Project duration was 2010 to 2011.
Our research problem is that design, scheduling, and regulation of vehicle supported microgrids are coupled despite their different time scales, requiring an integrated approach for successful V2MG2V (vehicle to microgrid to vehicle) implementation. This project has three major goals:
Modeling: Create a V2MG2V modeling framework that is modular and scalable, so that new components (e.g., electric vehicles, generators, renewable resources) can be easily added or removed to scale the system up or down. The framework allows use of different representations for a given device or system to scale up or down the fidelity of the model. Thus, if the focus is to study a particular component connected to the grid, the model of that particular component could be easily replaced with a higher fidelity representation. Models allow analysis at different time scales, for example, analyzing the sustainability of the micro-grid over several months vs. analyzing the behavior of the micro-grid under sudden changes in power supply. Tactical vs. strategic benefits can be thus properly explored.
Design: Analyze and determine optimal sizing and component selection of all micro-grid components, including PHEVs, renewable and non-renewable power sources, and energy storage devices. Analysis and optimization include the objectives of reducing fossil fuel use, greenhouse gas (GHG) emissions, and micro-grid sustainability over long time periods (e.g., islanding of up to six months). Design and local control decisions are coordinated with micro-grid system control strategies to provide an overall system optimal operation that maximizes performance with minimum capital and operating costs, balancing tactical and strategic requirements of both the base and the vehicle fleet.
Control: Develop stochastic dynamic models and design a new energy management algorithm for the micro-grid power system to integrate renewable power sources and PHEVs efficiently. The optimal control strategy includes both short time scale effects, such as the electrical dynamics and power quality during source interruptions, as well as long time scale strategies to minimize fossil fuel use and GHG emissions.
