“…The converter usually proposed is the 3-level diode-clamped converter, producing a 3.3kV output with 4500V switching devices [6], [7], [9]. A larger number of levels would reduce the output voltage distortion, reducing the size of the output filter and allowing the use of cheaper switching devices with a lower voltage rating for the same output voltage [5].…”

Abstract-Modular generator and converter topologies are being pursued for large offshore wind turbines to achieve fault tolerance and high reliability. A centralized controller presents a single critical point of failure which has prevented a truly modular and fault tolerant system from being obtained. This study analyses the inverter circuit control requirements during normal operation and grid fault ride-through, and proposes a distributed controller design to allow inverter modules to operate independently of each other. All the modules independently estimate the grid voltage magnitude and position, and the modules are synchronised together over a CAN bus. The CAN bus is also used to interleave the PWM switching of the modules and synchronise the ADC sampling. The controller structure and algorithms are tested by laboratory experiments with respect to normal operation, initial synchronization to the grid, module fault tolerance and grid fault ride-through.

“…The PI-based DC-link voltage controller is simple to implement and is therefore preferred by most researchers, including [30], [32], [35], [38], [39], [55], [59], [60]- [62], [67], [75], [76], [79], [81], [92], [101]- [103], [107], [116]- [118], [120], [122]- [128], [130], [134], [136], [139], [140], [145], [146], [148], [155], [157], [160], [161], [165], [167], [171], and [184]- [186].…”

Recent developments in power electronics technology have spurred interest in the use of renewable energy sources as distributed generation (DG) generators. The key component in DG generators is a grid-connected inverter that serves as an effective interface between the renewable energy source and the utility grid. The multifunctional inverter (MFI) is special type of grid-connected inverter that has elicited much attention in recent years. MFIs not only generate power for DGs but also provide increased functionality through improved power quality and voltage and reactive power support; thus, the capability of the auxiliary service for the utility grid is improved. This paper presents a comprehensive review of the various MFI system configurations for single-phase (two-wire) and three-phase (three-or four-wire) systems and control strategies for the compensation of different power quality problems. The advances in practical applications and recent research on MFIs are presented through a review of nearly 200 papers.

“…A common way of compensating for the wide range of voltage levels in wind power applications is to use a DC/DC converter or a tap transformer [1][2][3]. Control of a VAWT with PMSG using tip speed ratio control is suggested in [4,5].…”

Experimental Results of a DC Bus Voltage Level Control for a Load-Controlled Marine Current Energy Converter

et al. 2015

This paper investigates three load control methods for a marine current energy converter using a vertical axis current turbine (VACT) mounted on a permanent magnet synchronous generator (PMSG). The three cases are; a fixed AC load, a fixed pulse width modulated (PWM) DC load and DC bus voltage control of a DC load. Experimental results show that the DC bus voltage control reduces the variations of rotational speed by a factor of 3.5 at the cost of slightly increased losses in the generator and transmission lines. For all three cases, the tip speed ratio λ can be kept close to the expected λ opt . The power coefficient is estimated to be 0.36 at λ opt ; however, for all three cases, the average extracted power was about ∼ 19%. A maximum power point tracking (MPPT) system, with or without water velocity measurement, could increase the average extracted power.
