Communication based Predictive Dynamic Stability Scheme in Microgrid with High Penetration of Distributed Energy Resources

This paper proposes IEC 61850 communication for predictive dynamic stability scheme (PDSS) in microgrids. The required phasor data for estimation of future angles is communicated through IEC 61850-90-5 Routable-Sampled Value (R-SV) messages. Similarly, the protection commands (i.e. Trip signals) issued by the microgrid central controller, running PDSS algorithm, are communicated as Routable-GOOSE (R-GOOSE) messages. Furthermore, this paper presents the real time laboratory implementations of proposed IEC 61850 communication using IEC 61850 emulator platform. This IEC 61850 emulation platform is required to analyze the applicability and feasibility proposed IEC 61850 communication before its real-life implementation. Finally, the performance evaluation of proposed IEC 61850 communication for realizing PDSS scheme in terms of end-to-end (ETE) delays is presented.
