Assessing Impact of Uncertainty on a Decision Support System for Flexibility Exploitation in a Distribution Network

In the last years, flexibility markets have been developed in Europe in order to support distribution system operators to manage their systems characterized by a high penetration of distributed generators. The proper exploitation of these market services would require optimization tools for flexibility management as well as a wide set of distributed sensors that should increase network observability. In this context, this work presents an assessment of the effects of measurements uncertainty of distributed monitoring systems on an optimizer of flexibility resources for congestion resolution. The impact of uncertainty of collected measurements is assessed assuming various sets of metering devices, including the so-called “pseudo- measurements” provided by historical data analysis. The performances of the metering infrastructure are evaluated considering the number of congestions solved by the flexibility optimizer. The analyzed case study allows to infer the minimum requirements of a metering infrastructure for support flexibility services.
