Abstract-With the current increase of distributed generation in distribution networks, line congestions and PQ issues are expected to increase. The smart grid may effectively coordinate DER, only when supported by a comprehensive architecture for automation. In IDE4L project such architecture is designed based on monitoring, control and business use cases. The IDE4L instance of SGAM architecture is derived and explained in details. The automation actor are specified in terms of interfaces, database and functions. The division in these three layers boosted the implementation phase as dedicated interfaces, databases or application has been developed in a modular way and can be installed in different HW/SW. Some implementation instances are presented and the main output of the architecture is discussed with regards to some indexes as communication traffic and level of distribution of automation functions.

“… Derivation of Key Information: This is actually a family of functions including Steady State Model Synthesizer [9], Oscillatory Mode Meter [10], Voltage Stability Analyzer [11], Sub-synchronous Oscillation Detector [12], and Feeder Dynamic Rating [13]. The inputs to all of these functions are curated voltage and current synchrophasors whereas their outputs consist of different number sets in floating point format, often having lower reporting rate compared to that of the synchrophasors.…”

“…The feeder dynamic rating application, developed in this work, acquires data in real-time from weather station (for ambient data), PMU (for line loading), and GPS positioning sensor (for conductor sag) [18]. The application utilizes a Kalman filter to reliably estimate the conductor temperature based upon which the ampacity is computed for each phase of the feeder separately, making the application applicable to distribution grids where unbalances are present.…”

Abstract-Dynamics of distribution grids are becoming more and more complex to analyze due to their transition from passive networks to active ones. This has necessitated the increase of observability between Transmission and Distribution (T&D) grids for operational security and real-time security assessment. This paper presents an overview of the IDE4L project, funded by the European Commission, where a system of PMU data-based monitoring applications has been developed to facilitate TSO-DSO interactions.Index Terms-DSO, dynamic feeder rating, Kalman filter, mode estimator, PMU, steady state model synthesis, TSO, voltage stability analysis.
