二次电池和电池可再生能源储存 - 一般要求和测试方法 - 第2部分:并网应用

[中文适用范围]： IEC 61427 第二部分涉及用于并网型电能存储（EES）应用的二次电池，并提供相关的测试方法，以验证其在这些应用中的耐久性、性能和电气性能。测试方法本质上是电池化学中立性的，即适用于所有类型的二次电池。并网应用的特点是电池通过功率转换设备连接到区域、国家或大陆范围的电网，并作为瞬时能源源和汇，在可再生能源大量随机输入电网时稳定电网性能。相关的功率转换和接口设备不在此部分 IEC 61427 的覆盖范围内。 [外文原描述]： IEC 61427-2:2015 relates to secondary batteries used in on-grid Electrical Energy Storage (EES) applications and provides the associated methods of test for the verification of their endurance, properties and electrical performance in such applications. The test methods are essentially battery chemistry neutral, i.e. applicable to all secondary battery types. On-grid applications are characterized by the fact that batteries are connected, via power conversion devices, to a regional or nation- or continent-wide electricity grid and act as instantaneous energy sources and sinks to stabilize the grids performance when randomly major amounts of electrical energy from renewable energy sources are fed into it. Related power conversion and interface equipment is not covered by this part of IEC 61427.
