p-SWAMP

p-SWAMP (Power Stability Wide Area Monitoring and Protection) is a research and development platform for Wide Area Monitoring, Protection, and Control (WAMPAC). It ingests high-resolution synchrophasor data from Phasor Measurement Units (PMUs), distributes it to independent monitoring applications via a message bus, and provides real-time analysis of transmission grid stability — including electromechanical oscillation detection, islanding detection, voltage stability monitoring, and line outage detection. Results are displayed through interactive 2D and 3D geographic visualizations with an integrated alarm handling system.

As transmission grids absorb more inverter-based resources (wind, solar) and HVDC interconnections, they face new stability challenges: lower system inertia, faster frequency dynamics, and more complex oscillation patterns. Traditional SCADA monitoring operates at second-to-minute timescales and cannot capture these fast-moving phenomena. PMU-based wide-area monitoring provides the millisecond-resolution visibility needed to detect emerging stability issues — but the algorithms, visualization approaches, and architectural patterns for WAMPAC systems are still an active area of research. p-SWAMP provides a shared environment for developing and validating these capabilities before they are transferred to production systems.

p-SWAMP is explicitly a research sandbox, not a production deployment target. Algorithms and approaches validated in p-SWAMP are intended to flow into production tools built by vendors and utilities. The platform is developed by Statnett (the Norwegian TSO) together with research partners SINTEF Energy Research, NTNU, IFE, and Unicus+auticon. It builds on code from the NEWEPS (Nordic Early Warning Early Prevention System) research project (2020–2024). Statnett currently operates approximately 180 PMUs across its transmission grid and uses an existing commercial WAMS for back-office post-analysis; p-SWAMP aims to advance capabilities beyond what commercial systems provide today.
