Abstract

The Voltage Source Converter based HVDC provides asynchronous interconnection between two AC systems. The use of VSC HVDC enables independent control of real and reactive power. The VSC based HVDC transmission system consists of two converter stations connected by a dc cable/line. This paper presents modelling and the design of controller for VSC HVDC. The various operating cases of VSC HVDC are considered. In each case there are several controllers gains in HVDC link. A systematic approach is used for selecting the controller parameters and Genetic Algorithm (GA) is used for tuning the controller parameters. The various operating cases of VSC HVDC are considered in controller parameters optimization. The GA enables the usage of the same controller gains for all operating cases while maintaining the system stability.
