You need to create a callback routine for CPF that plots what you need and set it in the options struct.
mpopt = mpoption(‘cpf.user_callback’,’cpf_user_callback’); where cpf_user_callback is the name of your callback routine. Read pages 38 - 40 of the manual.

But how can i plot real power flow at each iteration of cpf.

The lambdas after each predictor and corrector step, respectively, are returned in results.cpf.lam_p and results.cpf.lam_c. If you mean the full power flow solution, then you’ll have to use the appropriate lambda to set set up the injections for the case, according to equations (5.2)–(5.4), and initialize the power flow with the corresponding bus voltages (from results.cpf.V_p or results.cpf.V_c) and run a simple power flow.

These are just systems whose data has been published and then used by many researchers.

I know these systems represent some portions of existing power grid networks for example IEEE-14 Bus system is a portion of American Electric Power System (in the Midwestern US) as of February, 1962. But other than this is there any other reason of standardization of the test systems?
