Multilevel converters have become the real option for high voltage and current applications for power systems, especially for FACTS controllers. The Static Compensator (STATCOM) is a shunt-type device which can be used to control reactive power in a network as of its many advantages such as fast speed, compact footprint and small harmonics. In this work a comparison between two of the most promising...
The present article evaluates the performance of different MMC-HVDC converter control strategies for both internal and external control, and analyzes the performance and compatibility with the current vector control method. A full analytical expression of the system dynamics including the grid connection is presented and two novel inner control methods are exposed.
The objective of this article is to compare two concurrent VSC-based topologies suitable to interconnect two MV distribution grids. These power-electronics-based devices must not only control the power flow between both grids, but also compensate for power quality phenomena. For this reason, size comparison is made separately according to the function that they develop. The first part of the paper...
In spite of the existing current deployment barriers, power-electronics-based devices are presented as potential candidates to interconnect active distribution grids. The objective of the present article is to expose a comparison between two concurrent VSC-based topologies suitable to control power flow between two MV distribution networks, namely the MVDC and D-UPFC. Mathematical formulae necessary...
This paper presents a project that is being carried out by Endesa in Spain with the aim of controlling peak demand by modifying the consumption of customers within the small and medium enterprise sector. A full load control architecture is being developed and different pilot tests are being specified.
