Renewable energy sources have high penetration in today's power grid. Efficient transfer of DC power using existing AC transmission infrastructure is an economically viable means to use renewable energy sources. On the other hand, in AC power transmi

Compared with the traditional AC power transmission system, the short-circuit current of HVDC grid dc side do not has natural zero-crossing, rises rapidly and is larger. Fault current limitation problem has become one of the major effects which const

In this paper, three configurations of three-phase ac-dc cascaded converters are presented. They are referred as basic configurations, and are composed by two three-phase bridges, where the second bridge is cascaded to the first by means of a three-p

Due to the recent sub-synchronous oscillations (SSO) events, most independent system operators (ISO) require a study that demonstrates immunity of wind projects with respect to SSO prior to energization. For this study, we consider a wind project sit

In this paper, a new topology of three-phase series voltage source converter is proposed, which is cascaded with the three-phase system by means of only two single-phase or one two-phase transformer. The proposed cascaded converter is presented as a

This paper proposes a modular multilevel converter (MMC) topology, designed particularly for load balancing in 50 Hz railway applications. The asymmetrical character of the traction load requires higher device rating for a Double-star or Delta-connec
