High Voltage Direct Current Transmission
2012This chapter introduces the two main types of high-voltage direct-current (HVDC) transmission, i.e., the line-commutated current source converter (CSC) technology and its self-commutating voltage source converter (VSC) counterpart, and describes how both technologies can play a crucial role in the further development of power transmission systems.

High-Voltage Direct Current Transmission
2020The HVDC transmission is advantageous for power delivery over long distances and asynchronous interconnections by using overhead lines or underground cables. One of the most important aspects of HVDC systems is its fast and stable controllability [6]. Until recently, the classic HVDC transmission based on thyristors was used for power conversion from ...

The History of High Voltage Direct Current Transmission
Australian Journal of Multi-Disciplinary Engineering, 2010Transmission of electricity by high voltage direct current (HVDC) has provided the electric power industry with a powerful tool to move large quantities of electricity over great distances and also to expand the capacity to transmit electricity by undersea cables.

Adaptive Modulation for DFIG and STATCOM With High-Voltage Direct Current Transmission
IEEE Transactions on Neural Networks and Learning Systems, 2016This paper develops an adaptive modulation approach for power system control based on the approximate/adaptive dynamic programming method, namely, the goal representation heuristic dynamic programming (GrHDP). In particular, we focus on the fault recovery problem of a doubly fed induction generator (DFIG)-based wind farm and a static synchronous ...
