One of the ancillary services that can be provided by Multi-terminal Direct Current (MTDC) grid to connected ac grids is power oscillation damping (POD). However, using PODs at multiple terminals of an MTDC grid results in multi-loop, multi-variable control system. Such control systems inherently ha...

This paper presents a novel frequency-domain approach towards the control design for parallel grid-connected voltage source inverters (VSIs) with LCL output filters. The proposed method allows to design the controllers of multiple VSIs in a single step, and inherently attenuates the resonances intro...

The prospect of future multivendor HVDC systems has led to concerns about interoperability between converter terminals based on different technologies. This paper investigates the interoperability of converter terminals in a small-scale experimental setup, consisting of two 2-level (2L) Voltage Sour...

The real-world interaction of an offshore wind farm with an HVDC is complex due issues such as noise, randomness of event timings, and hardware design issues that are not well explored. Numerical simulations are widely accepted and cost effective tool to test a wide variety of different cases, howev...

The concept and experimental validation process of the Web-of-Cells (WoC) based Post-Primary Voltage Control (PPVC) developed in EU FP7 project ELECTRA IRP is presented in this paper. The main objective of PPVC is to provide an optimal and local voltage control replacing the conventional secondary a...

This paper presents a comprehensive modelling approach to obtain a small-signal model of a Modular Multilevel Converter (MMC)-based High Voltage Direct Current (HVDC) link interfacing two large asynchronous ac systems. Detailed models are used to represent synchronous generators, MMC converters and ...

The paper presents an integrated modelling platform that can be used to assess the dynamic performance of an offshore wind turbine mounted on a spar-buoy type floater. Sub-models of generator and converter controllers and the power network are combined with a state-of-the-art numerical simulation of...

...s paper presents an experimental verification of a voltage droop control for a multi-terminal HVDC system for the grid integration of offshore wind farms. The laboratory setup is composed by four voltage-source converter terminals which aim to emulate behavior of the future power grid in the North S...
