Hi, I am wondering if there is any python code/function availble to parse out glm file and find out all down stream and upstream sections in a glm file? My thought: convert glm to feeder tree Convert feeder tree to networkx graph and then work on networkx graph?? any better idea or any already written piece of code. Thanks, Pedram

Hi: Is tehre anyway to replace one year (tmyfile) with multi year actual wethaer for multi year simulation in climate object? I mean if my wether file have the complete timestamp (including year) like below Buffalo ,NY weather file ,,,,,, $state_name=NewYork,,,,,, $city_name=Buffalo,,,,,, $lat_deg=42,,,,,, $lat_min=13,,,,,, $long_deg=-71,,,,,, $long_min=56,,,,,, temperature,wind_speed,humidity,solar_dir,solar_diff,solar_global, year:month:day:hour:minute:second,,,,,, 2016:01:01 00:00:00,30.92,12.74,75,0.00,0.00,0.00...

Frank: Thanks for the KLU suggestion, it made the simulations much faster. Pedram
-
I am trying KLU solver as Frank recomended, and it showes much faster speed that superLU, I will post the results later here. Thanks, Pedram

Yes, one of them is swing bus.

I have a ctually another feeder simulation using method 2 (explained above) that took almost 3 days, if you look at results 96% of the time is for the meter object, I have 541 meters in this glm. Core profiler results Total objects 4807 objects Parallelism 1 thread Total time 261387.0 seconds Core time 1912.2 seconds (0.7%) Compiler 6.6 seconds (0.0%) Instances 0.0 seconds (0.0%) Random variables 0.0 seconds (0.0%) Schedules 0.0 seconds (0.0%) Loadshapes 0.0 seconds (0.0%) Enduses 0.0 seconds (0.0%)...

Hi: Anyone has any comment/suggestion for my post above? Thank you, Pedram

Hi: I'd like to get your idea on how to increase simulation speed on my simulations and I want to share two glm runs for same feeder (differnt modelling on loads) model 1) Loads are modeled as same feeder shape file (coming as one hourly player in a glm file) multiplied by a mulutiplier. model 2) every single load is modeled as a table in mysql and reads from there Runs are for 2189 days and minumum time step is 1 hour. All recorders, collectors, players, weather data and loads have 1 hour interval....

I have a lot of mysql.players in my glms for every single customer, and I don’t add any query into my mysql.player and I use default query. I noticed there is no difference on initialization time of my feeder simulation regardless of stop time of simulation (1 day to 1 year takes the same long time). I thought default query is selecting data between start and stop. I looked at player.cpp and on line 130, I found this in player.cpp data = db->select("SELECT t,%s FROM %s WHERE t>=from_unixtime(%llu)...

Windows platform (GLD built by msys, MinGW). What is this error exactly?

Hi: I am getting this error on the new build of GridLAB-D, it doesn't stop the simulation and it runs and apparently work well. What is this error? Pedram
-
Hi: I am using mysql players in my glm, in the older verrsion of GLD, Daylight saving didn't work. so we put the the data in database without considering Day light saving and it was working very well for running a full year simulation. Now that I have switched to the new version of GLD I get error when it gets to the day light saving day and simulation stoppes. Is there anyway that I can turn off dayligh saving consideration in simulation? Thanks, Pedram

Hi: My effort on building through Cygwin was failed. I was able to to successfully install GridLAB and create exe files and all necessarry foldres...but appraently it acts as Linux release and it can not find windows path. So I moved back to MinGW. there is seriouse error on Sourceforge installing MinGW through 'mingw-get-setup', because it can't download necessarry .lzma files. I was able to write an script and download all necessarry lzma files (114+65) and then copy them in 'C:\MinGW\var\cache\mingw-get\packages',...
-
Is it possible to copy all required files in the same folder as .exe file and some how change config file, the we will have just one path!?
-
Dave: Thanks for the message. Can you please tell where I should add prefix? I didn't get the second suggestion, can you explain. My H drive is just disk that totally mapped as a volume. I also did this test hat copied entire folder of intsallation to drive C and changed all requied path and still getting thi error. Pedram
-
Here is also you can download the entire folder of GridLAB-D and installation https://s3.amazonaws.com/gridlabd-built/gridlab-d.7z and here is just GridLAB build https://s3.amazonaws.com/gridlabd-built/gridlabd_install.7z using Cygwin, I wan to make sure there is no probmlem on build and it is just PATH issue Thanks, Pedram

I should add I checked and I have tzinfo.txt in 'H:/GLD_sept_2017/gridlab-d/gridlabd_install/share/gridlabd' but somehow it can't find it!

Frank: Sorry for confusing you with a lot of posting. Here is the status of my build with Cygwin now. I was able to build GLD with below codes in Cygwin cd /cygdrive/h/GLD_sept_2017/gridlab-d/ autoreconf -if ./configure --prefix=$PWD/gridlabd_install --enable-silent-rules 'CFLAGS=-g -O0 -w' 'CXXFLAGS=-g -O0 -w' 'LDFLAGS=-g -O0 -w' make make install Still I get this error: UNHANDLED EXCEPTION: timezone specification file tzinfo.txt not found in GLPATH= H:/GLD_sept_2017/gridlab-d/gridlabd_install/share/gridlabd;H:/GLD_sept_2017/grid...

sorry for long message but I found another thing regarding building xerces, I get below error Administrator@WIN-VL4ECSKRQ7A /cygdrive/h/GLD_sept_2017/gridlab-d/third_party/xerces-c-3.1.1 $ ./configure --build=x86_64-w64-mingw32 --prefix=/opt/windows_64/mingw checking build system type... x86_64-w64-mingw32 checking host system type... x86_64-w64-mingw32 checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p......

in addition to my last post I would like to add that I am able to build with codes below (through cygwin): the difference is that I don't specify '--with-xerces=/opt/windows_64/mingw ' in configure/ autoreconf -if ./configure --prefix=$PWD/gridlabd_install --build=x86_64-w64-mingw32 --enable-silent-rules 'CFLAGS=-g -O0 -w' 'CXXFLAGS=-g -O0 -w' 'LDFLAGS=-g -O0 -w' make make install in this way xercesc is found in after configure (from Cygwin libraries, see attached photo) but after I build gridlabd...

Hi: I have some feeders that I have convergence issues for some periods that means when I put simulation for run (for example for 5 month) I get 'convergence iteration limit' errors after some days and simulation stopps. I want to see where I should look for this to solve? This is my thought: 1) since the simulation can be done for couple of hours we don't have any prolem in the network like islanded area, parallel lines,.... Correct? 2) The only reason for this convergence could be the loads on...

Hi Frank: Thanks for the advice. I will defenitely apply. I also need to find a way to build GLD. I have seriouse problem using mingw-get-setup.exe to install MinGW, it doesn't work, I have posted on their forum so far no response. In the mean while I was thinking if it is possible to install GLD using Cygwin. I am wondering if we can replace using MinGW by Cygwin, if so what would be in teh additional steps I should take? Pedram
-
Frank: Thanks for the explanation. I need to manually build it the source codes because I added some lines into the link.cpp and others to record Zthev but because of MinGW error, I am not able to do it now. What I did, I instaled 4.0 version from sourceforge and added the 'strictly_radial false' line to fault check and now I am getting convergene error.

Actually I just noticed I have 'cap_nominal_voltage' in my cap model as well defined as L-L voltage and nominal_voltage as L-N (like all other nodes).

Hi: I just want to confirm voltage_set_low ( or voltage_set_high) in VOLT control Cap banks are L-L voltages? (nominal voltage of the cap and other nodes defined as L-N voltage) Thanks, Pedram

Hi Frank. Thanks. This is exactly what I was looking for.

Hi: I have a basic question and I want to confirm with you. My question is incorporating equivalent source impednace upstream of each feeder into the feeder model. Is it safe to add source impedance of the feeder to the substation transformer impedance in each feeder model? If not what would be a better alternative? Thanks, Pedram
