摘要

随着户用光伏渗透率的不断提高，低压配电网的电压调节问题日益受到关注。针对不同时间尺度的电压调节需求，提出一种含高比例户用光伏的低压配电网协调控制方法。首先，以网络损耗和电压偏差最小为目标，建立日前-日内集中优化控制模型，求解电压调节资源的运行指令。然后，将户用光伏优化结果应用于实时控制阶段，改进了户用光伏自适应控制策略，根据节点电压量测值动态调节输出功率。最后，对21节点低压配电网算例进行仿真分析，结果表明：所提方法能够显著改善网络损耗和电压分布，并且有效抑制电压越限，保障了低压配电网安全稳定运行。

Abstract

With the continuous increase in the penetration rate of residential photovoltaic (PV)

voltage regulation in low-voltage (LV) distribution networks has attracted growing attention. To address the voltage regulation requirements across different time scales

a coordinated control method for LV distribution networks with high-penetration residential PV is proposed. First

aiming at minimizing network losses and voltage deviation

a day-ahead and intra-day centralized optimization control model is established to determine the operational setpoints for voltage regulation resources. Then

the optimized results for residential PV systems are applied in the real-time control stage

and an adaptive control strategy for residential PV is improved to dynamically adjust the output power based on node voltage measurements. Finally

simulation analysis on a 21-node LV distribution network demonstrates that the proposed method significantly improves network losses and voltage profiles

effectively suppresses voltage violations

and ensures the secure and stable operation of the distribution network.
