Project Summary

This project builds upon the solar PV, PV thermal and energy storage demonstrations that are a portion of the UC Davis (UCD) research project funded under the Solicitation #2 grant. The proposed project will develop and demonstrate an optimal control strategy for demand response using a smart grid-tied energy storage system powered by PV and supported with second-life Lithium ion batteries. The UCD team will evaluate the control schemes in a residential home equipped with PV panels, smart appliances and a level 2 charging system for a plug-in hybrid electric vehicle. Three sets of management strategies (modes) will be examined to minimize peak demand as well as to lower electricity costs. The UCD team will also perform cost and lifetime assessments of the system to examine the feasibility of using second life traction batteries as grid tied energy storage. This project will examine the concepts of optimized solar energy use in a residential home, transportation and communication between vehicles and the electricity grid, and second-life applications for traction batteries.
