1) The document summarizes a presentation on co-simulating plug-in electric vehicle (PEV) coordination schemes over a fiber-wireless (FiWi) smart grid communications infrastructure. 2) Simulation results showed that uncoordinated PEV charging can cause critical voltage fluctuations as penetration levels increase, while coordinated schemes using a proactive algorithm distributed the load better. 3) A reactive control algorithm was also proposed to quickly unplug PEVs and solve critical voltage fluctuations detected by sensors communicating with a distribution management system over the FiWi network.
