This looks to me like it could be an issue with conflicting MATPOWER versions in the Matlab path. Or, is it possible that you are loading a MAT-file created with one version of MATPOWER and attempting to use it in a different version of MATPOWER?
I’d start by making sure you have the latest MATPOWER version on all machines and that your Matlab path does not contain any older MATPOWER functions.
