the "stage directions" read out was quite annoying and distracting. If you see fit to rearrange elements, just do so, don't tell me you're doing it like it's something important or relevant to the subject.
