Abstract

The incremental deployment of small scale stochastic generators has a significant impact low voltage grids. We investigated the applicability of local voltage measurements at household sockets as predictors of the power at the low voltage branch of the transformer. The general goal is to evaluate the feasibility of a decentralized demand-side control algorithm using local voltage as the regulation input. In this paper we introduce the approach adopted by our study and describe the experimental results, which demonstrate the possibility of using a local voltage measurement as an input signal for decentralized control.
