中文摘要
随着基于逆变器的可再生能源取代传统同步发电机,电力系统惯量降低。为保障低惯量系统的安全稳定,新标准对分布式光伏(DPV)系统的频率支撑能力提出了更高要求。本文探讨了DPV系统在频率调节和系统恢复中的控制策略,以提升电网稳定性。
English Abstract
Replacing conventional synchronous generator-based power plants with inverter-based renewable energy resources results in a reduction of the inertia in power systems. To sustain the security and reliability of these low-inertia power systems, frequency support is increasingly required in new standards for grid-connected renewable energy resources, especially distributed photovoltaic (DPV) systems....
