Hi GridLAB-D Team, GridLAB-D version: GridLAB-D 5.3.0-20236 (e1841e1e:master) 64-bit LINUX RELEASE HELICS version: 3.6.1 (2025-02-24) I’m currently integrating GridLAB-D with HELICS and working with inverter objects in CONSTANT_PQ mode. I wish to change P_Out and Q_Out in real time, which is why I am using HELICS. Anyways, I am trying to change the P_Out value during the simulation. I can see the values being read by Python and published by the python federate. However, the output file from the recorder...

Great. Thank you, Tom!

Hi Tom, Thank you for your detailed response. Out of curiosity, I'd like to try the older version of OpenDSS with my current application. Where can I find an Ubuntu-compatible opendsscmd version? Preferably 1.2.11. Thank you.

Hello All, I'm trying to export UUIDs for a DSS file. However, as the title says, all the exported UUIDs are not prepended with an underscore "_". The command I'm using is Export Uuids Is there an older version of opendss that exports UUIDs with an underscore prepended to each UUID? I'm using opendsscmd on ubuntu, version 1.7.4. Thanks in advance.

Hello All, I'm having some troubles installing GLD and HELICS. The installation process went fine for both of them. However, when installing GLD with HELICS, the checking for helics flag is no. Here's some info about the system: GridLAB-D 4.3.0-18923 (Navajo [107009aa:develop:Mod]) 64-bit LINUX RELEASE import helics helics.helicsGetVersion() 3.1.1 (2021-12-14) OS: Ubuntu 20.04 Since I'm installing both helics and GLD on a VM, I went with TESP as shown in this link. Both GLD and HELICS are installed...

Hello Frank and Jason, Thank you for your reply. I've been working on waterheater.cpp file. I'll create a pull request once I get it fixed. Thank you again.

Hello Scott, I used this discussion on github that helped me install gridlab-d v4.3. Click here! Hope that helps. Midrar

Frank and Json, Thank you for taking the time and look into this. I did modify the heating element capacity to 0.6 kw but still the water temperature goes way above the setpoints. Another point that brought my attention is the waterheater_model property. My understanding of the waterheater behavior is that it switches to twonode behavior when there's sufficient water_demand. In the HPWH case, it switches to twonode behavior regardless if there is a water_demand or not. Here's EWH output file: # timestamp,height,tank_setpoint,waterheater_model,power.real,constant_power,constant_current,water_demand,temperature,is_waterheater_on...

Hello Frank, I hope all is well. Is it possible to get a copy of the document where the HEAT_PUMP water heater was tested? Thank you

Hello All, I'm working on modeling heat pump water heater. I noticed a weird behavior. The water heater does not stick to the setpoints. Once I change heat_mode ELECTRIC, the water heater behaves normally. Have the gridlab-d team had a chance to test it? Are there any test glm files that I can look at while modeling the HPWH? Thanks

Hello Frank, Thank you for your response. I made some changes to the commands in the above links. The way I installed helics is: cmake -DCMAKE_INSTALL_PREFIX="/Users/$USER/local/helics-gcc-2.6.1/" -DBOOST_ROOT="/Users/$USER/local/boost-gcc-1.69.0" -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -DZMQ_USE_STATIC_LIBRARY=ON -DUSE_BOOST_STATIC_LIBS=ON -DCMAKE_EXE_LINKER_FLAGS="-Bstatic" ../ The output is the following: -- SYSTEM INFO -> Unix Makefiles Darwin-20.2.0:GNU-10.2.0...

Hi Frank, Im a bit concerned when you say it works fine in FBS with the switch, but not NR. It is failing for the same reason in both solvers for me, which it should. I went over the glm file with FBS solver. It didn't have impedance_dump object in it. The glm file with FBS solver ran without any errors but the water heater didn't respond at all to the switch state. After reading your response, I understand the reason behind the waterheater behavior. In terms of the overall behavior you are trying...

UPDATE: References: http://www.pnl.gov/main/publications/external/technical_reports/PNNL-17694.pdf http://gridlabd.sourceforge.net/wiki/index.php/Market_User_Guide#Passive_Controller_Object Following the second link, I used passive controller to turn ON/OFF the water heater. It's behaving as expected. Regarding the first post, I still can't figure out why the water heater wouldn't behave well with switch object. Any help would be appreciated.

The water temperature did not seem to follow the scheduled setpoints of...

Hello All, I'm working on a long project that starts with creating waterheater usage profile in GridLAB-D. In this link http://gridlab-d.shoutwiki.com/wiki/Spec:Residential#Default_Waterheater, I noticed that default water-heater settings don't include water demand profile. I tried "residential_waterheater.glm" file in github repository and it worked well, but my question is: 1)- Is there a water_demand profile that I can use to test water_heater object based on water demand? Thank you.

Frank, I was thinking maybe I could toggle the switch status using player object. I'm not sure if players are able to read csv files or .player files with strings. I attached an example of the glm file and player files as well. In the attached files, the switches are always in CLOSED state even though switch2.player file has OPEN state in it. I wonder why that is. Is it simply because players don't understand strings?

Thank you for your reply, Frank.

Hello Everyone, I hope all is well and safe. I'm trying to control two loads in Gridlab-d under the following condition, if one load is ON, the other one must immediately turn OFF. I looked at the wiki and found multiple objects to control loads such as schedule loads, transactive controls, and passive controls. However, non of these features lead to my goal. Any help would be appreciated. Thanks

Thank you so much Frank!

Hello there, Hope you're all safe and well out there. I'm using IEEE-4-node feeder glm file and attached a load to node 3.When I run the file, I get this error "expected ';' at end of property specification". I checked each line and no ';' is missing. could somebody recommend other ideas? here is the output I'm getting: May_28_IEEE_Node_4_Feeder.glm(201): expected ';' at end of property specification May_28_IEEE_Node_4_Feeder.glm(198): load failed at or near 'object tripl...'
