A Sustainable, Portable, and Efficient Electricity Delivery (SPEED) System

In this paper, a sustainable, portable, and efficient electricity delivery (SPEED) system is designed and built for community emergency/disaster relief with sustainable power solutions. The system consists of a 180W PV array with six serial-connected solar panels, a 1.8kWh battery system, a SYNDEM power converter, and a human-machine interface. Advanced power electronics control technologies are designed and implemented to guarantee the autonomous operation of the SPEED system at either islanded mode or grid-tied mode to cope with emergency/disaster relief scenarios. Field testing is conducted to validate the effectiveness and efficiency of the SPEED system.
