Since renewable energies have been and will be massively integrated, electrical power grids require more refined generation dispatch modes and smarter communication methods. In this paper, the real-time generation dispatch and communication architecture of smart grid with renewable energy are studied. Firstly, the technical characteristics and application background of smart grid communication ...

The dynamic operation of power transmission systems requires the acquisition reliable and accurate measurement state information. use TCP/IP-based communication protocols such as IEEE C37.118 or IEC 61850 introduces different gateways to launch cyber-attacks compromise major system functionalities. Within this study, a combined network intrusion phasor data anomaly detection is proposed enable ...

Abstract The digitalization of substations leads to a high degree automation, which is referred as Digital Substations with the use IEC 61850. An increase in cybersecurity necessary, and technically enabled by detection incident response systems – security-by-design currently often secondary. next transformation step introduced outlined this paper cyber-resilient digital substation. Based on st...

During the last years utilities have been facing a strong trend towards new technologies and standards. The most significant task is to fundamentally transform the capabilities and bring new solutions that support better power quality supply. Standardization solution IEC 61850 in terms of protection, monitoring and control functions is a promising solution that provides a great impact on substa...

With preliminary applying of Electronic Transformer (ET) based on IEC 61850 standards in power grid, the calibrations of tested transformers have attracted extensive research attention. This study proposes a novel Calibration System of ET (CSET) based on high-accuracy card. Data acquisition of ET and Standard Trans-former (ST) is gotten by optic Ethernet and PCI-4462 data acquisition card, resp...

Digital substations are mostly important in the future of the electric power industry which makes their testing a critical process to ensure the required reliability and security of the grid. The paper introduces the definition of a digital substation and efficient testing, as well as the requirements for isolation during testing. It later describes testing related features in IEC 61850 Edition...

The trend of transforming substations into smart automated facilities has led to their swift digitalization and automation. To facilitate data exchange among equipment within these substations, the IEC 61850 standard become predominant standard. However, this standardization inadvertently made more susceptible cyberattacks, which is a significant concern given confidential information that tran...

The IEC 61850 standard aims at digitization substations and provides interoperability between various Intelligent Electronic Device vendors. process is accompanied by several challenges related to data transmission on the ethernet network protection behavior under these conditions. Among challenges, we can mention packet loss, delay, duplicate frame, which occurs when merging units (publisher) ...
