Voluntary Renewable Programs: Optimal Pricing and Revenue Allocation
Zhiyuan Fan, Tianyi Lin, Bolun Xu
This paper develops a multi-period optimization framework to design a voluntary renewable program (VRP) for an electric utility company, aiming to maximize total renewable energy d…
Real-time Coordination of Cascaded Hydropower under Decision-Dependent Uncertainty
Eliza Cohn, Ning Qi, Upmanu Lall +1
This study proposes a real-time control framework for cascaded hydropower systems that incorporates decision-dependent uncertainty (DDU) to capture the coupling of streamflow uncer…
Nonparametric Kernel Regression for Coordinated Energy Storage Peak Shaving with Stacked Services
Emily Logan, Ning Qi, Bolun Xu
Developing effective control strategies for behind-the-meter energy storage to coordinate peak shaving and stacked services is essential for reducing electricity costs and extendin…
Online Convex Optimization for Coordinated Long-Term and Short-Term Isolated Microgrid Dispatch
Ning Qi, Yousuf Baker, Bolun Xu
This paper proposes a novel non-anticipatory long-short-term coordinated dispatch framework for isolated microgrid with hybrid short-long-duration energy storages (LDES). We introd…
A Lagrangian-Informed Long-Term Dispatch Policy for Coupled Hydropower and Photovoltaic Systems
Eliza Cohn, Ning Qi, Upmanu Lall +1
This paper presents a long-term dispatch framework for coupled hydropower and floating photovoltaic systems. We introduce a temporal decomposition algorithm based on partial Lagran…
Locational Energy Storage Bid Bounds for Facilitating Social Welfare Convergence
Ning Qi, Bolun Xu
This paper proposes a novel method to generate bid bounds that can serve as offer caps for energy storage in electricity markets to help reduce system costs and regulate potential…
Long-Term Energy Management for Microgrid with Hybrid Hydrogen-Battery Energy Storage: A Prediction-Free Coordinated Optimization Framework
Ning Qi, Kaidi Huang, Zhiyuan Fan +1
This paper studies the long-term energy management of a microgrid coordinating hybrid hydrogen-battery energy storage. We develop an approximate semi-empirical hydrogen storage mod…
Chance-Constrained Energy Storage Pricing for Social Welfare Maximization
Ning Qi, Ningkun Zheng, Bolun Xu
This paper proposes a novel framework to price energy storage in economic dispatch with a social welfare maximization objective. This framework can be utilized by power system oper…
