摘要

并网储能系统是大规模采用太阳能光伏发电和风力发电等可再生能源的一项使能技术。作为关键部件，直流开关应可靠地保护储能元件(如电池和超级电容器)免受灾难性故障模式的影响，并提高系统的可用性。然而，储能技术的电学特性对不同的直流分断技术提出了新的挑战和机遇。本文旨在简要概述几种直流破闸技术及其在并网储能系统中的可行性。首先讨论了需求，然后从系统集成的角度对不同的直流分断技术进行了定性比较。最后总结了不同技术面临的技术挑战和机遇。

Survey on DC breaking Technologies for Protection of Grid-connected Energy Storage Systems

Grid-connected energy storage systems are an enabling technology for the massive adoption of renewable energy such as solar PV and wind generation. As key components, the DC switches should reliably protect the energy storage elements, e.g., batteries and ultracapacitors, from catastrophic failure modes and improve system availability. However, the electrical properties of energy storage technologies pose new challenges and opportunities for different DC breaking technologies. This paper aims to give a brief overview of several DC breaking technologies regarding their feasibility in grid-connected energy storage systems. The requirements are firstly discussed, followed by a qualitive comparison among different DC breaking technologies from a system integration perspective. Finally, technical challenges and opportunities for different technologies are summarized.
