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…
Comparative Withholding Behavior Analysis of Historical Energy Storage Bids in California
Neal Ma, Ningkun Zheng, Ning Qi +1
The rapid growth of battery energy storage in wholesale electricity markets calls for a deeper understanding of storage operators' bidding strategies and their market impacts. This…
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…
Energy Storage Arbitrage in Two-settlement Markets: A Transformer-Based Approach
Saud Alghumayjan, Jiajun Han, Ningkun Zheng +2
This paper presents an integrated model for bidding energy storage in day-ahead and real-time markets to maximize profits. We show that in integrated two-stage bidding, the real-ti…
A WECC-based Model for Simulating Two-stage Market Clearing with High-temporal-resolution
Ningkun Zheng, Bolun Xu
This paper presents a new open-source model for simulating two-stage market clearing based on the Western Electricity Coordinating Council Anchor Data Set. We model accurate two-st…
Predicting Strategic Energy Storage Behaviors
Yuexin Bian, Ningkun Zheng, Yang Zheng +2
Energy storage are strategic participants in electricity markets to arbitrage price differences. Future power system operators must understand and predict strategic storage arbitra…
Vehicle-to-Grid Fleet Service Provision considering Nonlinear Battery Behaviors
Joshua Jaworski, Ningkun Zheng, Matthias Preindl +1
The surging adoption of electric vehicles (EV) calls for accurate and efficient approaches to coordinate with the power grid operation. By being responsive to distribution grid lim…
Transferable Energy Storage Bidder
Yousuf Baker, Ningkun Zheng, Bolun Xu
Energy storage resources must consider both price uncertainties and their physical operating characteristics when participating in wholesale electricity markets. This is a challeng…
Energy Storage Price Arbitrage via Opportunity Value Function Prediction
Ningkun Zheng, Xiaoxiang Liu, Bolun Xu +1
This paper proposes a novel energy storage price arbitrage algorithm combining supervised learning with dynamic programming. The proposed approach uses a neural network to directly…
Energy Storage State-of-Charge Market Model
Ningkun Zheng, Xin Qin, Di Wu +2
This paper introduces and rationalizes a new model for bidding and clearing energy storage resources in wholesale energy markets. Charge and discharge bids in this model depend on…
Impact of Bidding and Dispatch Models over Energy Storage Utilization in Bulk Power Systems
Ningkun Zheng, Bolun Xu
Energy storage is a key enabler towards a low-emission electricity system, but requires appropriate dispatch models to be economically coordinated with other generation resources i…
