“…Controlling a wind turbine involves both fast and slow control dynamics [22]- [34]. Overall the power has to be controlled by means of the aerodynamic system and has to react based on a set-point given by a dispatched center or locally with the goal to maximize the power production based on the available wind power.…”

-The electrical energy consumption continues to grow and more applications will be based on electricity in the next decades. We can expect that more 60 % of all energy consumption will be converted and used as electricity. It is a demand that production, distribution and use of electrical energy are done as efficiently as possible. Further, emerging climate changes argues to find future solutions which also are sustainable. Two major technologies will play important roles to solve parts of those future problems. One is the change the electrical power production from conventional, fossil (and short term) based energy sources to renewable energy sources. Another is to use power electronics to achieve high efficiency in power generation, transmission/distribution and utilization. This paper discuss trends of the most promising renewable energy sources, wind energy, which ,integrated with power electronics, is changing the future electrical infrastructure and also contributes steadily to non-carbon based electricity production. The paper's focus is on the power electronics technologies used in wind turbine systems.

“…Nowadays, when a grid fault occurs, grid connected power converters are required not only to remain connected to the grid but also they must reduce their active power delivery and increase the reactive power injection for supporting the grid. Numerous research works have reported different power control strategies for DGPS or shunt connected power electronics converters, like STATCOMs, for operating them under abnormal grid conditions [2]- [4]. Since most of the grid faults are unbalanced faults, several research works have done for injecting unbalanced reactive currents to boost the positive sequence voltage as well as minimizing the negative sequence component.…”

Abstract-The safe operation of grid connected power converters during abnormal condition is a key issue in order to guarantee its operation and to avoid undesired trips. In this paper different control methods for the operation of a D-STATCOM are evaluated, where the reference currents are determined in such a way that none of the phase currents goes over the limits, as well as the DC voltage fluctuations remain in safe operation limit. Therefore, the contribution of this paper lays on the combination of the DC voltage oscillations and the current limit control. As it is shown in the following, three different control strategies are evaluated. The amplitude of the oscillations which are superimposed on the DC voltage as well as peak amplitude of the phase currents are calculated for each, considering a generic imbalance in the network. The effectiveness of the presented control strategies are verified by simulating a D-STATCOM tied to an industrial distribution network. Moreover a scaled scenario has been reproduced experimentally which shows that the results cope well with the analytical equations and the simulation results.

“…But all these suffer from the demerits of poor device utilization; the produced variable DC-link voltage causes distortion of currents and voltage of generator and has poor power factor operation. Out of these configurations, two commonly investigated matured alternatives for wind power generation purposes are the AC/DC/AC converter [6][7][8][9][10] and the matrix converter (MC) [11][12][13][14][15][16][17][18]. Although the AC/DC/AC converter has a high energy density and is relatively low in price, there is a serious concern with its large DC-link capacitor due to its size, weight, volume, and premature failure [15,17].…”

This article presents the development of a novel control for matrix converter interfaced permanent magnet wind energy conversion system. Here, an adaptive fuzzy control algorithm incorporated with a reversed matrix converter is proposed to yield maximum energy with enhanced dynamic performance and low harmonic characteristics. The control algorithm is implemented using a dSPACE DS1104 real-time board (dSPACE, Paderborn, Germany). Feasibility of the proposed system has been verified through simulation and experiment results using a laboratory 1.2-kW prototype of a wind energy conversion system under dynamic conditions.
