technologies, such as solar cells, which harvest energy from sunlight, and triboelectric generators, which produce electricity from human motion. Unfortunately, these devices cannot ensure an efficient power supply for energy storage devices due to the intermittency of sunlight and the low current output of triboelectric electricity. [5][6][7] Moreover, the practical applications of solar cells and triboelectric generators are still limited by their high cost and sophisticated fabrication processes.Among the various sustainable energy sources, wind power is of significant importance due to its universal availability and relatively good continuity, since it exists day and night. [8] Wind power can be easily harvested and converted into efficient electricity by using a low cost winddriven generator (WDG). [9,10] Compared with triboelectric electricity, the electricity produced by wind power delivers high output current and voltage. [11] Recently, the development of wind power harvesting in close conjunction with energy storage has attracted a great deal of research interest. Previous works have focused on integrating WDG with supercapacitors (SCs), due to the fast charging-discharging capability and long cycle life of SCs. [12][13][14] Nevertheless, the key in this field is how to develop the SCs with low electrical resistance, which can reduce energy loss to ensure high conversion efficiency of wind power generation, while well-maintaining high energy density to sufficiently store the harvested energy. [13][14][15] Accordingly, it is more desirable to build a windcharging power system by integrating sustainable wind power harvesting and high-performance SCs with low resistance and high energy density.To meet the demand for portable and wearable electronics, wire-shaped SCs (WSSCs) hold great promise owing to their low weight, tiny volume, and high flexibility. [16][17][18][19] Zhi and coworkers rationally fabricated flexible SCs [20] and WSSCs with shape memory function [21,22] for smart energy storage textiles, as well as built self-powered systems by integrating smart SCs with a photodetector and sensor. [23,24] As we know, carbon fiber Wind power harvesting in conjunction with supercapacitors (SCs) has attracted considerable attention. Nevertheless, the bottleneck in this field is how to develop SCs with low electrical resistance and high energy density.Herein, an ingenious strategy to integrate wind power harvesting and asymmetric wire-shaped SCs (WSSCs) has been put forward for the first time. Remarkably, the asymmetric WSSCs are realized by using vertical FeOOH and CoNi 2 S 4 nanosheet-array-coated flexible carbon fibers as negative and positive yarn electrodes, in which a vertically oriented and cross-linked porous network, formed by electroactive nanosheet arrays, facilitates ionic diffusion and charge transport. Benefiting from an intriguing configuration, these asymmetric WSSCs, with superior flexibility and weavability, act as efficient energy storage devices, which exhibit low resistance, high volumetr...

An improved topology with a fault ride through (FRT) capability when subjected to a DC-link fault-based wind power plant (WPP) employing a Vienna active rectifier-I is proposed in this paper. The proposed system is capable of mitigating fault occurring on the DC-link side using the PWM-controller technique implemented on the Vienna active rectifier. FRT capability analysis is conducted in this paper, simulation results demonstrate the suitability of the control strategy. Actually, use of proposed wind energy conversion unit (WECU) topology has led to the improvement of system stability by maintaining constant output voltage. Furthermore, the WECU integrating Vienna active rectifier-I is also proven as a feasible technology that can be employed in a large-scale WPP or renewable power generations to realize technical and economical efficient grids integration with high voltage direct current (HVDC) transmission systems.

“…From [9], the capacity of fast storage devices such as metaloxide supercapacitors is quite limited and their cost is high, so we a should use them rationally to keep the system within certain levels of fast adjustment ability. In [10], different control methods of batteries on electrical vehicles and their effects on the distribution network were analyzed.…”

Storage devices are indispensable elements in a microgrid to compensate for the power imbalance between loads and the distributed generator (DG) output. Different storage strategies give diverse performances in adjustment speed and capacity. Based on the performance of different storage devices and the features of power imbalance curve in different periods, a classification control strategy is proposed in this paper. First, storage devices are given priorities according to the adjusting speed, and the power imbalance curve is divided into two periods according to the changing speed. During an emergency, all the storages are employed to compensate the rapidly increasing power imbalance; during the steady period, storage device with higher priority is employed to track the instantaneous component of power imbalance, while storage device with lower priority is used to replace the kWh output of higher priority storage. The proposed strategy is tested in a microgrid within the subdistribution network of IEEE RBTS Bus6 system using Monte Carlo methods. Simulation results indicate that the classification control strategy could endow the system with fast adjusting ability through coordination between storages. Reliability indices of the testing system are utilized to demonstrate that the classification control strategy could improve the stability of the microgrid and reliability of the distribution network. © 2015 Institute of Electrical Engineers of Japan.
