Stochastic optimization for the scheduling of a grid-connected microgrid with a hybrid energy storage system considering multiple uncertainties

open access: yesEnergy Reports, 2022
The deployment of a microgrid with renewable energy sources (RESs) generally considers two aspects i.e., the need for the energy storage and the presence of many uncertainties due to the intermittent nature of several RESs and the load demand variability.

Quantitative Stability of Optimization Problems with Stochastic Constraints

open access: yesMathematics, 2023
In this paper, we consider optimization problems with stochastic constraints. We derive quantitative stability results for the optimal value function, the optimal solution set and the feasible solution set of optimization models in which the underlying ...

Numerical techniques for stochastic foot and mouth disease epidemic model with the impact of vaccination

open access: yesAdvances in Difference Equations, 2020
The spread of an epidemic diseases is stochastic in nature. It is more realistic to include this stochasticity when modelling the dynamics of a communicable disease.

A Stochastic Multiobjective Optimization Framework for Wireless Sensor Networks

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
In wireless sensor networks (WSNs), there generally exist many different objective functions to be optimized. In this paper, we propose a stochastic multiobjective optimization approach to solve such kind of problem.

Optimal Stochastic Planarization [PDF]

open access: yes2010 IEEE 51st Annual Symposium on Foundations of Computer Science, 2010
It has been shown by Indyk and Sidiropoulos [IS07] that any graph of genus g>0 can be stochastically embedded into a distribution over planar graphs with distortion 2^O(g). This bound was later improved to O(g^2) by Borradaile, Lee and Sidiropoulos [BLS09]. We give an embedding with distortion O(log g), which is asymptotically optimal.

Stochastic programming with multivariate second order stochastic dominance constraints with applications in portfolio optimization [PDF]

open access: yes, 2014
In this paper we study optimization problems with multivariate stochastic dominance constraints where the underlying functions are not necessarily linear. These problems are important in multicriterion decision making, since each component of vectors can

K-adaptability in stochastic optimization [PDF]

open access: yesMathematical Programming, 2022
AbstractWe consider stochastic problems in which both the objective function and the feasible set are affected by uncertainty. We address these problems using a K-adaptability approach, in which K solutions for a given problem are computed before the uncertainty dissolves and afterwards the best of them can be chosen for the realized scenario.

Double-uncertainty optimal operation of hybrid AC/DC microgrids with high proportion of intermittent energy sources

open access: yesJournal of Modern Power Systems and Clean Energy, 2017
This paper applies double-uncertainty optimization theory to the operation of AC/DC hybrid microgrids to deal with uncertainties caused by a high proportion of intermittent energy sources.
