| Resumo | |
The growing deployment of Phasor Measurement Units (PMUs) in Electric Power Systems (EPSs) has led status measurements from switchable devices to be transmitted at high sampling rates, enabling rapid detection of switching events and continuous topology updates. Fast topology processing is therefore essential for reliable operation and decision-making in modern, dynamic EPSs. In this context, this paper proposes an Algebraic Tracking Network Topology Processor (AT-NTP) developed from algebraic formulations and a new islanding identification method. Using status measurements from PMUs and other sources, AT-NTP determines and updates network topologies through matrix factorization and refactorization, avoiding graph search algorithms and artificial intelligence techniques commonly used in existing topology processors. It is simple to implement, avoids combinatorial explosion, does not require training stages, and efficiently detects switching events, island formation, bus merging or splitting, and measurement configuration changes without recomputing the topology from scratch. Its formulation applies to arbitrary substation configurations requiring no adaptations, which makes it flexible and suitable for various systems. Simulation results on benchmark and large-scale real networks demonstrated its computational efficiency and confirmed its suitability for PMU-based state estimation and advanced energy management applications.
