We investigate competitive online algorithms for online convex optimization (OCO) problems
with linear in-stage costs, switching costs and ramp constraints. While OCO problems have …

There has been significant interest in leveraging limited look-ahead to achieve low
competitive ratios for online convex optimization (OCO). However, existing online algorithms …

Dynamic Security Assessment (DSA) is critical for maintaining stability in large-scale smart
grids, especially with the growing integration of renewable energy sources and the inherent …

NOTICE OF RETRACTION:" On the Value of Look-Ahead in Competitive Online Convex
Optimization," by Shi et al., Proceedings of the ACM on Measurement and Analysis of …

Recent studies have shown that power-proportional data centers can save energy cost by
dynamically “right-sizing” the data centers based on real-time workload. More servers are …

In this article, we develop online multistage decisions for procuring and dispatching
generators with diverse capabilities to provably ensure reliability of power grid operations …

The uncertainty and variability of renewable generation pose significant challenges to
reliable power-grid operations. This paper designs robust online strategies for jointly …

We study cloud resource control in the global-local distributed cloud infrastructure. We firstly
model and formulate the problem while capturing the multiple challenges such as the inter …

Online decision making with switching costs has received considerable attention in many
practical problems that face uncertainty in the inputs and key problem parameters. Because …

We consider a time-varying optimization approach to the target tracking problem.
Specifically, we apply online gradient descent (OGD) to a sequence of loss functions …
