I have added my dyre file in the answer as I cant add it here as a comment

Hi following is the dyre for 11th bus composite load model used in my simulation

I was working on the dynamic simulation of the IEEE 14 bus system with composite load models at all buses. The IEEE 14 bus test case has a load of 3.5MW on the 11th bus which is less than 5MW. While simulating this case I got a log report stating that "CMLDBLU2 At bus 11 LOAD 1 Ignored because real power= 3.5000 is less than threshold value of 5.00 MW". Is there any way to consider a composite load (CMLDBLU2/CMLDBLDGU2) with a power rating of less than 5MW? If yes, what changes are required to do that? Please help me to solve this situation.

Thank you for your response. I added the real power (MW) and reactive power (MVAR) in "Distributed Gen" values, and the respective mode is set to "ON". Log file doesn't have any errors. I tried to capture the MW and MVAR from DER using the 'VAR' L+121 and L+122, I found these values are zero.

I am working on simulating a test system with CMLDBLDGU2. I realized that the DER model in CMLDBLDGU2 is the same as the DERA1 model and that needs Pref and Qref values to generate the real and reactive power as per the reference. But, these reference values are not given in the CONs of the CMLDBLDGU2. I tried measuring the real and reactive power of DER by porting them to channels from the variables list, and I observed that the values of real and reactive power from DER are zero in the simulation. I used the simulation files provided by JConto's google drive @CMLDxxU2jconto_DF20210923 folder and cmldg.py file. Clarification of this problem will be really helpful for my work.
