    Abstract

    This paper analyzes a sensitivity-based distribution system
    model for the centralized and transparent redispatch of
    distributed flexibilities that obviates the exchange of entire
    distribution models. It allows estimating the impact of
    flexibility activations on the loadings, voltages, and active
    power flows within the distribution network. The responses
    of distribution system controls to flexibility activations are
    not properly reflected by the model parameters and must
    be provided as inputs. A distribution system with many
    renewables is simulated for various cases to analyze the
    model’s accuracy for large flexibility activations. On the
    one hand, results indicate high accuracy of loading and
    active power flow estimations, while on the other hand,
    significant errors are observed in the voltage estimation.
