基于负电阻的锂离子电池储能系统电网惯量支撑等效电路模型

Grid-connected lithium-ion battery energy storage system (BESS) plays a crucial role in providing grid inertia support. However, existing equivalent circuit models (ECM) cannot accurately represent the battery's impedance in the inertia support working condition (ISWC). Thus, this article proposes a novel negative resistor-based ECM for BESS in ISWC. First, the principle of grid inertia support of...
