About the Tutorial

The first part of the course concentrates on the definition of the Smart Grid and its components. It highlights the requirements for reliability, security and efficiency. It later concentrates on the requirements for integration of the different renewable distributed energy resources and their impact on protection, automation and control systems.

The second part of the course covers the main characteristics of the IEC 61850 standard and then concentrates on the evolution from Edition1 to Edition 2. The changes in the data models, the model hierarchy, the communication services and the System Configuration Language. The changes in the standard that are driven by the needs of different Smart Grid related applications are also presented.

The third part of the course covers the digital substations as a key component of the Smart Grid. It discusses the benefits of digital substations and gives practical examples of its different applications for the Protection, Automation, and Control (PAC) and how they reduce the fault clearing times in order to support the ride-through requirements for the DERs.

The last part of the course covers the testing aspects of digital substations and distributed wide area protection, monitoring and control applications. It starts with the description of the Quality Assurance Process defined in IEC 61850 Part 4 - from the early IED design phase through acceptance, commissioning and subsequent supervision and maintenance of the PAC system. Later the testing related features of IEC 61850 are described, followed by examples of testing of substation, substation-to-substation and wide-area protection applications.
