Dear Jascha Korscheck,
I think you should change the slack bus voltage magnitude like this:

define_constants;
mpc = loadcase('test');     % "test" is the name of your casefile
mpc.bus(1, VM) = 1.06 ;  % 1 is your Slack bus number %1.06 p.u. is just an example voltage magnitude for slack bus

Best wishes,
Ehsan

    Dear MATPOWER-Team

    I've described a grid with the name "test". This grid has only
    three lines with four buses.

    Bus 1 is connect over line 1 to bus 2, bus is connect over line 2
    with bus 3 and bus 3 is connect over line 3 with bus 4.

    Bus 1 is my slag.  Is the slag-voltage always 1 p.u. or can I
    change this value?

    If I can change it, with  which command can I change it?

    I hope you can help me.
