“…In this configuration, rectifiers on offshore platform and HVDC system form a MTHVDC system. Livani et al 14 and Jovcic and Strachan 20 indicated that MTHVDC and generator groups are stable operation despite the different wind speeds among a cluster. It is noted that this paper focuses only on the control strategies of the converters in the wind farm, so all wind turbines are assumed to have the same wind speed.…”

“…The FRT ability of offshore wind farm using voltage source converter (VSC)-HVDC connection has also been investigated and evaluated in various publications. [14][15][16][17] The offshore wind farms are connected to an onshore grid consisting of two weak grids compared to the rated power of these offshore wind farms. 14,15 Because these two weak grids are in parallel, they can form a quite strong equivalent grid.…”

Large offshore wind farms using high voltage direct current transmission system have been considered and exploited in a few countries in the world. Maintaining stable operation of the wind farm is an important issue. Previous studies only proposed some methods to improve the fault ride-through capability of the wind farm as it is connected to a quite strong system, resulting in recovery of the voltage at the point of common coupling (PCC) after clearance of onshore gridfault. This paper will evaluate the PCC voltage recovery ability of the wind farm when it is connected to a weak grid and suggest a new method to overcome unrecoverable voltage problem. The effectiveness of the proposed control strategies is proven by simulation results. V C 2012 American Institute of Physics.

“…Traditionally the interconnection of wind farms is based upon AC transmission or HVDC transmission [1][2] [3]. AC technology for transmitting wind power is commonly used, but has encountered some problems including the instability of voltage and frequency variation brought about by the fluctuation of wind source [3].…”

With the emerging of various transmission technologies, alternate wind farm configurations have been proposed to integrate different combinations of AC, HVDC and Low-frequency AC for in-farm and out-of-farm transmission. The problems of cost evaluation and kV level selection are raised for the alternate wind farm configurations. This paper presents the cost analysis method and the optimal kV level selection approach for the alternate configurations discussed. The analyzed cost consists of operational cost, acquisition cost and maintenance cost. The optimal kV level is selected based on the minimization of the total annualized cost of the wind farm. One of the proposed alternate configurations is used as a case study to demonstrate the cost analysis and optimal kV level selection methods. The kV level selection results and the minimum cost of all the eight alternate configurations proposed are also provided.
