“…The output power to weight ratio of an 8 MW FSDD is about 2 times of a conventional geared with double fed induction generator (DFIG) wind turbine. Presently, there are several companies which are exploring large superconducting (SC) generators for offshore wind systems [25]. These include American Superconductor (AMSC-10 MW), Converteam (8 MW) now owned by GE, China-TECO Westinghouse (5 MW), China Sinovel (5 MW), Advanced Magnet Lab (AML-10 MW), and GE (10-15 MW) [26]- [28].…”

This paper focuses on a review of the state of the art of future power grids, where new and modern technologies will be integrated into the power distribution grid, and will become the future key players for electricity generation, transmission, and distribution. The current power grids are undergoing an unprecedented transformation from the original design, changing the way how energy has been produced, delivered, and consumed over the past century. This new energy era includes the integration of renewable sources such as wind and solar, supported by the distributed or community energy storage, to power distribution grids through innovative high-frequency magnetic links and power-electronic converters. The use of emission free transportation, such as electric vehicles, and energy efficient technologies, such as superconducting generators and storage systems, are also rapidly emerging and will be integrated into the power grids in the foreseeable future. However, it is necessary to reconsider the current paradigms of system analysis and plan with a focus on how to achieve the most flexible, efficient, and reliable power grid for the future-the one that enables operation in a domain which is very different than the current one to deliver the services to consumers at an affordable cost.

“…Their main drawbacks are larger ohmic losses in their DC inductors and heavy inductor cores. Nevertheless, ongoing research in the field of High Temperature Superconductors (HTS) has yielded promising results [5][6][7]. In [6], utilizing HTS coils was shown to reduce a generator's losses and weight by half and one third, respectively.…”

In high power, medium voltage applications, Current Source Inverters CSIs are connected in parallel to accommodate high DC currents. Using a proper multilevel modulation technique, parallel-connected CSIs can operate as a Multilevel CSI (MCSI). The most common modulation technique for MCSIs is the Phase-Shifted Carrier SPWM (PSC-SPWM). The proper operation of the MCSI requires each CSI modules to have the same average current flowing through its sharing inductors. In practice, the average currents of the CSI modules deviate from their nominal values. Therefore, current balancing mechanisms must be implemented. In the literature, several solutions have been proposed to tackle the current imbalance problem. Most of these solutions are based on altering the phase-shift or magnitude of the carrier waveforms of the PSC-SPWM. They require dedicated PI controllers and they are applicable to MCSIs with specific numbers of levels. This paper proposes a Current Balancing Algorithm (CBA) that can be implemented in any MCSI with any number of levels. The proposed CBA does not require any PI controllers, nor does it require any alteration to the PWM carrier waveforms. The CBA is implemented using a modified Level-Shifted SPWM (LS-PWM). The modified LS-SPWM is shown to produce lower THD and lower di/dt when compared to the PSC-SPWM. The CBA and modified LS-SPWM where implemented in a proof-of-concept lab prototype. The experimental results are presented for the five-level and seven-level cases.

With the development of advanced soft magnetic materials of high saturation flux density and low specific core loss and semiconductor power devices, the high frequency transformer (HFT) has received significant attentions in recent years for its widespread emerging applications. The optimal design of high power density HFTs for high performance energy conversion systems, however, is a multiphasic problem that needs special considerations on various aspects such as core material selection, minimization of parasitic components and thermal management. This paper presents a comprehensive review on advancement of soft magnetic materials for high power density magnetic devices and advanced technologies for characterizations and optimal design of HFTs. The future research and development trends are also discussed.
