Emergence of the Energy Internet (EI) demands restructuring of traditional electricity grids to integrate heterogeneous energy sources, distribution network management with grid intelligence and big data management. This paradigm shift is considered to be a breakthrough in the energy industry towards facilitating autonomous and decentralized grid operations while maximizing the utilization of Distributed Generation (DG). Blockchain has been identified as a disruptive technology enabler for the realization of EI to facilitate reliable, self-operated energy delivery. In this paper, we highlight six key directions towards utilizing blockchain capabilities to realize the envisaged EI. We elaborate the challenges in each direction and highlight the role of blockchain in addressing them. Furthermore, we summarize the future research directive in achieving fully autonomous and decentralized electricity distribution networks, which will be known as Energy Internet.

Protection schemes are mandatory for the safety and reliability of power systems operations. A Power System Simulator has been built as a teaching tool in order to provide a clear picture of the system, including generation, transmission and distribution, for the Electrical Engineering undergraduate. The simulator is based on using real 11kV vacuum circuit breakers as the base of operations and is a voltage scaled down version of a power system. The implementation of a distribution system at 400V and the improvements to the controllability of the motor generator set which models generation in one area of the simulator are discussed. A PSCAD (Power System Computer Aided Design) simulation is presented to validate the physical model built. The Implementation and co-ordination of protection schemes for an interconnected network is a challenging task. Thus the paper discusses the implementation of a bus bar protection scheme and the integration of protection aspects with the overall system.
