A Diode-MMC AC/DC Hub for Connecting Offshore Wind Farm and Offshore Production Platform
نویسندگان
چکیده
A diode rectifier-modular multilevel converter AC/DC hub (DR-MMC Hub) is proposed to integrate offshore wind power the onshore DC network and production platforms (e.g., oil/gas hydrogen plants) with different voltage levels. The DR MMCs are connected in parallel at AC collection power, series terminals of platform network. Compared conventional parallel-connected DR-MMC HVDC systems, reduces required MMC rating, leading lower investment cost loss. System control designed based on operation requirements platform, considering modes (power or control). behaviors during faults investigated, hybrid half-bridge full-bridge sub-modules (HBSMs FBSMs) used for safe faults. Simulation results PSCAD/EMTDC validate hub.

Performance Analysis of Hybrid HVDC Transmission Systems for Connecting Offshore Wind Farm to Onshore Grid
This paper presents the performance analysis of DFIG based off shore wind farm feeding to large power system through a hybrid HVDC link. The hybrid HVDC link consists of a line commutated converter based inverter and voltage source converter based rectifier. The active and reactive power of off shore station is controlled using voltage source converter based rectifier controller and the dc line...
متن کاملA New Control Method for Smoothing PMSG-based Offshore Wind Farm Output Power
Nowadays, propagation of wind turbines make challenges to supply safe power to the grid. Because of wind speed changes, supervisors are concerned to wind turbines, be able to produce appropriate electric power during the wind speed changes. As a matter of fact, investors are mostly like to invest on offshore wind farms, because of their more stable and continuous wind speed rather than onshore ...
متن کاملAutomated grid connection design process for offshore wind farm clusters
An automated grid connection design process for offshore wind farm clusters that takes into account the variability of wind and power demand/prices is demonstrated on a 7200 MW case study inspired by Dogger Bank, using the Net-Op planning tool. Two modelling approaches for demand, generation and prices are outlined and compared for this case study. Both approaches result in the same optimal off...
متن کاملImprovement of the Wind Farm Model Flap for Offshore Applications
The wind farm program FLaP (Farm Layout Program), developed at the University of Oldenburg, has been extended to improve the description of wake development in offshore conditions. Especially the low ambient turbulence and the effect of atmospheric stability have been addressed. Model results have been compared with measured vertical wake profiles and mean turbulence intensities from the Danish...
متن کاملAirborne sound propagation over sea during offshore wind farm piling.
Offshore piling for wind farm construction has attracted a lot of attention in recent years due to the extremely high noise emission levels associated with such operations. While underwater noise levels were shown to be harmful for the marine biology, the propagation of airborne piling noise over sea has not been studied in detail before. In this study, detailed numerical calculations have been...
