An Unsupervised Deep Learning Approach for Scenario Forecasts
Yize Chen, Xiyu Wang, Baosen Zhang
In this paper, we propose a novel scenario forecasts approach which can be applied to a broad range of power system operations (e.g., wind, solar, load) over various forecasts hori…
Non-Wire Alternatives to Capacity Expansion
Jesus E. Contreras-Ocaña, Uzma Siddiqi, Baosen Zhang
Distributed energy resources (DERs) can serve as non-wire alternatives to capacity expansion by managing peak load to avoid or defer traditional expansion projects. In this paper,…
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…
Uncertainty in Multi-Commodity Routing Networks: When does it help?
Shreyas Sekar, Liyuan Zheng, Lillian J. Ratliff +1
We study the equilibrium behavior in a multi-commodity selfish routing game with many types of uncertain users where each user over- or under-estimates their congestion costs by a…
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…
An Online Optimization Algorithm for Alleviating Contingencies in Transmission Networks
Nicolo Mazzi, Baosen Zhang, Daniel S. Kirschen
Power systems are increasingly operated in corrective rather than preventive security mode, which means that appropriate control actions must be taken immediately after a contingen…
Participation of an Energy Storage Aggregator in Electricity Markets
Jesus E. Contreras-Ocana, Miguel A. Ortega-Vazquez, Baosen Zhang
An important function of aggregators is to enable the participation of small energy storage units in electricity markets. This paper studies two generally overlooked aspects relate…
Linear Estimation of Treatment Effects in Demand Response: An Experimental Design Approach
Pan Li, Baosen Zhang
Demand response aims to stimulate electricity consumers to modify their loads at critical time periods. In this paper, we consider signals in demand response programs as a binary t…
