Smart grid automation using IEC 61850 and CIM standards

An overview of basic IEC standards for smart grid applications is given and some examples of feasible information and communication technology for smart energy systems are shown. As ICT key standards for power grid automation, the two core standards IEC 61850 and IEC 61970 are presented in the paper. Protection automation relying on smart grid ICT technology is shown, and the hurdles to be overcome for the realization of smart grid automation are discussed. Practical examples for are demonstrated. One approach of making different standards work together is presented, which today is still not sufficiently solved and is a main hurdle on the way towards a seamless smart grid automation system.
