Graphical abstract of the proposed decision‐aware Neural TTC framework. AC‐secure TTC labels are first generated from spatio‐temporal operating conditions using CPF/RPF and N‐1 screening with thermal, voltage, and transient security checks. A compact ReLU neural surrogate then maps exogenous conditions and endogenous dispatch decisions to interface TTC,

Presolving convexified optimal power flow with mixtures of gradient experts
Convex relaxations and approximations of the optimal power flow (OPF) problem have gained significant research and industrial interest for planning and operations in electric power networks. One approach for reducing their solve times is presolving which

An adaptive chance‐constrained hybrid SOCP‐Based ACOPF for coordinated optimisation of integrated source–grid–load–storage systems is presented. The coordinated optimisation of integrated source–grid–load–storage (SGLS) systems is challenged by renewable energy uncertainty, complex industrial load characteristics and stringent policy constraints ...

Abstract In this proof‐of‐concept study, we evaluated the feasibility of non‐invasive estimation of cardiac power metrics—total power, steady power, oscillatory power, and oscillatory power fraction—and compared the prognostic and diagnostic value with established echocardiographic metrics. We prospectively included 29 patients (mean age 76 ± 13 years,

Moment-Based Relaxation of the Optimal Power Flow Problem
The optimal power flow (OPF) problem minimizes power system operating cost subject to both engineering and network constraints. With the potential to find global solutions, significant research interest has focused on convex relaxations of the non-convex

Diagnostic analytics of electricity tariff design in Nepal
Abstract Nepal's electricity sector operates under a monopsony, with government entities dominating generation, transmission, and distribution. This market structure suppresses competition, leading to inherent challenges in establishing fair and efficient electricity tariff systems.
