Transmission and Distribution Coordination for DER-rich Energy Markets: A Parametric Programming Approach

no code implementations14 Jun 2023 Mohammad Mousavi, Meng Wu

To compare the proposed framework, an ideal case is defined in which DER aggregators can participate in the wholesale market directly and ISO overseas operation of both transmission and distribution systems.

The FRTB-IMA computational challenge for Equity Autocallables

no code implementations10 May 2023 Mariano Zeron, Meng Wu, Ignacio Ruiz

When the Orthogonal Chebyshev Sliding Technique was introduced it was applied to a portfolio of swaps and swaptions within the context of the FRTB-IMA capital calculation.

Detaching and Boosting: Dual Engine for Scale-Invariant Self-Supervised Monocular Depth Estimation

1 code implementation8 Oct 2022 Peizhe Jiang, Wei Yang, Xiaoqing Ye, Xiao Tan, Meng Wu

Monocular depth estimation (MDE) in the self-supervised scenario has emerged as a promising method as it refrains from the requirement of ground truth depth.

Optimal Utilization of Third-Party Demand Response Resources in Vertically Integrated Utilities: A Game Theoretic Approach

no code implementations25 Jul 2022 Sayyid Mohssen Sajjadi, Meng Wu

The competitions among the EUs in each DR program is captured through a non-cooperative simultaneous game.

ISO and DSO Coordination: A Parametric Programming Approach

no code implementations19 Jan 2022 Mohammad Mousavi, Meng Wu

In this paper, a framework is proposed to coordinate the operation of the independent system operator (ISO) and distribution system operator (DSO) to leverage the wholesale market participation of distributed energy resources (DERs) aggregators while ensuring secure operation of distribution grids.

A Game Theoretic Approach for Demand Response Allocation among Strategic Prosumers in Regulated Distribution Utilities

no code implementations4 Oct 2021 Sayyid Mohssen Sajjadi, Meng Wu

A game theoretic model, consisting of a sequential game coupled with a simultaneous game, is proposed to capture the competition and interaction among PV prosumers, the third-party DR providers, and the utility company.

Multi-Critic Actor Learning: Teaching RL Policies to Act with Style

no code implementations ICLR 2022 Siddharth Mysore, George Cheng, Yunqi Zhao, Kate Saenko, Meng Wu

MultiCriticAL is tested in the context of multi-style learning, a special case of MTRL where agents are trained to behave with different distinct behavior styles, and yields up to 45% performance gains over the single-critic baselines and even successfully learns behavior styles in cases where single-critic approaches may simply fail to learn.

Unmasking the Origin of Kinks in the Photoemission Spectra of Cuprate Superconductors

no code implementations18 Feb 2021 Zhenglu Li, Meng Wu, Yang-Hao Chan, Steven G. Louie

Our results reveal it is the electron density-of-states being the predominant factor in determining the doping-dependence of the kink size, manifesting the multi-band nature of the cuprates, as opposed to the prevalent belief of it being a measure of the mode-coupling strength.
