储能系统与电网
可靠的储能系统通过补充峰值容量需求和使用微电网或分布式储能，使电网受益。电网储能系统运营商必须确保电网在高峰期有足够的能量来满足需求。电池储能系统（BESS）收集能量并根据需要释放能量，可以在用电高峰期作为备用。这样就不需要增加整体的能源发电能力来满足极端需求。
分布式储能允许使用微电网在本地范围内建立更小、更有效的配电网络。这些微电网可以自主运作，也可以作为一个更大的电网系统的一部分。它们需要能源发电来源（通常是太阳能和风能等可再生能源）和大型电池组来储存能量。分布式储能系统。
- 为可再生能源发电提供支持
- 允许频率调节并改善电能质量
- 负荷转移，这样就可以在成本低的时候储存电力，在成本高的时候释放电力
- 在停电期间提供备用电源。

电网存储应用的电池测试
电池是储能系统中决定特定工作条件下性能的关键部件。重要的是，电池要为其使用寿命内的负载、温度条件和持续时间提供足够的能量。电池制造商为其电池或模块的性能提供一般规格，但这些需要结合具体的应用参数来评估。
典型的性能指标将包括各种条件下的放电性能、峰值放电电流、内阻、耐久循环、能源效率指标等。这些指标将作为评估电网存储系统中不同类型电池的基线性能比较。
再生性（回网）测试
Arbin users state-of-the-art regenerative circuitry for all high-voltage/high-power applications. Energy storage systems for grid-scale applications commonly need to be tested at 100s of kW. Arbin’s regenerative “RBT” test equipment provides a range of 2.5kW to 1MW of power. High-efficiency circuitry and power density minimize the cost of operation compared to similar equipment.
- 功率因数 > 0.99
- 再生效率 > 92%
与机架安装的电子负载+电源解决方案相比，Arbin的完全集成的交钥匙系统具有更好的性能和更安全的操作。
- 控制精度< 0.05$（行业领先）。
- 每个通道有多个电流范围
- 电流上升时间 < 10ms
- 10ms的同步数据记录
- 可选的辅助输入可由用户完全定制，并可在任何配置中与主I/V通道灵活地映射。所有数据都被整合到一个单一的Arbin数据库中。
Thermal Safety and Arbin’s Battery Test Equipment
Thermal safety is a key factor that can affect battery stability and safety. Grid storage systems are often located outdoors and are thus exposed to the elements and changes in weather and ambient temperature. Arbin has created an innovative new temperature chamber for testing individual cells known as the “MZTC” Multi-Chamber.
This cell-isolating battery test chamber isolates each cell or pair of cells (depending on cell size and amperage) to create a safer test environment and maintain greater temperature stability. Each of the 8 mini-chambers offers a unique temperature setpoint and is thermally isolated from the others to prevent thermal run-away or cascading failure events. Arbin’s MZTC battery test chamber also makes connections and interfacing with cells easy.
Arbin还可以选择与其他制造商的各种第三方温度室接口。该软件与世界上大多数主要的试验室控制器型号兼容，因此Arbin试验箱可以自动打开和关闭试验室，并在试验期间调整温度。
当系统的安全性能够得到保证时，电网储能系统将得到越来越广泛的采用。电池测试设备必须帮助确定电池可以安全运行的参数，同时也要保持一个安全的测试环境。
