摘要
针对分布式光伏发电并网逆变器在规模化接入电网时面临的电压波动与均衡性问题,文章提出一种基于分层式控制架构与多机协同优化的电压平衡控制技术。通过分析光伏并网逆变器的电压平衡控制原理,结合分层控制、多机协同策略及智能通信网络设计,构建了适应高渗透率光伏场景的动态电压调节体系。通过仿真与实际案例测试,验证该技术在抑制电压波动、提升调节精度及动态响应速度方面的有效性。试验结果表明,所提方案在通信故障和设备参数失配等复杂工况下仍具备较强的鲁棒性,为分布式光伏并网系统的安全稳定运行提供了技术支撑。
In response to the voltage fluctuations and balance issues faced by distributed photovoltaic grid connected inverters when connected to the grid on a large scale,this paper proposes a voltage balance control technology based on a hierarchical control architecture and multi machine collaborative optimization.By analyzing the voltage balance control principle of photovoltaic grid connected inverters,combined with layered control,multi machine collaborative strategy,and intelligent communication network design,a dynamic voltage regulation system suitable for high penetration photovoltaic scenarios was constructed.Through simulation and actual case testing,the effectiveness of this technology in suppressing voltage fluctuations,improving regulation accuracy,and dynamic response speed is verified.The experimental results show that the proposed scheme still has strong robustness under complex working conditions such as communication failures and equipment parameter mismatches,providing technical support for the safe and stable operation of distributed photovoltaic grid connected systems.
