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…
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…
Spatial Pricing in Ride-Sourcing Markets under a Congestion Charge
Sen Li, Hai Yang, Kameshwar Poolla +1
This paper studies the optimal spatial pricing for a ride-sourcing platform subject to a congestion charge. The platform determines the ride prices over the transportation network…
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…
Safety Challenges for Autonomous Vehicles in the Absence of Connectivity
Akhil Shetty, Mengqiao Yu, Alex Kurzhanskiy +3
Autonomous vehicles (AVs) are promoted as a technology that will create a future with effortless driving and virtually no traffic accidents. AV companies claim that, when fully dev…
Impact of Congestion Charge and Minimum Wage on TNCs: A Case Study for San Francisco
Sen Li, Kameshwar Poolla, Pravin Varaiya
This paper describes the impact on transportation network companies (TNCs) of the imposition of a congestion charge and a driver minimum wage. The impact is assessed using a market…
Large-Scale Traffic Signal Offset Optimization
Yi Ouyang, Richard Y. Zhang, Javad Lavaei +1
The offset optimization problem seeks to coordinate and synchronize the timing of traffic signals throughout a network in order to enhance traffic flow and reduce stops and delays.…
A Queuing Approach to Parking: Modeling, Verification, and Prediction
Hamidreza Tavafoghi, Kameshwar Poolla, Pravin Varaiya
We present a queuing model of parking dynamics and a model-based prediction method to provide real-time probabilistic forecasts of future parking occupancy. The queuing model has a…
Optimal Resource Procurement and the Price of Causality
Sen Li, Akhil Shetty, Kameshwar Poolla +1
This paper studies the problem of procuring diverse resources in a forward market to cover a set of uncertain demand signals . We consider two scenarios: (a) $\bf{…
Market Implementation of Multiple-Arrival Multiple-Deadline Differentiated Energy Services
Yanfang Mo, Wei Chen, Li Qiu +1
An increasing concern in power systems is how to elicit flexibilities in demand, which leads to nontraditional electricity products for accommodating loads of different flexibility…
Selling Demand Response Using Options
Deepan Muthirayan, Dileep Kalathil, Sen Li +2
Wholesale electricity markets in many jurisdictions use a two-settlement structure: a day-ahead market for bulk power transactions and a real-time market for fine-grain supply-dema…
Regulating TNCs: Should Uber and Lyft Set Their Own Rules?
Sen Li, Hamidreza Tavafoghi, Kameshwar Poolla +1
We evaluate the impact of three proposed regulations of transportation network companies (TNCs) like Uber, Lyft and Didi: (1) a minimum wage for drivers, (2) a cap on the number of…
Making intersections safer with I2V communication
Offer Grembek, Alex Kurzhanskiy, Aditya Medury +2
Intersections are hazardous places. Threats arise from interactions among pedestrians, bicycles and vehicles, more complicated vehicle trajectories in the absence of lane markings,…
Sharing Storage in a Smart Grid: A Coalitional Game Approach
Pratyush Chakraborty, Enrique Baeyens, Kameshwar Poolla +2
Sharing economy is a transformative socio-economic phenomenon built around the idea of sharing underused resources and services, e.g. transportation and housing, thereby reducing c…
Mechanism Design for Demand Response Programs
Deepan Muthirayan, Dileep Kalathil, Kameshwar Poolla +1
Demand Response (DR) programs serve to reduce the consumption of electricity at times when the supply is scarce and expensive. The utility informs the aggregator of an anticipated…
Estimating Phase Duration for SPaT Messages
Shahana Ibrahim, Dileep Kalathil, Rene O. Sanchez +1
A SPaT (Signal Phase and Timing) message describes for each lane the current phase at a signalized intersection together with an estimate of the residual time of that phase. Accura…
Analysis of Solar Energy Aggregation under Various Billing Mechanisms
Pratyush Chakraborty, Enrique Baeyens, Pramod P. Khargonekar +2
Ongoing reductions in the cost of solar photovoltaic (PV) systems are driving their increased installations by residential households. Various incentive programs such as feed-in ta…
Effect of Adaptive and Cooperative Adaptive Cruise Control on Throughput of Signalized Arterials
Armin Askari, Daniel Albarnaz Farias, Alex A. Kurzhanskiy +1
The paper evaluates the influence of the maximum vehicle acceleration and variable proportions of ACC/CACC vehicles on the throughput of an intersection. Two cases are studied: (1)…
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…
Measuring Impact of Adaptive and Cooperative Adaptive Cruise Control on Throughput of Signalized Intersections
Armin Askari, Daniel Albarnaz Farias, Alex A. Kurzhanskiy +1
