Integration of the VSC-based HVDC model into an OPF Matlab-based analysis

This paper presents the integration of the Voltage Source Converted-High Voltage Direct Current model| (VSCHVDC) into a conventional Optimal Power Flow (OPF) formulation. The assembled VSC-HVDC-OPF model is computationally implemented and solved by using the Matlab ® optimization toolbox. In this sense, the development complexity degree of the proposed implementation is equivalent to that required by commercial optimization packages for solving optimization models. Therefore, this proposal hugely reduces the time to the implementation and for obtaining results of an OPF analysis of power systems with VSC-HVDC devices. In order to illustrate numerically the prowess of the proposed Matlab based implementation to solve the VSC-HVDC-OPF model, two numerical examples with the IEEE two-area benchmark power system and the 46-machine, 190-bus model of Mexican system are presented.
