Abstract

Power companies are developing plug-in electric vehicle (EV) smart charging programs to shift charging to off-peak hours, when demand is lower, and to align charging with renewable energy. An internet-based survey of over 1,000 Americans ascertains opinions on supplier-managed charging (SMC) programs and the expected benefits of program participation. About 25.6% of Americans say they would never accept SMC, but 8.8% would be willing to use an app or timer to stagger charging themselves. Up to 36.9% would cede some control to their supplier (17.6% at night only, 10.3% on grid-strained days only, and 8.9% every day to optimize the local grid). Multinomial logit models indicate that Americans with household EVs and wholesale-indexed energy rates are more willing to accept an SMC program. Tobit model results indicate the minimum required bill credits of $126 (one-time only) and $17 (per year) for SMC program participation.

When Are We Willing to Wait? Prescriptive Challenges in Evaluating Intertemporal Outcomes

Abstract

The classic normative model for intertemporal preferences uses a constant discount rate, but behavioral experiments have shown that people do not tend to make choices consistent with a constant discount rate. We first present normative models for time preferences, then discuss descriptive results for choices between single outcomes occurring at different times. People often have different implicit discount rates for different types of scenarios, and several anomalies arise consistently. We contrast those results with findings for preferences for sequences of multiple outcomes over time. People tend to prefer increasing or constant sequences of outcomes over time, especially when the outcomes are non-monetary in nature. This suggests a willingness to wait for improvement, but not in the way that classical discounting would prescribe. We end with prescriptive nudges to improve dynamic consistency and pose questions still to be resolved about how decisions involving outcomes over time can be improved prescriptively.

Market structure and quality determination for complementary products: Alliances and service quality in the airline industry

International Journal of Industrial Organization

Abstract

This paper explores the effect of market structure on quality determination for complementary products. The focus is on the airline industry and the effect of airline alliances on flight frequency, an important element of service quality. With zero layover cost, the choice of flight frequencies has the same double-marginalization structure as in the usual alliance model, leading to a higher frequency in the alliance case as double marginalization is eliminated, along with a lower full trip price and higher traffic. The surprising result of the paper emerges with high-cost layover time, where double marginalization in frequencies is absent and where an alliance reduces service quality via a lower frequency, with the full price potentially rising (in which case traffic falls).

A solid oxide fuel cell-gas turbine hybrid system for a freight rail application

ASME 2019 13th international conference on energy sustainability

Abstract

The simulation of a Solid Oxide Fuel Cell-Gas Turbine (SOFC-GT) hybrid system for a locomotive application is presented. Using Matlab Simulink, a 2.8 MW SOFC system was combined with a 500 kW GT and simulated to travel the route from Bakersfield to Mojave in California. Elevation data was imported using the Google API Console and smoothed in order to calculate the dynamic power demand for the SOFC-GT system, assuming 480 tons of freight per 120 ton locomotive traveling at an average speed of 45 mph. The SOFC-GT system model follows this demand without causing a significant disruption to the speed of the locomotive. A lithium-ion battery was included into the system model to improve the net system efficiency and make the operation smooth enough for the highly dynamic route. The overall efficiency along the simulated route has been calculated as 57% operating on partially pre-reformed natural gas fuel. These results suggest the development of a physical prototype of the simulated system and are very promising for the future of freight rail transportation throughout the US. CO2 and particulate matter emissions are significantly reduced compared to current diesel-electric locomotives and it is also possible to operate the system on hydrogen, i.e., completely emission-free. A techno-economic analysis to assess the economic feasibility of this system is currently being prepared.
