Abstract:

A grand challenge for power grid management lies in how to plan and operate with increasing penetration of distributed energy resources (DERs), such as electric vehicles (EV) and solar photovoltaics. In this talk, we show how to find the loadability point with a large amount of EVs when the system parameters are known. For such a loadability analysis, we convert the power system's Jacobian matrix into a linear form and employ the concept of Pareto Front for an optimization. When the system parameters are unknown, we show how the support vector machine can be used to reproduce the power flow equation. Such a representation is subsequently used to schedule capacitor bank for preventing voltage issue caused by electrical vehicles. Finally, as existing grid has limited EV numbers, the grid data cannot be directly used for testing tools above towards deep electric vehicle penetration. Therefore, we demonstrate an EV robot-based testbed for validating the first two ideas in this talk.
