There is an increasing amount of wind farms that need to be connected to the AC transmission network. Offshore wind farms will be connected to the ac system via long submarine cables. Integration of offshore wind farms with HVDC transmission based on Voltage Source Converters (VSC), such as HVDC Light, is an advantage due to regulating properties of HVDC Light. The purpose with the Tjæreborg pr...

Abstract As the use of renewable resources increases transfer power from remote area to consumer is a big challenge. Therefore, Voltage Source Converter High Direct Current (VSC-HVDC) transmission gaining more popularity for integration energy generators consumers using smart grid. Even after many advantages HVDC system it not used popularly due unexpected instability in system. However recent ...

Over the years, high voltage transmission of large energy blocks over long distances has widely developed from Line Commutated Converter (LCC) technology. However, continuous expansion AC network and increase in renewable penetration leads to weakening Electric Power Systems (EPS), causing operational problems for LCC-HVDC. This paper evaluates degree contribution VSC-HVDC on LCC-HVDC dynamic p...

Gerilim kaynaklı dönüştürücülere (VSC) dayalı yüksek gerilim-doğru akım (HVDC) güç sistemleri son yıllarda popüler bir konu haline gelmiştir. Bu makale, zayıf AC sistemi için çeşitli sistem hataları ve aşırı yükleme koşulları altında vektör kontrol tekniği ile VSC tabanlı VSC-HVDC sisteminin modelini performansını incelemektedir. matematiksel modeli, parametrelerini en uygun şekilde ayarlamak e...

Recently, there has been a fast development and deployment of wind energy to meet the increasing electrical power demand and to limit the use of fossil fuels. More and more wind farms are planned far from shore because of good wind condition and less visual impact. This is so called offshore wind farm (OWF). In such a situation, high voltage direct current (HVDC) transmission is a favorable opt...

The purpose of this study is to improve the P-I controllers voltage-source converters (VSC)-based multiterminal high voltage direct-current (MT-HVDC) networks. Since VSCs are non-linear elements MT-HVDC stations, classical optimization methods, which approximately implement linear model optimize VSCs, do not generate optimal results. Therefore, paper presents a novel technique VSC-based grids’ ...

This paper proposes a novel coordinated control strategy for voltage source converter (VSC) based high-voltage direct current (HVDC) grid integrated offshore wind farms (OWFs) to damp the power system oscillations. A feature of this is aiming use DC-link capacitor energy turbines (WTs) reduce interactions between oscillations and HVDC when onshore grid-side VSCs (GSVSCs) modulate active reactiv...

Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs a Dynamic Harmonic Domain (DHD) based framework for dynamic harmonic analysis of VSC-HVDC systems. These systems are wide...
