I get Undefined function 'abs' for input arguments of type 'Simulink.Parameter' error and I do not know why because I do not use any abs functions. I'm useing simpowersystem modeling and i need to have blocks parameters set as ImportedExtrn storage class.

Are you using the parameter as a mask value? There may be something below the mask that is attempting to use the parameter that cannot handle Simulink.Parameter parameters.

Simpowersystem models are likely masked systems (I don't have it so I can't check). If you use the Simulink.Parameter in the mask of a simpowersystem block there could be a (bad) implementation of abs(parameter) inside that block.
