随着新能源发电技术的不断发展,接纳这些分布式电源的微电网也日益壮大,但分布式电源的输出功率具有间歇性且随机性强,影响微电网的运行及电能质量等。为了增强微电网的运行稳定性及供电质量,将储能系统应用到微电网结构中。而单一的储能系统已经不能满足微电网的需求,因此采用超级电容器和多硫化物溴电池(PSB)混合储能系统,利用超级电容的快速响应和功率密度大等特性快速填补微电网的功率缺失,当需要长时间提供电能时则由PSB来填补。超级电容器与PSB组成的混合储能系统兼具功率型和能量型储能元件的优点,可以更好的发挥储能系统在微电网中的作用。 相似文献

Growing demands on energy storage devices have inspired a tremendous amount of research on rechargeable batteries. Future generations of rechargeable batteries are required to have high energy density, long lifespan, low cost, high safety, low environmental impact, and wide commercial affordability. To achieve these goals, significant efforts are underway to focus on electrolyte chemistry, electrode engineering, and new designs for energy storage systems. Herein, a comprehensive overview of an innovative sodium-based hybrid metal-ion battery (HMIBs) for advanced next-generation energy storage is presented. Recent advances on sodium-based HMIBs from the development of reformulated or novel materials associated with Na+ ions and other metal ions (such as Li+, K+, Mg2+, Zn2+, etc.), are summarized in this work. Daniell cell and “rocking-chair” type batteries are covered. Finally, the current challenges and future remedies in terms of the design and fabrication of new electrolytes, cathodes, and anodes for advanced HMIBs are discussed in this report. 相似文献

Flexible Integrated Electrical Cables Based on Biocomposites for Synchronous Energy Transmission and Storage 下载免费PDF全文

It becomes increasingly important to develop integrated systems with the aim of achieving maximum functionality for the state‐of‐the‐art electronic devices. Here, a flexible integrated electrical cable is reported by incorporating biomaterials based fiber supercapacitors into a resistor–capacitor circuit. In this unique integrated configuration, the fiber electrodes are alternately winded along the twisted electric wires, which worked not only as scaffolding to support and strengthen the slight electrodes but also as separators to spatially confine them to avoid short circuit. It exhibits excellent electrochemical performance comparable to conventional transition metal compounds based cells, and can especially realize sophisticated applications in synchronous energy transmission and storage, presenting a new member for the integrated energy storage system family. 相似文献

The wind energy generation,utilization and its grid penetration in electrical grid are increasing world-wide.The wind generated power is always fluctuating due to its time varying nature and causing stability problem.This weak interconnection of wind generating source in the electrical network affects the power quality and reliability.The localized energy storages shall compensate the fluctuating power and support to strengthen the wind generator in the power system,in this paper,it is proposed to control the voltage source inverter(VSI)in current control mode with energy storage,that is,batteries across the dc bus.The generated wind power can be extracted under varying wind speed and stored in the batteries.This energy storage maintains the stiff voltage across the dc bus of the voltage source inverter.The proposed scheme enhances the stability and reliability of the power system and maintains unity power factor,it can also be operated in stand-alone mode in the power system.The power exchange across the wind generation and the load under dynamic situation is feasible while maintaining the power quality norms at the common point of coupling.It strengthens the weak grid in the power system.This control strategy is evaluated on the test system under dynamic condition by using simulation.The results are verified by comparing the performance of controllers. 相似文献
