Cross-attention-based hybrid feature fusion network for state-of-health estimation of lithium-ion batteries

Scientific Reports
Estimating the state of health (SOH) of lithium-ion batteries (LIBs) is crucial in a battery management system. To improve the accuracy of SOH estimation, a new method that combines a Gramian angle field (GAF) and multi–model fusion is proposed.

Decoupled damping torque coefficient of equivalent heterogeneous wind farm for power system low-frequency oscillation analysis

International Journal of Electrical Power & Energy Systems
With increasing integration of doubly-fed induction generators (DFIGs), the inertia provided by synchronous generators (SGs) reduces, thus power system low-frequency oscillation (LFO) will be intensified. The virtual synchronous generator (VSG) installed

Saving Water Saves Energy

, 2006
Hot water use in households, for showers and baths as well as for washing clothes and dishes, is a major driver of household energy consumption. Other household uses of water (such as irrigating landscaping) require additional energy in other sectors to transport and treat the water before use, and to treat wastewater.
