These days, due to distributed generation increasing, the operation and control of active distribution grid becomes complicated. Thus, their voltage control is the main topic of many research papers recently. While network reinforcement mitigated voltage rise in passive distribution networks, local voltage control, coordinated voltage control and centralized voltage control have been studied in several research papers. However, many of these approaches need plenty of sensors to gather large number of measurements that could cause complexity. This paper presents a new procedure to set up a local voltage control law devoted to properly manage the voltage profile (e.g. minimizing losses on MV feeders and increasing grid hosting capacity), without relying on advanced telecommunication architectures. The final goal of this paper is in a procedure that could be directly adopted in the today in place electric distribution grids. In particular, the contribution proposed is a method to optimize, offline, the $Q\left(V\right)$ characteristic curve of the local voltage control for distributed generation units. The approach proposed has been implemented and tested on a real-life distribution grid of an Italian mountain area, where overvoltage problems could seriously bound renewable exploitation.

近年来，由于分布式发电的增加，有源配电网的操作和控制变得复杂。因此，它们的电压控制是最近许多研究论文的主题。尽管网络加固可以缓解无源配电网中的电压升高，但几篇研究论文已经对局部电压控制，协调电压控制和集中电压控制进行了研究。但是，这些方法中的许多方法都需要大量传感器来收集可能导致复杂性的大量测量。本文提出了一种新的程序，用于建立本地电压控制法则，该法则专门用于适当地管理电压曲线（例如，使MV馈线的损耗最小化并增加电网承载能力），而无需依赖先进的电信体系结构。本文的最终目标是采用一种程序，该程序可以在当今的配电网中直接采用。特别是，建议的贡献是一种离线优化广告资源的方法$问（V）$分布式发电机组局部电压控制的特性曲线。提议的方法已在意大利山区的实际配电网中实施和测试，该地区的过电压问题可能严重限制可再生能源的开发。
