摘要

惯量水平是影响电力系统频率特性的关键因素，准确评估系统惯量对维持电网频率稳定至关重要。随着储能电池渗透率的提高，其提供的惯量支撑愈发关键，但频繁充放电会加速电池老化，削弱其惯量支撑能力。为此，提出一种考虑储能电池长周期老化效应的电网惯量稳定域(inertia stability region，ISR)评估方法，以防止系统惯量评估虚高导致的频率失稳。该方法首先建立惯量支撑场景下的电池峰值功率衰减模型，分析长期循环造成的功率衰减特性；随后，基于电网频率响应模型，利用功率衰减趋势更新ISR上边界，并结合负荷预测结果确定ISR下边界；最终形成完整ISR，并提出惯量稳定裕度指标。仿真结果表明，该方法能有效反映电池老化对电网惯量水平的影响，为惯量调度提供可靠依据。

Abstract

The inertia level is a key factor affecting the frequency characteristics of power systems

and accurate inertia assessment is essential for maintaining grid frequency stability. With the increasing penetration of battery energy storage systems (BESS)

their contribution to inertia support becomes increasingly critical. However

frequent charge–discharge cycles accelerate battery aging

thereby weakening their inertia-supporting capability. To address this issue

this paper proposes an inertia stability region (ISR) evaluation method that considers the long-term aging effect of BESS to prevent overestimation of system inertia and avoid potential frequency instability. First

a peak power degradation model is established for inertia-supporting scenarios to analyze the long-term degradation characteristics caused by cycling. Then

based on the grid frequency response model

the ISR upper boundary is updated according to the power degradation trend

while the lower boundary is determined using load forecast results. Finally

a complete ISR is formed

and an inertia stability margin index is proposed. Simulation results demonstrate that the proposed method effectively captures the impact of battery aging on grid inertia levels and provides a reliable basis for inertia scheduling.
