In this paper, a model is presented for the optimal power flow of an HVAC/HVDC transmission network. OPF is a fundamental tool in power system operation and planning. The model proposed for optimal power flow includes network control parameters settings and HVDC links parameters tunings. Also, excessive equipment installation for appropriate operation of the network is minimized, while the network security margin is maximized. To solve the proposed model, a hybrid evolutionary algorithm by combining Particle Swarm Optimization (PSO) and Differential Evolution (DE) is proposed. The methodology is tested on IEEE-30 test system and compared with the results from other OPF techniques. Also the impact of HVDC links on OPF studies is illustrated by numerical examples.
