Multi-zone LVDC distribution systems architecture for facilitating low carbon technologies uptake
Low voltage direct current (LVDC) distribution systems have recently been considered as an alternative approach to provide flexible infrastructure with enhanced controllability to facilitate the integration of low-carbon technologies (LCTs)...
The impact of MVDC upon conventional distance protection schemes in hybrid ac-dc distribution networks
This paper looks at the protection implications of introducing fully controllable, embedded, medium voltage dc (MVDC) power electronic links into power distribution networks. Studies have indicated, protection notwithstanding, that embedded...
Design and integration of an MVDC system on a GB 33kV network
Western Power Distribution was funded through the Low Carbon Networks Fund to deliver an innovation project, Network Equilibrium [1]. A key technical method of this project was the design, testing, implementation and operation of a 33kV AC-...
Analysis of harmonic transfer through an MVDC link
The impact of harmonics and resonances on the medium voltage direct current (MVDC) link embedded in the Anglesey 33 kV distribution networks is evaluated in this paper. The background harmonics at either end of the MVDC link is analysed to ...
Assessment of passive islanding detection methods for DC microgrids
This paper provides an assessment of passive islanding detection methods in DC microgrids. In order to analyse the response of a DC microgrid to an islanding event, DC voltage and current signatures are captured locally at the terminals of ...
Improved droop control with DC grid resonance damping capability
The concept of the so-called droop control has been widely discussed in the literature as the preferred controller for Voltage Source Converter for High Voltage Direct Current (VSC-HVDC) multiterminal and DC grid schemes. Droop control prov...
A realistic telecommunication model for electromagnetic transient simulations and control assessment of multi-terminal VSC-HVDC networks in PSCAD/EMTDC
A telecommunication system is vital for the operation and control of large electric power systems such as present and future multi-terminal HVDC networks. The latency in data transmission, and the variation in latency, known as jitter, are ...
Analysis of steady-state power transfer capability and dynamic performance of VSC-HVDC with impedance-compensated synchronisation method connected to weak AC grid
This paper investigates the steady-state power transfer capability and dynamic performance of the voltage source converter high voltage direct-current (VSC-HVDC) system connected to a weak AC grid that relies on the impedance conditioned ph...
A single pole to ground fault location method for HVDC transmission lines based on coupling characteristics
In this paper, coupling coefficient between conductors is demonstrated as a superior indicator for single pole fault location. A method is proposed to locate faults via estimating the coupling coefficient with the help of single end current...
Novel partial power flow solver for multi — terminal HVDC control
Accurate control of the power flowing through multi-terminal HVDC networks is necessary to ensure that maximum power is being absorbed from the offshore windfarms. The current literature implements a Power Flow Solver to achieve this contro...
