Voltage Source Converter (VSC) HVDC for Power Transmission – Economic Aspects and Comparison with other AC and DC Technologies KU Leuven
The objective of the WG was to develop an assessment process to evaluate the beneficial impact of VSC-HVDC on power systems. The proposed methodology includes a straightforward analysis of important environmental facts that have to be taken into account for an appropriate assessment. Case studies have been provided in order to demonstrate the application of the proposed methodology. This WG gives a snapshot on the current technology, application ...
Flying-capacitor multilevel converter voltage balance dynamics for pure resistive load Universiteit Gent
Grid voltage control with wind turbine inverters by using grid impedance estimation Universiteit Gent
Currently, distributed generation (DG) units usually do not participate in the primary grid voltage control and inject power regardless. Only when the grid voltage level surpasses a certain threshold, these units shut down to avoid any overvoltage problems. In this paper, a method is developed to control the grid voltage by wind turbines. This way, the grid voltage level improves, and the wind turbine can still generate power under suboptimal ...
Peer-to-Peer-Based Grid Support Functions for Smart Inverters — Distributed Voltage and Frequency Control KU Leuven
Control of distribution networks are facing significant challenges with the increasing penetration of distributed energy resources. The focus of this thesis is to develop active voltage control systems provided by photovoltaic (PV) and PV-battery inverters to mitigate or eliminate voltage problems of distribution networks. Various approaches that combine local and centralized voltage control techniques have been proposed in literature. These ...
Peer-to-peer-based integrated grid voltage support function for smart photovoltaic inverters KU Leuven
The increasing penetration of renewable energy sources is impacting the operation of the distribution grid. Whilst they are currently placing a burden on the distribution grid, it is generally agreed that these sources could also be used for active grid control, thereby contributing to a stable and secure grid. Smart photovoltaic inverters can contribute to active grid control, by expanding their features with added functions. In this paper, we ...
Control strategies for grid-connected inverters enabling power quality improvement and increased penetration of renewable energy resources in the low voltage distribution networks Universiteit Gent
De bezorgdheden omtrent de klimaatsverandering en de onzekere prijzen van fossiele brandstoffen geven aanleiding tot een verhoogde penetratie van hernieuwbare energiebronnen in de elektrische distributienetwerken. Hoewel de verdeelde energiebronnen veel voordelen opleveren in vergelijking met de klassieke gecentraliseerde energieproductie, is het verbinden van deze energiebronnen volgens de fit-and-forget methode geen gepaste oplossing wegens de ...
