Abstract: This paper presents an optimal power flow for multi-terminal High voltage Direct current system (MT-HVDC) based on Genetic algorithm by using MATLAB R2018a, the results show the big effect of DC/DC losses on OPF and made a comparison between OPF with DC/DC converter losses and without considering this losses. The paper shows the effect of DC/DC converter losses on total fuel cost and transmission line losses, The voltage deviation is shown in result. In this paper IEEE 30 Bus system take as a case study with modified DC generation system connect on Bus number 11 and 13 with two AC/DC and one DC/DC converters in addition to two separate DC generators which can be PV power plants
