“…On the other hand, the research on the power converter is an important link that can effectively solve some bottlenecks and enhance the function. In [17], a novel topology of bidirectional converter applied in FESS was proposed to ensure zero switching power loss, which achieves a saving of power to the extent of 2.5-3.5% and an increase of about 4% in the available backup time. With the development of FESS components, the power density is more than 10 times greater than BESS, and up to 95% round-trip energy efficiency is achieved [8,9].…”

“…Compared with traditional generators, energy storage systems with faster dynamic response capabilities are introduced into LFC, such as, battery [19], ultra-capacitor (UC) [20,21], flywheel energy storage [22], pumped storage [23]. Transient power fluctuations from seconds to minutes can be handled by UC with higher power density, battery with higher energy density can operate for a longer period of time [24,25].…”

Frequency stability is important for microgrid with renewable energy. However, the deterioration of frequency and the increased energy storage equipment are caused by source-load uncertainty. Therefore, a frequency coordinated control strategy based on sliding mode method for a microgrid with hybrid energy storage system (HESS) is proposed. First of all, the detailed frequency regulation is designed, which divides deviation of frequency and area control error into different components as power reference value of different power supply. Secondly, the power threshold of HESS, which is consisted of ultra-capacitor and battery, is set by designed fuzzy controller to reduce reserve power of HESS and avoid unreasonable power output. Thirdly, a load frequency control model with HESS is built and a sliding mode control is designed by using the detailed frequency regulation. Finally, the effectiveness of the proposed frequency coordinated control strategy is verified through comparison of different cases.

“…A voltage doubler cell and coupled inductors are used to obtain the soft switching for a high gain step‐up/step‐down bidirectional dc‐dc converters with minimized voltage stress on the active switches. A zero switching power loss for the boost and buck operation modes of a BDC is measured (or simulated) for flywheel energy storage system using additional silicon‐controlled rectifiers (SCRs) as auxiliary devices along with resonant elements to the main active IGBTs, and the zero voltage/zero current switching operations were achieved under a very low operating frequency of about 15 kHz. A review on DC‐DC converters with the silicon carbide (SiC) active devices is used to show the converter performance.…”

Summary This paper presents a new soft‐switching non‐isolated bidirectional converter (BDC) for the energy storage systems in DC traction. For this proposed converter, the soft commutation is achieved by turning on the main power switches with the help of auxiliary active switches, the inductor, the capacitor, and diodes. The basic operation of the converter is characterized as two operating types: boost and buck. The switching devices obtained zero voltage transition (ZVT) in both operating types, but the major advantage of this topology is achieved by reducing turn‐on losses with improved efficiency and minimizing reverse recovery time of IGBTs' anti‐parallel diodes. This paper mainly describes the principles of operation, design analysis, simulation, and implementation of DC‐DC converter of laboratory prototype with 150 V/250 V system under 1‐kW output power.
