Optimal power flow control remains one of the main challenges to be solved before large multi-terminal dc (MTdc) networks can be successfully developed. This article employs a novel strategy to achieve optimal power flow (OPF) control in MTdc networks for large offshore wind power plants (OWPP). The strategy, called Distributed Voltage Control (DVC), is validated on an experimental low-voltage laboratory...
Lesnicar and Marquardt introduced a Modular Multilevel Converter (MMC) topology back in 2003. Although this topology has received a great deal of attention in recent years by both the research community and industry, hitherto no steady-state model has been developed which accurately captured all the relevant power losses while being computationally light. Hence, the aim of this paper is to introduce...
This paper compares how a dc fault affects a multiterminal dc (MTdc) network depending on the HVDC transmission system topology. To this end, a six-step methodology is proposed for the selection of the necessary dc fault protection measures. The network consists of four voltage-source converters converters radially connected. The converters natural fault response to a dc fault for the different topologies...
The paper describes blended learning approach to teaching uncontrolled rectifiers. It is based on ldquolearning by doingrdquo paradigm supported by several learning tools: electronic course materials, interactive simulation, laboratory plants and real experiments accessed by Web Publishing Tools under LabVIEW. Studying and experimenting access is opened for 24 hours a day, 7 days a week under the...
In this paper it is shown that the switching of the power electronic switches can be cause (source) of the flicker. A new switching technique implemented to control a single-phase tap changed-transformer in order to eliminate the internal flicker problem is investigated. The suggested method was subjected to both theoretical and experimental investigations. Further in this paper a method to mitigate...
