“…The emission from individual wind turbines has been studied [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Generally, it can be concluded that the emission from individual turbines is relatively small.…”

This paper discusses a number of ways in which wind power installations can impact the harmonic levels in the power system. Wind turbines are an additional source of harmonic emission, especially when it concerns ''non-characteristic harmonics.'' Parallel resonances can amplify the emission from individual turbines. A mathematical model is developed to quantify this amplification. Series resonances can result in high currents, driven by the background voltage distortion in the transmission grid, flowing into the wind park. Weakening of the transmission grid will increase lower order harmonics but reduce higher order harmonics.

a b s t r a c tThis paper presents harmonic measurements from three individual wind turbines (2 and 2.5 MW size). Both harmonics and interharmonics have been evaluated, especially with reference to variations in the active-power production. The overall spectra reveal that emission components may occur at any frequency and not only at odd harmonics. Interharmonics and even harmonics emitted from wind turbines are relatively high. Individual frequency components depend on the power production in different ways: characteristic harmonics are independent of power; interharmonics show a strong correlation with power; other harmonic and interharmonic components present various patterns. It is concluded that the power production is not the only factor determining the current emission of a wind energy conversion system.

“…It contributes to the level of the flicker and has an interference with control and protection signals in power lines [92], which are regarded as the most harmful effects on the power system. Wind turbine power quality standard IEC 61400-21 2 nd edition released in 2008, along with harmonic measurement standard IEC 61000-4-7, provides the requirements for on current harmonics, current interharmonics and higher current components to be measured and reported in modern WECSs [80,93,94].…”

“…Another focus of the new grid code is the requirement for wind turbines to support the power quality control on the grid such as voltage/frequency stability control, active/reactive power regulation, harmonics/interharmonics emission and flicker emission and so forth [77][78][79]. International Electrotechnical Commission (IEC) has also released standards on power quality for gridconnected wind turbines, which are IEC 61400-21 in 2001 and its second edition in 2008 [80].…”

This paper focuses on the wind energy conversion system (WECS) with the three main electrical aspects: 1) wind turbine generators (WTGs), 2) power electronics converters (PECs) and 3) grid-connection issues. The current state of wind turbine generators are discussed and compared in some criteria along with the trends in the current WECS market, which are 'Variable Speed', 'Multi-MW' and 'Offshore'. In addition, the other crucial component in the WECS, PECs will be discussed with its topologies available in the current WECS market along with their modulation strategies. Moreover, three main issues of the WECS associating with the grid-connection, fault-ride through (FRT) capability, harmonics/interharmonics emission and flicker, which are the power quality issues, will be discussed due to the increasing responsibility of WECS as utility power station. Some key findings from the review such as the attractiveness of BDFRG are presented in the conclusion of this paper.
