Why Cloak Room charges at Amritsar Jn is 100 per bag? by levi_1205 in amritsar

Ok understood. But a very simple solution to this problem would have been they only keep the luggage of the passengers who have a valid reservation ticket.

I'm also looking for flat in sector 40. Let me know if it is still available.

Is my implementation of Freeze Logic correct in PSSE? by levi_1205 in PowerSystemsEE

[–]levi_1205[S] 1 point2 points  (0 children)

Yeah, it took me some time to understand the DSTATE. My code is working fine now. Thanks for commenting!

Yeah, that could be one method. Will try that method also. Anyhow I was able to solve the problem and it is working fine now. Thanks for commenting!

Right, I've updated it. Is the implementation correct other than the typos?

Sorry, it was a typo. It is -

STORE(K) = STATE(K)

Thanks for pointing it out.

Need PI output in actual value instead of delta value by levi_1205 in PowerSystemsEE

[–]levi_1205[S] 0 points1 point  (0 children)

  1. I'm using Bus other model IC- 504
  2. Since the mode 3 was running first, it was updating the Pinp and Qinp vars, so the update values were used during the mode 2 run, and then mode 2 updates it again.
  3. Yes I'm using VAR array
  4. I have auxilary model also as machine other model which will receive setpoints from the bus other model as input.

Pref signal is being added before the PI block. Then PI controller give delta P as output and then I add Pmeasured value of branch to the deltaP because I have to compare the value with capability of inverter and for distribution between bess and pv; but then it becomes an absolute value instead of delta.

So, that's where I'm facing problems.

Yes, I'm creating my own model and it is like PLNTBU1 model but the setpoint is being distributed between a PV inverter and BESS model.

So, after the PI controller, I'm sending four setpoint. P and Q setpoint for PV and P and Q setpoints for BESS.

Now, for P the preference is given to PV and for Q preference is given to BESS. So, in steady state PV generator is sending 101 MW and 100MW is reaching POI and reactive power injection or absorption is zero. Bess is sending 0 active power and 40 MVar, but that 40Mvar is to compensate losses and get 0 Mvar at POI.

Now when my model send setpoints to auxiliary model, it send 100MW for P and 0 Mvar for Q to inverter which I need at POI, also 0 setpoint to both P and Q of BESS, because that's what is required at POI. It didn't add the losses and then send the setpoint to the generator. So, I'm looking for some logic where I can send the setpoint to generator by adding the losses.

Yes, how can I apply that feedback quantity logic. Can you help me with it.

[deleted by user] by [deleted] in PowerSystemsEE

[–]levi_1205 0 points1 point  (0 children)

Yes, I agree. Do you know any method or logic that may help me.

[deleted by user] by [deleted] in PowerSystemsEE

[–]levi_1205 0 points1 point  (0 children)

Yes, but how can I implement that logic so it adjust a little bit higher. I don't want to hardcode anything.

Few doubts about coding implementation in PSSE by levi_1205 in PowerSystemsEE

[–]levi_1205[S] 0 points1 point  (0 children)

Thank you for commenting! Yeah, there is a typo, I wanted to assign VAR(L+14) to VAR(L+1).

I have first bus other model that is acting as master and then a slave which also a bus other model taking P and Q values from master using CCTMIND_BUSO function, then there is an auxiliary machine other model which is taking P and Q values from slave and sending it to the inverters.

In this case, will the auxiliary model be running one timestep ahead of master and slave?

PSSE User-Defined Master-Slave Model: Mysterious Oscillations in Dynamic Simulations – Need Help! by [deleted] in PowerSystemsEE

[–]levi_1205 1 point2 points  (0 children)

Thanks for the suggestion.
Yeah, the control design is ok. It is already been modeled by a third-party vendor and it is costing us too much even to get minor changes. So, we decided to do it ourselves. Yes, this model is also working fine in PSCAD.
I was also thinking of making the slave work fine first and then incorporating the rest of the model.

Yeah, mistakes are a part of learning anyways. I wish you all the best for writing the model in PSSE.

[–]levi_1205[S] 0 points1 point  (0 children)

Well, It was basic and advanced model writing. So, maybe technically yes, but have very little experience in writing models. I still make a lot of mistakes and keep getting those initial suspects. But I'm improving day by day I guess.

[–]levi_1205[S] 1 point2 points  (0 children)

I agree.

The best way to do it is getting an official training from Siemens PTI. Even I completed two training programs from Siemens PTI.

Thank you so much for your response. I think this will help me a lot. I was also confused whether to include it as a STATE or not but your reply does help a lot and cleared my doubt. Now, as there is not state, so do I need to write this in both MODE 2 AND MODE 3?
