Abstract
This paper examines the challenges of integrating a Decision Support System for Flexibility Exploitation (DSSFE) into distribution networks. The study systematically addresses uncertainties arising from heterogeneous monitoring infrastructures and from the knowledge of the network parameters, such as line impedances. The impact on a DSSFE application of sensor accuracy (i.e., high/medium accuracy and/or pseudo-measurements), different placement of the sensors in the nodes of the network and the uncertainty in the knowledge of the network parameters is extensively evaluated by means of a stochastic approach. Key figures of merit, such as false positives, false negatives, and residual congestions, are defined to quantify DSSFE performance. The analysis offers insights into infrastructure design trade-offs and on the achievable performance of DSSFE applications.
