Multi-Infrastructure Modeling of Smart and Connected Communities
This case study evaluates interdependent energy, transportation, and communication infrastructure for the design and operation of future smart and connected communities. To assess interdependencies, three case studies of gradually increasing complexity are included (energy, energy + transportation, energy + transportation + communication). The test community consists of three blocks (two residential, one commercial) with mixed building types; renewable generation (solar PV, wind); power grid connection; IEEE 16 node distribution feeder; electric vehicles; wireless communication network; and interconnecting roads, power lines, and transmission lines.
Quantitative analyses show that the deviation of the average velocity on the road can be 10.5% and the deviation of the power draw from the grid can be 7% with or without considering the transportation and communication system at the peak commute time, indicating the presence of notable interdependencies.
