Hello Abdullah, Apologies for the delay in responding. The old population script located under the taxonomy_feeders repository should still work, but you do have to modify the IEEE feeders (because the script is looking for triplex_meter and triplex_node objects). There is an IEEE 8500-node version located under the tools repository -- I don't know if that still works though. There is an updated population script associated with the GridAPPS-D project a version can be found here, but I don't know...

Hello Abdullah, Since this is basically the same as your other question located here, please see that message. -Frank

Hi, I am wondering if there is any repository which has IEEE test feeders models with houses? For example IEEE-13, 123 etc. Or, if there is any updated script which will populate any IEEE test case system with houses? This would be really help.

Hello Adbullah, Based on the type of data Jerry included in the original email, my guess would be a load object was used load wiki page. That type of CSV could probably be just "played" into the base_power_X fields (you may need to divide it by 3 and set for each of the three phases). That would allow you to set specific ZIP fractions/power factors too, if there's a specific type of load you are emulating. -Frank

Hi Jerry, It would be really helpful if you could share the solution in details here. I am new to GridLAB-D. Thank you.

Hello, Sorry for creating a new thread, but I want to confirm something. For context I want to make a zero emission building using renewable specifically solar. I want to simulate the electrical demand of my school using a player. Is there some sort of object load that can do that or has that property? or is object house the only way to simulate that? I attached a csv of my school electrical demand for reference. I use the latest version GridLAB-D 5.2.0-19642

Hi Frank, Thank you for clarifying! I will surely look into the Arras Energy fork.

Hello Swastik, Those values are arbitrary, set to be "high" as to not trigger warnings when people aren't concerned about them. So the calculation was "that looks like a nice big, round number - good enough!". I'll also note that the functionality is quite limited, mostly with them throwing a warning of "line is overloaded" (but I believe the violation_recorder looks for overloads). As you mentioned, that 4.16 MVA (actually closer to 12.48 MVA, since that is a per-phase check) is quite high. Reaching...

Hi, I know that we can set the thermal limits on the lines using: rating.summer.continuous; rating.summer.emergency; rating.winter.continuous; rating.winter.emergency; But i was wondering how is the gridlabd assuming the limits to be 1000A for summer and 2000A for winters by default. Is there some calculation on the basis of which GLD comes up with this? Also, it would be highly helpful if someone could tell how to reach at these limits? Let's say for my system with 4.16kV base voltage won't 1000A...

Hi Team, I have been working with GLD (Version 5.1) for quite some time, familiarizing myself with it. I recently started tweaking around to see the internal working of it. Currently, I am working with the IEEE 123 Bus system, where I am attempting to add a few large loads to observe warnings related to overloads and voltage issues. I have tried everything to trigger warnings by setting "warning_undervoltage 0.95; warning_overvoltage 1.05;" in the powerflow module and using a violation_recorder,...

Hello Abdullah, Since the post is over 5 years old, I'd be surprised if Cody responds. There are some feeder generators/population scripts under the GridLAB-D Git repository, or there's one part of the Transactive Energy Systems Project (specifically located here) that people have had luck with in the past (and is much newer than the scripts in the GridLAB-D repository). -Frank

Hello Loraine, Unfortunately, we deprecated the MATLAB functionality a couple versions ago (v5.0 or v5.1 silently stopped including it). The preferred approach at the moment is to use the HELICS cosimulation platform as the communication method between GridLAB-D and MATLAB (among other things). Due to how the MATLAB API kept changing and some of the limitations of our existing implementation, HELICS probably provides the most capability to interface with MATLAB at the moment. -Frank

Loraine modified a comment on discussion Help/Technical support
Thanks, Andy, for your answer. I was able to install GridLAB-D succesfully on Linux . I have the following question: Is Matlab-link functionality still available in this version? If so, what are the variables that I should use at build generation?

Hello Jerry, Apologies for the delay in the response. "Probably". It depends what format your load profile is in. The obvious choice is usually as some sort of player object, where you use that to push the data to a powerflow load object. If you haven't done so, you may want to check out the webinar recordings we have, or the GridLAB-D Tutorial to get some ideas on how that could be incorporated into the system. Depending on the data, you may also be able to do it via the MySQL interface or using...

Hello Mamun, Apologies for the delay in getting back to you on this. Technically, it is possible to run GridLAB-D in Python, but only by manually calling the executable (with something like popen or similar). There's a simple example up on the GitHub tools repository. For HELICS, if you download the compiled executable for GridLAB-D, you'll need the complimentary compiled binaries for HELICS. Since you're using Python, you'll want to consult the HELICS repository and forums/tickets for the most up...

Hello Jerry, That is correct. power convention in GridLAB-D is represented from the load's perspective. Power Generation from a PV/Battery would be a negative load. Andy

Hello, I am a beginner, so I have been playing around with some code. I am working on a project which requires me to add a PV to the IEEE 13 bus. My goal is to get the power output of the PV. The recorder is giving me a negative power. What am I missing? GridLAB-D 5.2.0-19642

Hi Dr. Tuffner, Thank you for your valuable reply and specially guiding me to the tutorial pages. Yes, you are correct. I had multiple versions of GridLAB-D installed. I have fixed the issue. Currently, I am using GridLAB-D in my ubuntu via Oracle VM Virtual Box and it is working fine. I can run the glm models now. Also thank you for pointing out about the windows installer. I don't know why I missed it but it is definitely a great alternative for me. In future, any problem arises, I would definitely...

Hello Mamun, Apologies for the delay getting back to you. The YouTube sequence linked (it was in a message you deleted) is a set done by a third-party that was posted to YouTube - it wasn't an official GridLAB-D tutorial, so that may be why it has some oddities in it. We highly recommend users visit the official wiki, especially the GridLAB-D tutorial page. First off, that error looks like you have multiple versions of GridLAB-D installed. Since you mentioned a Debian install in WSL, I'm guessing...

Hello Lucas, The ELCAP information should be based on this document, with many references here. I'm not sure if the raw data is available anywhere. One item for your GLMs is you do have a ZIP refrigerator in both of them, so that may increase the likelihood of "always having a load". That said, if you look at the REFRIGERATOR schedule (and the implicit versions are similar), it never has a zero value. Since this is just effectively doing a power manipulation (and not cycling the compressor or anything),...
-
Hello Hussain, Apologies for the delay in responding. The answer is probably "sort of". You can play a voltage player in that has varying frequency, which powerflow and generator components would then respond to. An example of this (and the code to generate it) is located in the tools->matlab_scripts repository. You can look at that code as a way to figure out how to impose the frequency adjustment you've mentioned into a voltage player. This would allow any generator on the system to respond to...

I am using GridlabD version 5.1.0. I need to accurately simulate the load profiles of various Household appliances (dishwasher, refrigerator, etc.) and have been trying to do so unsuccessfully via GridlabD . To my understanding, there are 3 ways to incorporate appliances into a GLM file (Implicit Loads, Zip Loads, and Unsupported Appliance Models). I attached two GLM files with my attempts for utilizing Implicit Loads and Zip Loads to do this. I got the Zip Load parameters and schedule from one of...

Hello, I'm a new GridLAB-D user. I have a set of time-series frequency data with a 0.033 second time resolution. I'm curious to know if it's possible for me to use this data within a player object as an input for a generator model in GridLAB-D. Thanks in advance.

Excellent! This worked perfectly! Thanks for your help! Lucas

Hello Lucas, You were pretty close with your attempt, but a few things needed to be fixed. The first is I specified a timezone entry in the clock portion of your GLM. Some GridLAB-D models can do some unexpected behaviors if you don't define this, so I always recommend people include it. I set it to CST/CDT, since that's where weather file being used was based. I also extended it to 5 seconds of runtime, just so it shows a transition in and out of deltamode. The second item is the player file. You...

Hello Lucas, Even with an "empty house", it still technically has a default version of the HVAC enabled. That's why you were seeing the spikes up to 5200 W. If you recorded the air_temperature value, you'd likely see it reach a set point, turn the HVAC on, then turn it off. If you want a truly "idle/empty" house, you can set your house like this: object house { parent house_meter; system_type NONE; heating_system_type NONE; cooling_system_type NONE; auxiliary_system_type NONE; fan_type NONE; } GridLAB-D...

Hello Elizabeth, Can you provide a link (or post) the IEEE 4-bus network file you're using? It sounds like there's a syntax error, but it is hard to tell what exactly is going on with that output. I do not think it is due to any missing libraries or anything like that - it looks like it is trying to run (so that's a good start!). If you can post a link to the video, that may be helpful too (just in case we have a mistake in it). I usually refer people to the GridLAB-D tutorial (and its files located...

Update: I attempted the above as best as I could. Here are the glm files. I added an Ev charger and Ev charger_det, but still no sub-second values are recorded. Any idea of where I'm going wrong?

Hi Andy! Thanks for your response! I am still slightly confused on how to implement a sub-second player. Based on the documentation, I take it I add a player object to my GLM file and then also use a CSV file like the one I have attached below (with seconds to 6 decimal point precision). Am I understanding your feedback correctly? Also, since there are limited dynamic models for the residential model do you have any suggestions of other appliances or machinery from other modules that I might be able...

Using Gridlabd V 5.1.0 I am trying to simulate and record the power consumption of a home throughout the course of one day. The supplied GLM file features a recorder, an empty house with no parameters. I expected the recorded power output for this file to be 0 at all times, which was the case until I added the climate module. Somehow this affects the house's power draw so that it 0 at some times and around 5,200 watts at others. I have attached the output csv file. I am wondering: why does adding...

Hello Adel, Can you point toward the exact HELICS example you are trying to run (GitHub path or relative file structure path)? That will make sure we are looking at the right example and can test/verify if it still works. You mentioned you are using the executable install - for clarification, is that the version located here? -Frank
-
Hello THASNI, Unfortunately, not directly. Due to how it is implemented, GridLAB-D is expecting one fundamental frequency for the analysis, as written (so you can have fluctuations around 60 or 50 Hz, but the equations are expecting the whole system to be around that point). To do hybrid, you'd technically need two -- I'll also caveat that theoretically GridLAB-D could be set up to DC analysis, but it isn't something we've messed with much. There is some ongoing work to define a DC bus structure,...

Hello Lucas, The reason you don't get any subsecond data from the recorder is you don't have any object that triggers the simulation to enter deltamode. The common and easy way to do this is to provide a player object that plays a value at a subsecond timestamp to an inconsequential object's property. Unfortunately, besides the ev_charger object there are no dynamic models for any of the enduse load objects in the residential module at this time. The inclusion of such models is uncertain at this...

Hi Frank, Sorry to bother you again.

I copy the fault you have to the IEEE 13 bus default model and it run well. Can you please help me on the KLU solver issue? I am using windows system to run that model. Thanks. Best, Corey

Dear David and Frank, Thanks for your help. The model helps a lot. Moreover, I want to know how to change my load during the simulation—for example, changing the load by inputting the load profile of a day so we can simulate a whole set of distribution data depending on different times of the day. Thanks. Best, Corey
-
Hello Corey, Based on your description, GridLAB-D does have all of the capabilities you need. With that said, our fault analysis capability is evolving at the moment. There is some base functionality in the code, but it requires you to manually induce faults (by basically applying an appropriate small impedance load at the fault location). We're working to generalize it to the existing "fault" architecture in GridLAB-D. That way, you could use the eventgen object that some of the prior fault topics/classes...

David P. Chassin posted a comment on discussion Help/Technical support
Hi Corey, My preferred way of starting a new project is to find test-cases in the corresponding module's autotest folder that validate the capabilities I need. This is by far the most comprehensive and authoritative source of examples for how to use the more esoteric features of GridLAB-D. The test names are usually self-explanatory. All validation tests start with test_ followed by the test name and the extension .glm. My guess is you are looking for tests that include the terms fault and deltamode....

If my tasks can be done, can anyone send me some examples that we can have a look on them to figure how it is done? Thank you.

Hi everyone, We are endeavoring to utilize GridLAB-D for the dynamic simulation of distribution systems. Our focus lies on the IEEE 123, IEEE 69, and IEEE 13 bus distribution systems. Initially, our objective is to employ GridLAB-D for the simulation of a day-long, or even longer, time period of the distribution system. We are particularly interested in observing the dynamic behaviors as the load varies during different periods of the day. Moreover, we noted from an inquiry in a 2020 forum that there...

In this simulation, a microgrid will be isolated by tripping a switch through the eventgen object. We want to use HELICS to inject the tripping command into GridLAB-D externally. However, we always got the same error message (please see the simulation report below) when following the user guide of the Eventgen external event mode. It seems like...
-
Hello again Valerian, Given the timeline for this fix (might be a couple months), you do have a couple alternatives. One is to keep using an older version of GridLAB-D (assuming you don't need any of the new features). There's also a fork of GridLAB-D that is up over at Linux Foundation Energy, Arras Energy. Server mode may still work on that fork, again assuming you don't need some of the capabilities from GridLAB-D 5.0/5.1. -Frank

Hello Sayeb, Apologies for the delay in responding to this. You should be able to put a capacitor on the loads (just parent it to it) - if that doesn't work, it may be a bug. Your syntax looks correct. I only have a couple potential ideas on why it may not work. The first is if the dwell_time, delay_time or capacitor_delay delays might be longer than the changes in your system. So if things change too fast and the power factor "goes back within compliance", it will reset and not switch. The second...
-
Hello Valerian, That is definitely not a desired behavior and I am able to replicate it. Unfortunately, I don't see any obvious cause for it, so there's no quick fix for it. I'll file a ticket for it, but I'm not sure how quickly we may get this fixed. Link to issue -Frank

Hello Barsha, Again, apologies for the delay in responding. Does this mean you resolved the issue (and it was just the PATH inclusion), or are you still having problems getting GridLAB-D to recognize the connection module? -Frank

Hello Barsha, Apologies for the delay in responding. In the load object, the constant_power_A..C variables (along with constant_current_ and constant_impedance_ prefixes) will post that load to the powerflow at every step, with their impact being affected by or affecting the voltage on the system. From your earlier model, as long as the load object is connected downstream of the metering device (because they measure flow through them), it should register. So I think your understanding in the first...

It's a way for the meters to calculate the monthly bill for customers participating in wholesale market transactive control schemes.

Hello Team, I am grateful to have you here to solve many of the issues I am facing. It has been a great help. At the moment, I am trying to look deeper into the billing modes and pricing. I want to understand how the simulation works for HOURLY billing modes and how are power_market defined to generate prices. I have been following the wiki but it only gives a brief description. Is there any other documentation that explains how meter, billing and pricing system is integrated in Gridlab-D? I am also...

Yes, I have HELICS installed in the machine, I am assuming it was the helics.dll file that needed to be in the PATH environment. Thank you for the answer and the detailed instruction.

Hello Frank, Thank you for clarifying the question. I appreciate you taking your time to help me understand. At this time, I am providing the glm model with positive_sequence_voltage at the substation and constant_power_A, constant_power_B and constant_power_C in the load object as inputs. My doubt previously was, are these inputs enough for the downstream devices to influence current, power and voltage at a certain timestep in a simulation? - from your answer I can understand that providing current...
