Control and management of distribution system with integrated DERs via IEC 61850 based communication

Distributed Energy Resources (DERs) are being increasingly integrated in the distribution systems and resulting in complex power flow scenarios. In such cases, effective control, management and protection of distribution systems becomes highly challenging. Standardized and interoperable communication in distribution systems has the potential to deal with such challenges to achieve higher energy efficiency and reliability. Ed. 2 of IEC 61850 standards, for utility automation, standardizing the exchange of data among different substations, DERs, control centers, PMUs and PDCs. This paper demonstrates the modelling of information and services needed for control, management and protection of distribution systems with integrated DERs. This paper has used IP tunnels and/or mapping over IP layer for transferring IEC 61850 messages, such as sample values (SVs) and GOOSE (Generic Object Oriented Substation Event), over distribution system Wide Area Network (WAN). Finally performance of the proposed communication configurations for different applications is analyzed by calculating End-to-End (ETE) delay, throughput and jitter.
