“…These five parts are likely to account for 90% of failures disabling the turbines. Frequency converters and generators belong in this category; therefore, development projects involving these components are scrutinized intensely by the customer (see e.g., Baroudi et al, 2007). Each wind farm works to different parameters depending on the local temperature, wind direction, humidity, and other climactic variables.…”

The real problems in diminution of power quality occurs due to the rapid growth of nonlinear load are leads to sudden decrease of source voltage for a few seconds i.e sag, swell, harmonics in source and load current, voltage unbalance etc. All these problems can be compensated by using Unified Power Quality Controller (UPQC) and the operation of UPQC depends upon the available voltage across capacitor present in dc link. If the capacitor voltage is maintained constant then it gives satisfactory performance. The proposed research is basically on designing of Photo Voltaic (PV) /Wind energy fed to the dc link capacitor of UPQC so as to maintain proper voltage across it and operate the UPQC for power quality analysis. The said model is simulated in Matlab and results are verified by using FFT analysis.The proposed PV/ Wind energy-UPQC is design in Matlab simulation for reduction of voltage sag, swell, interruption of voltage, harmonics in load current and compensation of active and reactive power.

The main drawbacks of the renewable sources are the power generation is not continuous and it is season based. To overcome these disadvantages numbers of renewable sources are interconnected [1], [2]. The compensation principle and different control strategies of the UPQC in detail and performance of UPQC is examined by considering, a diode rectifier feeding an RL load (non linear load) that acts as a source of harmonics [3]. The theory, modeling and application of a unified power quality conditioner has been described by [4]. The coordinated and integrated control of solar PV generators with the maximum power point tracking (MPPT) control and battery storage control to provide voltage, frequency (V-f) and P-Q control, respectively, with PV generator and battery storage support to an islanded Microgrid [5]. Femia et al [6] have developed a scheme for maximum power point tracking (MPPT) of solar PV system using perturb and observe method. Gaeid et al [7] have design a unified power quality conditioner (UPQC) including a series and a shunt active power filter (APF) to compensate harmonics in both the distorted supply voltage and nonlinear load current. In the series APF control scheme, a proportional-integral (PI) controller, meanwhile a PI controller and are designed in the shunt APF control scheme to relieve harmonic currents produced by nonlinear loads. Basu et al [8] have made a comparative evaluation of two models of UPQC for suitable interface to enhance power quality. Montero et al [9] have developed number of method...

“…Hence, a trade-off between optimum power coefficient operation and avoidance of rapid shaft torsional torque variations is important in practical implementations for reducing fatigue stresses [36]. But, a transient analysis for wind turbines equipped with a PMSG during a blade pitch control malfunction can be performed with only the MPPT in order to avoid unnecessary modeling of the trade-off as in [37]. The simulation of the blade pitch control malfunction considers that the blade pitch angle control imposes the position of wind gust on the blades in a small time interval, i.e., blades are quickly at the position of the maximum blade pitch angle.…”

This paper is on a wind energy conversion system simulation of a transient analysis due to a blade pitch control malfunction. The aim of the transient analysis is the study of the behavior of a back-to-back multiple point clamped five-level full-power converter implemented in a wind energy conversion system equipped with a permanent magnet synchronous generator. An alternate current link connects the system to the grid. The drive train is modeled by a three-mass model in order to simulate the dynamic effect of the wind on the tower. The control strategy is based on fractional-order control. Unbalance voltages in the DC-link capacitors are lessen due to the control strategy, balancing the capacitor banks voltages by a selection of the output voltage vectors. Simulation studies are carried out to evaluate not only the system behavior, but also the quality of the energy injected into the electric grid. © 2015 Elsevier Ltd.

IntroductionEnvironmental problems such as global warming and habitat preservation have to be faced by the society in nowadays in order to achieve a sustainable development. One of the causes for the global warming is said to be the increase on the level of CO 2 in the atmosphere due to fossil fuel burning [1]. However, nowadays fossil fuel burning is needed for supplying the majority of the energy demand [2]. Research and development is on the way to achieve lower pollutants emissions on conversion of energy to convenient forms of usage in order to achieve a sustainable development. Conversion of energy from renewable energy sources are in nowadays a political attractive option [3] and a wind energy conversion system (WECS) is an economically viable exploitation [4], experiencing a significant expansion [5,6]. Although, onshore WECS deployments are cheaper than offshore ones, new suitable available onshore sites for deployments are becoming scarce, particularly in Europe [7]. So, the offshore WECS is becoming a further attractive option.
