Mobile Energy Storage in Power Network: Marginal Value and Optimal Operation
Utkarsha Agwan, Junjie Qin, Kameshwar Poolla +1
This paper examines the marginal value of mobile energy storage, i.e., energy storage units that can be efficiently relocated to other locations in the power network. In particular…
Optimal Ordering Policies for Multi-Echelon Supply Networks
Jose I. Caiza, Ian Walter, Jitesh H. Panchal +2
In this paper, we formulate an optimal ordering policy as a stochastic control problem where each firm decides the amount of input goods to order from their upstream suppliers base…
Electric Vehicle Battery Sharing Game for Mobile Energy Storage Provision in Power Networks
Utkarsha Agwan, Junjie Qin, Kameshwar Poolla +1
Electric vehicles (EVs) equipped with a bidirectional charger can provide valuable grid services as mobile energy storage. However, proper financial incentives need to be in place…
Off-Street Parking for TNC Vehicles to Reduce Cruising Traffic
Sen Li, Junjie Qin, Hai Yang +2
This paper considers off-street parking for the cruising vehicles of transportation network companies (TNCs) to reduce the traffic congestion. We propose a novel business that inte…
The Value of Distributed Energy Resources for Heterogeneous Residential Consumers
Siddharth Patel, Mohammad Rasouli, Junjie Qin +1
The presence of behind-the-meter rooftop photovoltaics and storage in the residential sector is poised to increase significantly. Here we quantify in detail the value of these tech…
Flexible Market for Smart Grid: Coordinated Trading of Contingent Contracts
Junjie Qin, Ram Rajagopal, Pravin Varaiya
A coordinated trading process is proposed as a design for an electricity market with significant uncertainty, perhaps from renewables. In this process, groups of agents propose to…
Control of Generalized Energy Storage Networks
Junjie Qin, Yinlam Chow, Jiyan Yang +1
The integration of intermittent and volatile renewable energy resources requires increased flexibility in the operation of the electric grid. Storage, broadly speaking, provides th…
Weighted Difference Approximation of Value Functions for Slow-Discounting Markov Decision Processes
Yin-Lam Chow, Junjie Qin
Processes (MDPs) often require frequent decision making, that is, taking an action every microsecond, second, or minute. Infinite horizon discount reward formulation is still relev…
Distributed Online Modified Greedy Algorithm for Networked Storage Operation under Uncertainty
Junjie Qin, Yinlam Chow, Jiyan Yang +1
The integration of intermittent and stochastic renewable energy resources requires increased flexibility in the operation of the electric grid. Storage, broadly speaking, provides…
Online Modified Greedy Algorithm for Storage Control under Uncertainty
Junjie Qin, Yinlam Chow, Jiyan Yang +1
This paper studies the general problem of operating energy storage under uncertainty. Two fundamental sources of uncertainty are considered, namely the uncertainty in the unexpecte…
Risk Limiting Dispatch with Ramping Constraints
Junjie Qin, Baosen Zhang, Ram Rajagopal
Reliable operation in power systems is becoming more difficult as the penetration of random renewable resources increases. In particular, operators face the risk of not scheduling…
Risk Limiting Dispatch with Fast Ramping Storage
Junjie Qin, Han-I Su, Ram Rajagopal
Risk Limiting Dispatch (RLD) was proposed recently as a mechanism that utilizes information and market recourse to reduce reserve capacity requirements, emissions and achieve other…
