Synchrophasor applications facilitating interactions in transmission and distribution operations

Abstract

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.

Impact of non-synchronous generation on transmission oscillations paths

“…The composition of Wide Area Measurement Systems (WAMS) are based on operational tools that are continuously monitoring various signals (e.g., voltages, currents, speed of machines) in the grid. The inclusion of distributed Phasor Measurement Units (PMUs) in the system has allowed to transmit, process and comprehend these signals in order to improve and protect the system to undersirable events [1].…”

City-Friendly Smart Network Technologies and Infrastructures: The Spanish Experience

“…These involve voltage and frequency regulation, including reserve generation. In a context where part of the generation is migrating from the TSO to the DSO domains, the EMS/DMS coordination, entailing exchanges of information, models and coordinated controls at the interface, becomes more crucial[121]-[124].• Moreover, a new generation of state estimation, security analysis, and related preventive and corrective tools must be devised, taking advantage of increased bandwidths of communication channels, smarter measuring (PMUs), and protection devices (IEDs), providing many more data at much faster rates, and new standards for transmission substations (e.g., IEC 61850). • New EMS must allow TSO/ISOs to interact with the power plant controllers (PPCs) of large, centralized renewable facilities, steadily gaining quota in the energy mix, which are becoming more and more flexible and controllable with the help of storage assets.A successful example is the add-on center (CECRE) developed in Spain by REE [125].…”
