摘 要
随着全球能源转型的加速，光伏发电作为重要的可再生能源形式，在配电网中的渗透率持续提升。然而，高渗透率光伏接入对配电网电压稳定性带来了显著挑战，传统电压控制方法难以满足复杂场景下的调控需求。为此，本文旨在研究适用于高渗透率光伏接入条件下的配电网电压控制策略。通过构建含分布式光伏的配电网模型，结合动态潮流分析，提出了一种基于多源协同优化的电压控制框架。该框架综合考虑逆变器无功调节、储能系统动态响应以及有载调压变压器的协调作用，并引入分层分区控制算法以提高控制效率与灵活性。仿真结果表明，所提策略能够有效抑制电压越限问题，显著改善配电网运行性能，同时降低系统损耗。

ABSTRACT
With the acceleration of the global energy transition, photovoltaic power generation, as an important form of renewable energy, the penetration rate in the distribution network continues to increase. However, the high penetration of photovoltaic access brings significant challenges to the voltage stability of the distribution network, and the traditional voltage control methods are difficult to meet the regulation requirements in complex scenarios. To this end, this paper aims to study the voltage control strategy of distribution network suitable to high permeability photovoltaic access conditions. By constructing a distribution network model with distributed photovoltaic and combining with dynamic power flow analysis, a voltage control fr amework based on multi-source collaborative optimization is proposed. The fr amework comprehensively considers the reactive power regulation of inverter, the dynamic response of energy storage system and the coordination of on-load voltage regulating transformer, and introduces the hierarchical partition control algorithm to improve the control efficiency and flexibility. The simulation results show that the proposed strategy can effectively suppress the voltage limit, improve the performance of distribution network and reduce the system loss.
