The increasing deployment of utility-scale battery energy storage systems (BESS) necessitates effective strategies for supporting grid services while minimizing degradation that may compromise system longevity. High charge/discharge rates (C-rate) and imbalanced operation of multi-unit BESS configurations may accelerate degradation. This paper proposes a degradation-aware operational optimization based on Model Predictive Control (MPC) for coordinating multiple BESS units under physical and operational constraints. The multi-objective optimization model imposes penalties on C-rate magnitude, operational state-of-charge (SoC) disparity, and battery internal resistance modeled using an equivalent circuit model. A case study conducted for a fleet of BESS units over a one-week load profile …

The Meadow Bank scarp (MBS) in southeastern Illinois is a linear geomorphic expression, ∼10 km long and ∼8 m high above a relatively flat landscape. It parallels an underlying northeast-oriented Late-Precambrian–Early-Cambrian structural fabric, called the Wabash Valley fault zone, and is within an area of modern, historic, and paleo seismicity, called the Wabash Valley seismic zone. In addition, the MBS acts as a boundary of the Wabash River floodplain, as well as Pleistocene glacial outwash channels, which show evidence of frequent outburst flood events. To better understand the MBS’s equivocal origin in this complex geologic environment, we acquired a 917-m-long …

Aims Heart failure with reduced ejection fraction (HFrEF) is a major health problem. Increasing L-type calcium channel (LTCC) activity deteriorates heart function; however, myocardial RRAD knockout (cRADΔ/Δ) instills tonic modulated LTCC current (ICa,L) that preserves healthy myocardium. Thus, we chose to challenge the dogma that enhanced trigger Ca2+ is maladaptive. The study objective was to test the hypothesis that modulated ICa,L in cRADΔ/Δ mice rescues dilated cardiomyopathy by providing tonic modulated trigger Ca2+. Methods and results Mouse and human models were tested. The muscle lim protein knockout mouse (MLPKO) is a murine model of dilated cardiomyopathy (DCM) and HFrEF. The …
