Stability analysis of multi-infeed HVDC system applying VSC-HVDC
IEEE PES General Meeting, 2010This paper presents a general model of dual infeed HVDC system applying VSC-HVDC, which can be used as an element in large multi infeed HVDC system. The model may have different structure under different grid faults because of the action of breakers. Hence power flow of the system based on this model is analyzed under steady state and different kinds ...

Nonlinear dynamics in HVDC systems
IEEE Transactions on Power Delivery, 1999Voltage instability in AC power systems has been widely studied from a nonlinear dynamical system perspective. In contrast, this approach for HVDC systems is of recent origin and rudimentary, therefore much basic work in this area remains to be developed.

Multiterminal HVDC Power Systems
IEEE Transactions on Power Apparatus and Systems, 1980Papers published over a 17 year period, on the concept of extending 2-terminal HVdc transmission to multiterminal systems, are reviewed. In classifying the contributions, the design and performance expectations are discussed and the prospects for applications are evaluated. Reference is also made to the implications of dc interrupting switches.

Modeling and Control of HVDC Systems
2019This chapter gives a brief overview of modeling and control of high voltage DC (HVDC) systems. First, different configurations of HVDC transmission systems are mentioned, which is followed by the state-space averaged modeling of line-commutated converter (LCC) HVDC systems and their control modes.

Nonlinear Control of HVDC Systems
2001A DC Electric Power Transmission System, with its inherent advantages, such as fast regulation, flexible operation, high-power transmission, and the ability to rapidly regulate active power flow, has been widely applied to high-power transmission over long distance, regional power systems inter- connection, and undersea electric power transmission.

HVDC and power electronic systems
2001HVDC is in many respects the ultimate power electronics based FACTS device which can act within an existing AC network or even replace parts of it. In evaluating the usefulness of HVDC it is important to remember the controllability which it adds to the power system in addition to its bulk power transfer capabilities.
