DeepOPF-U: A Unified Deep Neural Network to Solve AC Optimal Power Flow in Multiple Networks

no code implementations22 Sep 2023 Heng Liang, Changhong Zhao

The traditional machine learning models to solve optimal power flow (OPF) are mostly trained for a given power network and lack generalizability to today's power networks with varying topologies and growing plug-and-play distributed energy resources (DERs).

Hierarchical Game for Coupled Power System with Energy Sharing and Transportation System

no code implementations27 May 2023 Dongxiang Yan, Tongxin Li, Changhong Zhao, Han Wang, Yue Chen

This necessitates new business models in the power sector to hedge against uncertainties while imposing a strong coupling between the connected power and transportation networks.

Differentially Private Stochastic Convex Optimization in (Non)-Euclidean Space Revisited

no code implementations31 Mar 2023 Jinyan Su, Changhong Zhao, Di Wang

In this paper, we revisit the problem of Differentially Private Stochastic Convex Optimization (DP-SCO) in Euclidean and general $\ell_p^d$ spaces.

AC-Feasible Power Transfer Regions of Virtual Power Plants: Characterization and Application

no code implementations9 Feb 2022 Wei Lin, Changhong Zhao

Distributed energy resources (DERs) in distribution networks can be aggregated as a virtual power plant (VPP) for transmission-level operations.

Cost Functions over Feasible Power Transfer Regions of Virtual Power Plants

no code implementations2 Dec 2021 Wei Lin, Changhong Zhao

To address this challenge, a characterization method is presented in this paper for the intraday operation of a VPP based on the concepts of nonanticipativity and robustness to DERs' uncertainties.

Optimal Energy Scheduling and Sensitivity Analysis for Integrated Power-Water-Heat Systems

no code implementations1 Feb 2021 Sidun Fang, Chenxu Wang, Yashen Lin, Changhong Zhao

The conventionally independent power, water, and heating networks are becoming more tightly connected, which motivates their joint optimal energy scheduling to improve the overall efficiency of an integrated energy system.
