Control architectures to perform voltage regulation on low voltage networks using DG

Increasing levels of small scale generation units connected to lower voltage levels are causing problems on distribution network operation. The implementation of smart grids enables the operator to have an extended view over the system operational parameters and even to control active participants (loads and generators). Voltage profile volatility is one of the main problems associated with DG units connected to LV networks. The adequate architecture, technical requirements and algorithms for voltage regulation are addressed on this paper.
