Implementation and Performance Evaluation of IEC 61850 based Home Energy Management System

As the number of electric vehicles and PV panels per household increases, the need for a coordination between these active components becomes more imminent. Home energy management systems (HEMS) have been proposed to increase efficiency, renewable energy capture and reduce costs for the owners. However, renewable energy is intermittent and time-dependent. To increase the capture of this source, an integrated control with EVs is required to store excessive solar energy. Furthermore, coordination with the load profile enables storage for use at a later time, or selling the excess energy to the grid. This requires the use of a Home Energy Management System (HEMS) that can coordinate all these components with the grid. Operation of these controllers need to be validated before actual deployment. In this paper, a standardized communication modeling based on IEC 61850 is developed for a HEMS controller. Using commercial software, different terminals are set up as Intelligent Electronic Devices (IEDs) and the operation of HEMS is emulated with proper message exchanges. Such validation is crucial to project's success before on-site deployment.
