“…The simulation was done in Matlab using the SimPowerSystem Toolbox [9]. A wind turbine generates power and accordingly a mechanical torque on the rotating shaft, while the electrical machine produce an opposing electromagnetic torque [4]. In steady state operation, the mechanical torque is converted to real electrical power and delivered to the grid.…”

“…So far, the electrical distribution networks were designed and operated under the assumption of centralized generation and an energy flow from the substation to the consumer. It is no more the case [3,4]. The connection of wind generators could lead to many disturbances, such as: voltage fluctuations, flickers, harmonics, instability, blind power regulation problems, and transients [10].…”

Abstract-precise computation of current components is a key prerequisite for reliable assessment of power quality. Especially in networks with wind generation we may observe increased number of possible disturbing phenomena. This paper presents an approach to accurate computation of currents components with two similar parametric methods based on singular value decomposition (SVD) and Prony model. Those methods seem to be applicable for the detection of non integer multiples of the main frequency in decaying signals. Results of both methods have been compared and evaluated. with respect to traditional Fourier method.

“…Offshore wind farms with a capacity of hundreds of MWs are large enough to replace conventional power plants. As a result, the impacts of large OWF on the power system stability will be more significant [3]. Moreover, the dynamic behaviour of VSC-HVDC transmission system during grid disturbances is different from the well-known ac transmission systems [4].…”

With the increased levels of offshore wind power penetration into power systems, the impact of offshore wind power on stability of power systems require more investigation. In this paper, the effects of a large scale doubly fed induction generator (DFIG) based offshore wind farm (OWF) on power system stability are examined. The OWF is connected to the main onshore grid through a voltage source converter (VSC) based high voltage direct current (HVDC) link. A large scale DFIG based OWF is connected to the New England 10-machine 39-bus test system through a VSC-HVDC. One of the synchronous generators in the test system is replaced by an OWF with an equivalent generated power. As the voltage source converter can control the active and reactive power independently, the use of the onshore side converter to control its terminal voltage is investigated. The behaviour of the test system is evaluated under both small and large grid disturbances in both cases with and without the offshore wind farm.

Summary Based on the analysis of the short current of the fixed speed induction generator (FSIG) under symmetrical system faults, a strategy using the dynamic voltage restorer (DVR) is proposed to improve the low‐voltage ride through (LVRT) capability of FSIGs. During the system fault, LVRT‐DVR is connected in series between the grid and the generator by switching‐off the by‐pass bidirectional thyristors and provides a compensating voltage to isolate FSIG from the system fault. To increase the switch‐in speed of LVRT‐DVR, an antivoltage technique is used to shut the thyristors off immediately. After the fault is cleared, the phase‐shifting control is applied to avoid phase jumps of the FSIG terminal voltage. The PSCAD/EMTDC simulation and field tests have been carried out to prove the effectiveness of the proposed LVRT strategy, and related conclusions and comments are summarized.
