How to set different load models in dynamic simulation?

I want to run dynamic simulation with different load models, but don't know how to do that. I've read Program Application Guide Volume2, in Chapter21.2 it introduces many load characteristic models such as LDFR,CLOD and composite load models, etc.

Does anyone know how to realize it? Can this process be saved in .dyr file or need other python command to realize it? (If no python, using GUI to directly operate is also OK)

Thanks~ always waiting for answer!

Dynamic load models are added just like generators in .dyr file. Load models can be added by either bus, zone, area, or owner. I would take a look at section 9 of the PSSE Model Library document.

The following is an example of a "standard" IEEE Load Model used in the WECC:

 [AREA NUMBER] 'IEELAR' *     0.0000       1.0000       0.0000       1.0000
      0.0000       0.0000       1.0000      -1.0000       2.0000
      1.0000       0.0000       2.0000       1.0000       0.0000    /

Change [AREA NUMBER] to the area of your choice.

I've tried that before.. But every time I did that the PSSE would quit accidently, I'm wondering if the parameter was wrong..

Please see edited answer for example of IEEE load model.

Really so much thanks for your help! As you saida, there are 7 models including CIM5/CIM6/CIMW/CLOD/EXTL/IEEL/LDFR in .dyr file. I think the parameters you gave are for IEEL, but what about other six models? It keeps giving me warning and error for my wrong parameters :(
