VSC-HVDC model-based power system optimal power flow algorithm and analysis

This paper presents a power system operation optimization algorithm including VSC-HVDC (Voltage Source Converter - High-Voltage Direct Current) lines using PD-IP (primal-dual interior point) Newton-type OPF (optimal power flow). The VSC-HVDC links have the ability to exert instantaneous power control in neighboring AC systems. Moreover, the VSC-HVDC technology is fit for meeting the growing needs of the DER (distributed energy resource) connection, such as with wind power generation in power systems. The output results for the voltage and the angle are shown by the simulation for the insertion of VSC-HVDC line in the IEEE 30-bus power system. Simulations are executed by the MATPOWER (MATLAB power system simulation) tool for the optimal power flow.
