Supercapacitor Internal Resistance Mitigation for Rapid Inertia Emulation of Renewable Power Generation

语言:

中文摘要

利用超级电容器进行惯量仿真(INEC)是提升低惯量电网频率稳定性的有效手段。然而,超级电容器固有的内阻(IR)会降低惯量响应的速度与精度。本文提出了一种针对性的补偿方案,以缓解内阻带来的负面影响,优化可再生能源系统的频率支撑性能。

English Abstract

Inertia emulation control (INEC) using supercapacitors (SC) has become an appealing approach to effectively enhance the frequency stability of modern low-inertia power grids. However, considerable internal resistance (IR) existing in commercially available SCs may adversely degrade the speed and accuracy of SC-based inertial response, which has been neglected by existing INEC schemes. To tackle th...
