A distribution company energy acquisition market model with integration of distributed generation and load curtailment options
TL;DR: In this paper, the authors presented a novel day-ahead energy acquisition model for a distribution company (DisCo) in a competitive market based on Pool and financial bilateral contracts, where the DisCo purchases active and reactive power according to the offers of DG units, customers, and the wholesale market.
Journal ArticleDOI
Extragradient Method with Variance Reduction for Stochastic Variational Inequalities
TL;DR: This work proposes an extragradient method with stepsizes bounded away from zero for stochastic variational inequalities requiring only pseudomonotonicity, and provides convergence and complexity analysis.

TL;DR: The current status of research on the application of OR methods to forestry and a number of research challenges or open questions that will be of interest to both researchers and practitioners are described.
Journal ArticleDOI
Characterization of lower semicontinuous convex functions
TL;DR: In this paper, it was shown that a lower semicontinuous function defined on a reflexive Banach space is convex if and only if its Clarke subdifferential is monotone.
Journal ArticleDOI
Variational Inequalities and Economic Equilibrium
TL;DR: Variational inequality representations are set up for a general Walrasian model of consumption and production with trading in a market and incorporate Lagrange multipliers for budget constraints, which are shown to lead to an enhanced equilibrium framework with features of collective optimization.
