Abstract
This paper presents a general model of dual infeedHVDC system applying VSC-HVDC, which can be used as anelement in large multi infeed HVDC system. The model may havedifferent structure under different grid faults because of theaction of breakers. Hence power flow of the system based on thismodel is analyzed under steady state and different kinds of gridfault transient situations. Two main control methods applied onVSC-HVDC page link in this dual infeed HVDC system areinvestigated, and comparative analysis of them under transie ....etc

A large interest in renewable energy systems has been developed to mitigate the green house effect. In Western Europe, the focus is thus, on wind power and especially on offshore locations, due to higher energy production, a longer expected life time and lack of suitable wind turbine sites on land. A DC cable is the preferred choice when connecting large offshore wind farms to the grid. The utilization of the Dc cables was enabled by the new HVDC transmission technology using voltage sourced converters. The offshore windfarms that are being bui ....etc

H-BRIDGE VSC WITH A T-CONNECTED TRANSFORMER BASED
THREE-PHASE FOUR-WIRE DSTATCOM FOR POWER QUALITY
IMPROVEMENT


I. INTRODUCTION


THE present day ac power distribution systems is
suffering from severe power quality problems. These
power quality problems include high reactive power
burden, harmonics currents, load unbalance, excessive
neutral current etc. . The power quality at the point
of common coupling (PCC) with the utility grid is

MODELING AND APPLICATION OF VSC-HVDC IN THE
EUROPEAN TRANSMISSION SYSTEM


Abstract –

The present paper focuses on the technical,
environmental, and economic features of VSC-based
HVDC technologies. The aim is to investigate the impact of
VSC-HVDC on the European power system: specific attention
is paid to the transmission capacity enhancement
attainable in targeted applications. Towards this purpose,
an original steady state model of the VSC-HVDC is presented
and tested. Then, a techno-economic analysi ....etc

VOLTAGE SOURCE CONVERTER TOPOLOGY FOR HVDC GRID CONNECTION OF OFFSHORE WIND FARMS
ABSTRACT
Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connection to the AC network. HVDC systems based on voltage source converters (VSC) are a promising alternative to conventional AC transmission above a certain cable length. This paper p ....etc

POWER QUALITY MEASUREMENTS PERFORMED ON
WIND FARMS IN TURKISH POWER SYSTEM
ABSTRACT
The wind farm integration may cause power quality concerns in power systems.
Integration of large scale wind farms into power systems presents some challenges
that must be addressed such as system operation and control, system stability, and
the power quality. Therefore, determining how much the power quality would be
affected by fluctuant power production and by the connection of the wind turbines
to the power system is the most important issue ....etc

STATCOM-controlled HVDC Power Transmission for Large
Offshore Wind Farms: Engineering Issues
Abstract –
The paper considers a solution for integration of
large offshore DFIG-based wind farms with a common collection
bus controlled by a STATCOM into the main onshore grid
using line-commutated HVDC connection. A design procedure
is described and the controlled system is validated using
PSCAD/EMTDC simulations confirming high performance of
the proposed control strategy in both normal operation conditions
and faults. Engineeri ....etc
