Abstract
Grid electricity systems have evolved from un-complex systems and loosely coupled transmission grids, up to the state of the art present-day as highly complex and tightly coupled infrastructures, greatly based on automation systems with various levels of reliability. Tasmania's electricity ecosystem is both representative of international norms and sharply more mature in terms of renewable energy penetration. The management of the Tasmania's electricity infrastructure has become dependent on its information system infrastructure as automation continues to replace manual operations, and as market forces demand more accurate and suitable information as the power system equipment become older. Adapting Tasmania's electricity grid with Community Resilience Microgrids based on wind power, residential solar PV and stored energy systems requires more complex monitoring and control of the electricity network. The Energy Cloud concept [1] sits at the confluence of relevant technology trends enabling two-way flow of electrons, shared infrastructure with many users connected to multiple networks, blending of centralized and decentralized control and management, and maximum flexibility. The latest White Paper on Security Standards in IEC TC57 progresses two infrastructures - the power system infrastructure and the information system infrastructure - concurrently while supporting coherence with cyber security requirements for business processes involving Home Area Networks.
