Normalization of ReLU dual for cut generation in stochastic mixed-integer programs involves reformulating non-anticipativity constraints using ReLU functions to generate tight, non-convex, and mixed-integer representable cuts. Normalizing the dual in the extended space identifies solutions that yield stronger cuts, which are proven to be tight and Pareto-optimal in the original state space. The proposed approach outperforms existing methods by consistently yielding stronger cuts and reducing solution times on harder instances.
The paper proposes a Piecewise Affine (PWA)-based distributed scheme for Model Predictive Control (MPC) that optimizes energy and comfort in large buildings, utilizing Alternating Direction Method of Multipliers (ADMM) for efficient decomposition. The PWA technique is used to handle nonlinear components, and a convex ADMM algorithm transforms the nonconvex problem into smaller convex problems, significantly enhancing computational efficiency. A case study shows that the proposed method reduces execution time by 86% compared to the centralized version.
Researchers have developed a framework called "GPU-to-Grid" that couples device-level GPU control with power system objectives to optimize power consumption and regulation. By using batch size as a control knob, they can trade off voltage impacts against inference latency and token throughput, finding that reducing GPU power consumption alleviates lower voltage limit violations while increasing GPU power mitigates upper voltage limit violations. This challenges the common belief that minimizing GPU power consumption is always beneficial to power grids.
