Integration of IEC 61850 into a Distributed Energy Resources system in a smart green building

A Distributed Energy Resources (DER) system, composed of distributed generation and storage units, has been proposed as a promising enhancement to the traditional power grids. One key challenge to implement a DER system, however, places on standardizing the communication network for seamless information exchange. As one approach, this paper focuses on integrating IEC 61850, which is an international unified standard for standardizing the communication network within a substation, into a DER system, using the UCLA SMERC building as test bed. To this end, we discuss a mathematical model of PV generation, present a representative demand profile, and develop a battery charging/discharging control algorithm. Moreover, we demonstrate a procedure to integrate IEC 61850 into the DER system step by step, with configuring the communication network and defining the data structure for the information exchange.
