Abstract
A wide-area grid is a large-scale high voltage power system with regional grids integrated by transmission lines. This work proposes a Wide-Area Stabilization System (WASS) with Phasor Measurement Unit (PMU) sensors and battery converters to mitigate transients in inter-area transmission lines caused by an (N-1) event of line trip. PMU is a measuring device capable of monitoring high voltage buses' magnitude and phase angle in a power grid on a time scale synchronized with a global reference clock. The outreaching time synchronization allows wide-area monitoring of the state of the power system and electrical protection. Three PMU-WASS are modeled on an IEEE 68-buses system and simulated using the YVI Photon++ platform for power system dynamic studies. The results show that the proposed WASS with energy storage avoids the system collapse after line tripping. This research reveals that strict requirements for electrical power converters bring systemic benefits and may be needed ahead of the future large-scale worldwide expansion of electric vehicles fleet.
