Multi-objectives OPF of AC-DC systems considering VSC-HVDC integration

The existing optimal power flow (OPF) of AC-DC systems considering VSC-HVDC integration is a single-objective optimization problem. This paper proposes a multi-objectives OPF model of AC-DC Systems considering VSC-HVDC integration, which taking into account the minimum net loss, the voltage and transient stability constraints. To effectively solve the proposed model, this paper presents a mixed solving method, i.e. primal-dual interior point method for solving continuous variables and NSGA2 for solving discrete variables. Tests on IEEE benchmark systems illustrate the effectiveness and efficiency of the proposed approach.
