This paper proposes a power-leveling method in which a lithium-ion battery and a flywheel energy storage are installed in a photovoltaic power generation plant. The proposed method is a division method that focuses on the amplitude component of the compensating power required to level the generated power of photovoltaic power generation. Furthermore, by adding the flywheel state-of-charge automatic adjustment method to the proposed method, the coverage period of the flywheel is improved. The effectiveness of the proposed method is verified on an actual 40 kW plant.

“…However, in many applications, such as automotive applications where energy is dependent on continually changing engine speed, energy to charge the supercapacitor is only available in a random, uncontrolled manner. Supercapacitors are used as separate balancing systems in energy storage 87,88 and hybrid storage systems 89,90 in a variety of applications (as shown in Figure 11). In the case of wireless‐based applications, efficient systems have been produced by using appropriate supercapacitor charging methods 91,92 .…”

The dependence on renewable energy to solve the major energy issues related to global warming and shortage of energy resources is increasing drastically. This has led to high level awareness of proper energy storage and management. In this regard, supercapacitors have evolved as an efficient energy storage solution and hence successfully employed in several applications. This is attributed to its high-power density, superior performance, and extended maintenance-free lifetime. Also, it is known for low equivalent series resistance, that means, only a small amount of energy is lost while its charging/ discharging even at high current. As a result, it has developed a lot of inquisitiveness among the research community of recent past for further exploration of different aspects of supercapacitors, ranging from material science, modeling and characterizations, engineering applications, and so forth. This review article aims at putting forth an exclusive study of their characterization of supercapacitor for different charging methods and applications. Further, the prime focus is given to the efficiency estimation of supercapacitors which is very essential as it denotes the amount of energy loss or the utilizable state of charge. The analysis has been carried out based on different charging methods and applications, which is essential for improving overall system reliability and performance. The purpose is to organize all important research carried out in this domain till date and to stimulate further insights for effective energy storage and management.

“…In recent years, industrial applications cannot ignore grid disturbances. Large-scale distributed generations (DGs) such as photovoltaic generation and wind power generation, have been implemented in the power grid to conserve energy resources (1) (2) . However, DGs cannot provide stable power supplies because of varying weather conditions, thereby resulting in poor power quality of the power grid.…”

This paper proposes a control method for torque ripple using an open-end winding IPMSM driven by an electrolytic capacitor-less dual inverter under grid disturbances. Under grid disturbances, a conventional motor speed range extension method causes torque ripple due to voltage saturation of the main inverter. The proposed control method achieves both an extension of the motor speed range and a reduction of torque ripple under grid disturbances. The proposed method cancels the harmonic voltage generated due to grid disturbances by the output voltage of the compensating inverter. The effectiveness of the proposed method is verified by experimental results using an electrolytic capacitorless dual inverter and an open-end winding IPMSM under the input voltage distorted by the seventh harmonic voltage. Compared with the conventional method, the proposed method reduces the harmonic currents and the torque ripple by up to 85.6 and 91.0%, respectively, under the distorted input voltage (seventh harmonic, THD 25%). Therefore, the motor drive system using the proposed method can effectively extend the motor speed range, and reducing the torque ripple under grid disturbances.
