Microgrids can operate both in grid-connected and islanded modes. It is essential to protect microgrids against all types of faults in both of the operation modes. Conventional overcurrent protection schemes are not adequate for microgrids due to bidirectional flow of fault current and limited flow of fault current through semiconductor devices. In addition, the setting values of all the concer...

Power substations are intensively renovated toward using information and communication technologies such as object oriented modeling and Ethernet networks. In the last two decades, Substation automation systems used capabilities of network communication services adopted from sophisticated international standardizations such as IEC 61850. Distributed safety related functions take advantage of th...

 Abstract— With the increasing deployment of Distributed Energy Resources (DERs) in the distribution system, DERs presents many challenges for smooth and stable operation of the grid. For the effective management of DERs extensive communication between different components of DER and distribution system is required. In an effort to standardize the communication methods and modeling of logical ...

The standard IEC 61850 has been used in Brazil since 2008 to systematize the parameters of data communication regarding substation automation an open, interoperable framework. Most electrical projects, which apply 61850, take only GOOSE message and MMS through station bus. However, recommends a second bus, named process In 2022 application bus is limited pilot-project on utility learn about its...

Device-to-device (D2D) communication is a potential technology to improve capacity and energy efficiency of the current wireless communication systems. This work is focused on the application of D2D communication underlaying LTE network for distributed automation (DA) in the smart grid (SG) context. The communication aspects of SG and DA are introduced, and considering the strict reliability an...

Most critical infrastructure systems can be modeled as cyber-physical systems whose cyber components control the underlying physical components so as to optimize specified system objectives based on physical properties, physical constraints, and the current and estimated state of the system. Such systems usually require supports for security and performance guarantees: wrongly received or misse...

This paper presents the design of a new substation automation system architecture based on industrial automation technology, the development of an IEC 61850 compliant distance protection scheme and its test results. The proposed centralized structure means benefits for system integration since a higher degree of standardization can be achieved. Furthermore the approach guarantees manufacturerin...
