中文摘要

本文提出了一种用于并网光伏电站的灵活功率点跟踪(FPPT)算法。该算法旨在通过控制光伏阵列的输出功率,实现电网支撑功能。特别是在电压跌落期间,该算法能有效调节光伏组串的输出功率,相比传统FPPT算法具有显著优势,提升了光伏系统在复杂电网环境下的运行灵活性与稳定性。

English Abstract

Flexible power point tracking (FPPT) is the control of active power generated by grid-connected photovoltaic power plants (GCPVPPs) to provide grid-support functionality. An FPPT algorithm for the reduction of the extracted power from photovoltaic (PV) strings during voltage sags was previously proposed by the authors. An advantage of this algorithm, compared to conventional FPPT algorithms, was i...
