For controlling a voltage in a DC power grid comprising a DC voltage controlling master terminal (TM1, TM2) and a DC power controlling slave terminal (TS1,...,TS3), a first tolerance range (U N , ”U) for DC voltages of the master terminal (TM1, TM2) and of the slave terminal (TS1,...,TS3) as well as a second tolerance range ( P S1 , P S1 ,..., P S3 , P S3 ) for a DC power of the slave terminal (TS1,...,TS3) are received. With that, a robust optimization process is run for a set of DC power flow equations. The first and second tolerance range are input to the robust optimization process using the first tolerance range (U N , ”U) as robust optimization constraint and the second tolerance range ( P S1 , P S1 ,..., P S3 , P S3 ) as robust optimization uncertainty. With that, the robust optimization process determines a DC voltage set point (u st1 , u st2 ) for the master terminal (TM1, TM2) so that the set of DC power flow equations and the robust optimization constraint are fulfilled for the second tolerance range ( P S1 , P S1 ,..., P S3 , P S3 ). According to the determined DC voltage set point (u st1 , u st2 ) the DC voltage of the master terminal (TM1, TM2) is controlled. |
