    Cooperative Approaches in Electrification of Public Transit Bus Systems (Mertcan Yetkin)

    Electrification of transit systems, within the scope of smart cities, plays a crucial role in the reduction of greenhouse gas emissions. From the perspective of a social planner, we study electric buses in an urban area coupled with power system operations. On the operational level, we co-optimize the smart grid and the transit fleet operation to provide ancillary services to the power grid during off-schedule times. We introduce two stochastic multi-period optimal power flow (OPF) problem formulations each providing a different set of recourse actions to manage the variable renewable energy uncertainty: ramping up/down of the conventional generators, or charging/discharging of the transit fleet. On the planning side, extending the deterministic formulation, we analyze various investment decisions by the transit party and the interactions with the existing power grid operations. We introduce several regulations for the transit party and analyze their effects on the cooperation. Given the recent momentum towards building smarter cities and electrifying transit systems, our results provide policy directions towards a sustainable future. Our study is motivated by a project with a large transit authority in California.

    Environmental Pricing Designs (Alberto J. Lamadrid)

    We study the problem of deriving financially adequate prices for trading a perishable commodity under a centralized auction with environmental considerations. Our model is based on an electricity market, with producers using conventional technologies with byproduct emissions; and environmentally clean producers subject to exogenous weather realizations, but lower emissions in production. For this purpose, we derive a new financially adequate market clearing pricing scheme. Unlike related financially adequate pricing schemes that only take into account the marginal market costs associated with market clearing commodity demands, the proposed pricing scheme also takes into account the marginal market costs associated with the market participants operating at maximum capabilities. The proposed pricing scheme allows to analyze the effects of environmental limitations in the market, as it internalizes, in the pricing signals, the costs or benefits associated with compliance of these limits by the market participants; and in particular, conventional technology producers including transit operators.
