Using Micro-Synchrophasor Data for Advanced Distribution Grid Planning and Operations Analysis

摘要: Author(s): Stewart, Emma; Kiliccote, Sila; McParland, Charles; Roberts, Ciaran | Abstract: This report reviews the potential for distribution-grid phase-angle data that will be available from new micro-synchrophasors (µPMUs) to utilized in existing planning and operations analysis. could augment current diagnostic capabilities of grid analysis software, used both applications such as fault location, provide more accurate modeling distribution system. µPMUs are sensors advance measurement improved visibility grid, enabling grid’s increasingly complex loads include features large volumes distributed generation. Large DG leads concerns on continued reliable operation due changing power flow characteristics active generation, with its own protection control capabilities. Using µPMU change voltage phase angle between two points conjunction operational tools is expected enable model validation, state estimation, renewable resource/load characterization. Our findings include: outstripping processing tools; not every tool can visualize a degree accuracy measured by advanced sensors, required defined; solving methods cannot handle high generated modern so models (such graph trace analysis) needed; standardization sensor-data communications platforms would allow integration different vendors’ devices. In addition, sources validate improve/ensure accuracy, providing information normally estimated values underground conductor impedance, characterization loads. Although input high-fidelity challenging, (as well other sensors) useful basic decisions based trend data.
