Application of hybrid real-time simulation concept for modeling of HVDC back-to-back link

Abstract

The application of new technologies considerably complicates the structure and the configuration of the electric grids, changes its dynamic properties and creates new challenges to power system planning and operation for providing reliable and efficient use of intelligent electrical power systems. Considering of well-known specificity of electrical power systems operation, the modelling is the main way of effective solution of the problems. Hybrid simulation method is chosen as the one of the most appropriate approach. Adequate modeling of HVDC devices defines the inadmissible of separate simulation of different modes in equipment and electrical grids as a whole. It is proves by carried out research of hybrid simulation technique witch combine the different simulation approaches.
