A New Data-Driven Distributionally Robust Portfolio Optimization Method Based on Wasserstein Ambiguity Set

open access: yesIEEE Access, 2021
Since optimal portfolio strategy depends heavily on the distribution of uncertain returns, this article proposes a new method for the portfolio optimization problem with respect to distribution uncertainty.

Distributed data-driven distributionally robust Volt/Var control for distribution network via an accelerated alternating optimization procedure

open access: yesEnergy Reports, 2023
This paper proposes a distributed data-driven distributionally robust volt/var control (DDDR-VVC) approach which schedules on-load-tap changer (OLTC), capacitor banks (CBs) and Photovoltaic (PV) inverters coordinately.

Distributionally Robust Portfolio Optimization

open access: yes2019 IEEE 58th Conference on Decision and Control (CDC), 2019
In this paper we consider the problem of portfolio optimization involving uncertainty in the probability distribution of the assets returns. Starting with an estimate of the mean and covariance matrix of the returns of the assets, we define a class of admissible distributions for the returns and show that optimizing the worst-case risk of loss can be ...

Distributionally robust optimization

open access: yesActa Numerica
Distributionally robust optimization (DRO) studies decision problems under uncertainty where the probability distribution governing the uncertain problem parameters is itself uncertain. A key component of any DRO model is its ambiguity set, that is, a family of probability distributions consistent with any available structural or statistical ...

Distributionally Robust Optimization with Probabilistic Group

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2023
Modern machine learning models may be susceptible to learning spurious correlations that hold on average but not for the atypical group of samples. To address the problem, previous approaches minimize the empirical worst-group risk. Despite the promise, they often assume that each sample belongs to one and only one group, which does not allow ...

The Distributionally Robust Optimization Reformulation for Stochastic Complementarity Problems

open access: yesAbstract and Applied Analysis, 2014
We investigate the stochastic linear complementarity problem affinely affected by the uncertain parameters. Assuming that we have only limited information about the uncertain parameters, such as the first two moments or the first two moments as well as ...

Mathematical Foundations of Distributionally Robust Multistage Optimization [PDF]

open access: yesSIAM Journal on Optimization, 2021
Distributionally robust optimization involves various probability measures in its problem formulation. They can be bundled to constitute a risk functional. For this equivalence, risk functionals constitute a fundamental building block in distributionally robust stochastic programming.

Distributionally Robust Distributed Generation Hosting Capacity Assessment in Distribution Systems

open access: yesEnergies, 2018
Uncertainties associated with the loads and the output power of distributed generations create challenges in quantifying the integration limits of distributed generations in distribution networks, i.e., hosting capacity.
