Optimal Placement of PMU for Power System Observability

International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering, 2014
Phasor Measurement Unit (PMU) is a relatively new technology that, when employed in power networks, offers real-time synchronised measurements of the voltages at buses and currents along the lines that connect them. This is accomplished by using a GPS based monitoring system which facilitates time synchronisation of measurements and unlike SCADA, makes

Morphotropic Phase Boundary Engineering via Heterostructure for Low‐Voltage Ferroelectric Capacitors

Advanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
Morphotropic phase boundary engineering in HfxZr1‐xO2 heterostructures enables low‐voltage and fast ferroelectric switching. This layer promotes polarization switching near 0 V, resulting in ≈25% reduction in coercive voltage and enhanced capacitance. This heterostructure design provides a practical route for energy‐efficient ferroelectric capacitors ...
