Abstract

The IEC61850 Standard has constantly evolved since it was first published in 2002. It has been extended to cover more aspects of power grid operations. On top of its initial focus on substation automation system, the standard family has been extended to cover hydropower plants, electric vehicle (EV) charging systems, distributed energy resources (DER), synchrophasor, and control centres. It is foreseeable that IEC61850 Standard will govern the way information is being handled and transmitted in future innovative grid applications.

This thesis first presents a co-simulation framework for IEC61850-based smart grids simulation. The co-simulation framework was built according to IEEE 1516 HLA Standard, which enforces causality constraints and guarantees the simulation results to be deterministic and repeatable.

In addition, an IEC61850 Model for Centralized Microgrid Protection Scheme is also presented in this thesis. It enables the Centralized Microgrid Protection Scheme can be deployed in IEC61850 based Microgrid. The proposed model is then verified with the co-simulation platform.

Furthermore, this thesis also presents the design of MMS Report Gateway Model. By using the model, redundant retransmissions caused by R-GOOSE can be eliminated, which in turn conserves WAN bandwidth during grid recovery. The proposed model is implemented by placing a MMS Gateway at each substation to translate GOOSE Messages to MMS Reports. The model has been tested with the co-simulation platform using the distance protection scenario. Simulation results have verified the proposed model in terms of communication latency performance with different links speed and utilization rates of WAN.

It is believed that both the proposed framework and models will benefit the implementation of the IEC61850 Standard in current smart grid applications.
