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…
Arbitraging Variable Efficiency Energy Storage using Analytical Stochastic Dynamic Programming
Ningkun Zheng, Joshua Jaworski, Bolun Xu
This paper presents a computation-efficient stochastic dynamic programming algorithm for solving energy storage price arbitrage considering variable charge and discharge efficienci…
Dynamic Valuation of Battery Lifetime
Bolun Xu
This paper proposes a dynamic valuation framework to determine the opportunity value of battery capacity degradation in grid applications based on the internal degradation mechanis…
Optimal Battery Participation in Frequency Regulation Markets
Bolun Xu, Yuanyuan Shi, Daniel S. Kirschen +1
Battery participants in performance-based frequency regulation markets must consider the cost of battery aging in their operating strategies to maximize market profits. In this pap…
Optimal Battery Control Under Cycle Aging Mechanisms in Pay for Performance Settings
Yuanyuan Shi, Bolun Xu, Yushi Tan +2
We study the optimal control of battery energy storage under a general "pay-for-performance" setup such as providing frequency regulation and renewable integration. In these settin…
Factoring the Cycle Aging Cost of Batteries Participating in Electricity Markets
Bolun Xu, Jinye Zhao, Tongxin Zheng +2
When participating in electricity markets, owners of battery energy storage systems must bid in such a way that their revenues will at least cover their true cost of operation. Sin…
A Convex Cycle-based Degradation Model for Battery Energy Storage Planning and Operation
Yuanyuan Shi, Bolun Xu, Yushi Tan +1
A vital aspect in energy storage planning and operation is to accurately model its operational cost, which mainly comes from the battery cell degradation. Battery degradation can b…
Optimal Regulation Response of Batteries Under Cycle Aging Mechanisms
Bolun Xu, Yuanyuan Shi, Daniel S. Kirschen +1
When providing frequency regulation in a pay-for-performance market, batteries need to carefully balance the trade-off between following regulation signals and their degradation co…
Impact of Local Transmission Congestion on Energy Storage Arbitrage Opportunities
Yishen Wang, Yury Dvorkin, Ricardo Fernández-Blanco +2
Reduced installation and operating costs give energy storage systems an opportunity to participate actively and profitably in electricity markets. In addition to providing ancillar…
Impact of Dynamic Line Rating on Dispatch Decisions and Integration of Variable RES Energy
Bolun Xu, Andreas Ulbig, Goran Andersson
Dynamic line rating (DLR) models the transmission capacity of overhead lines as a function of ambient conditions. It takes advantage of the physical thermal property of overhead li…
Scalable Planning for Energy Storage in Energy and Reserve Markets
Bolun Xu, Yishen Wang, Yury Dvorkin +4
Energy storage can facilitate the integration of renewable energy resources by providing arbitrage and ancillary services. Jointly optimizing energy and ancillary services in a cen…
A Comparison of Policies on the Participation of Storage in U.S. Frequency Regulation Markets
Bolun Xu, Yury Dvorkin, Daniel S. Kirschen +2
Because energy storage systems have better ramping characteristics than traditional generators, their participation in frequency regulation should facilitate the balancing of load…
