Shared Electric Vehicle Systems Based on IEC 61850-90-8: Implementation Proposal and Proof of Concept

Urban mobility is a central theme in dis-cussions about city development and quality of life. It refers to the ease and efficiency people move within the urban environment. However, with population growth and increased use of individual transport, we can ob-serve several problems, such as traffic congestion, air and soil pollution, and the emission of greenhouse gases. In this sense, this article proposes a sustainable and shared electric vehicle system based on IEC 61850 standard. The proposal addresses the data modeling of the system components, the communication protocols used, and the functional architecture of the system. We base the SCADA system developed for the solution, the electric vehicles, the charging stations, and all the control, monitoring, and supervision devices involved on IEC 61850, where we use its data modeling to guarantee the interoperability attribute. The proposed charging station charges vehicle batteries from solar panels installed at the station, reinforcing the system's sustainability. We present an implementation proposal with a proof of concept case study through a testbed with SEL 451–2 and SEL 421–3 IEDs, an Omicron CMC 356 test case, a GE Reason S20 switch, and an Elipse E3 software. The results show the proposal is feasible, and the IEC 61850 Standard can achieve our shared electric and sustainable vehicle system needs whit good monitoring, supervision, and control performances.
