Electronically controlled capacitive energy storage element for DC grids

TL;DR: In this paper, the authors propose a handshaking method to locate and isolate the faulted dc line and restore the MTDC without telecommunication, which is shown to be more economical than the dc circuit breakers.

TL;DR: In this article, the authors present a review on the improvement of reliability of dc link in power electronic converters from two aspects: reliability-oriented dc-link design solutions; and conditioning monitoring of DC-link capacitors during operation.

TL;DR: In this article, an earthed bipole HVDC grid was modeled in PSCAD, and using simulation results, the necessity of di/dt limiting inductors to contain the rise of fault currents within the capacity of current hybrid dc breakers was demonstrated.

TL;DR: The first dedicated reference to the latest HVDC technologies and DC grid developments; this is an essential resource for graduate students and researchers as well as engineers and professionals working on the design, modeling and operation of DC grids andHVDC.
