含高比例户用光伏的低压配电网协调控制方法
Coordinated Control Method for Low-Voltage Distribution Networks with High-Penetration Residential Photovoltaic
摘要
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.关键词
