Abstract

The paper considers the optimal power flow (OPF) of a meshed AC/DC power transmission network with voltage source converter based multi-terminal DC (VSC-MTDC) networks. The OPF problem is formulated to minimize the transmission loss of the whole AC/DC network with two different VSC control strategies considered, constant DC voltage control (master-slave control) and DC voltage droop control. In addition, Grid Code compliance of wind farms is also embedded in the OPF formulation. The presented OPF is evaluated and demonstrated in the paper by two example meshed AC/DC power systems.
