本文研究分布式和集中式电压控制解决方案在具有高光伏（PV）渗透率的低压（LV）电网中的应用。在传统的低压电网中，分布式光伏转换器和集中式设备的协调需要在新的通信和控制基础设施上进行大量投资。利用分布式光伏转换器的电压控制的替代方案进行了讨论，表明它可以帮助稳定在电网连接点的电压，也没有它们之间的协调和/或与一个集中的单元。本文的目标是研究如何设置光伏逆变器内的电压控制器影响这些控制器的操作，同时考虑到限制无功功率注入。此外，分布式光伏转换器与集中式设备（静态无功补偿器和有载分接开关）的相互作用进行了分析，以评估在这些情况下是否会带来额外的好处。
This paper studies the application of distributed and centralized solutions for voltage control in low voltage (LV) grids with high photovoltaic (PV) penetration. In traditional LV grids, the coordination of distributed PV converters and a centralized device would require massive investments in new communication and control infrastructures. The alternative of exploiting distributed PV converters for voltage control is discussed, showing that it can help to stabilize the voltage in the grid connection points also without coordination between them and/or with a centralized unit. The goal of this paper is to investigate how the setup of the voltage controllers inside PV inverters affects the operation of these controllers taking into account the limits for reactive power injection. In addition, the interaction of distributed PV converters with centralized devices (static var compensators and on load tap changers) is analyzed to assess whether additional benefits may come in these cases.
