Abstract
Increasing environmental awareness and the requirement for lower project costs is forcing transit system suppliers to think more innovatively and engineer more accurately to strengthen their competitive edge. Of late, clients more often desire a system that is optimized to minimize the energy consumed during operation; a requirement that is often imposed upon transit system suppliers through financially binding energy commitments.
Electric rail transit systems are large consumers of energy. In trains with regenerative braking capability, a fraction of the energy used to power a train is regenerated during braking. This regenerated energy, if recuperated and reused, can result in economic as well as technical merits. One of the ways that this could be achieved is with the implementation of Wayside Energy Storage System (WESS). In addition to reducing energy consumption, energy storage systems can be operated to regulate system voltage levels, provide backup power in the event of a utility power outage, and relieve demand on the utility during the costlier operating periods.
This dissertation presents a stacked-benefits analysis of regenerative energy and wayside energy storage for New York City Transit (NYCT), and examines how the electric utility and the transit system can collaborate to gain the best value of energy storage.
