IEC 61850 based smart grid security
This paper discusses mainly the requirements of enhanced IEC 61850 security parameters for smart grid. Since IEC 61850 has been specified in 2003, smart grid was developed rapidly. This modern grid requires reliable, flexible, efficient and secured communication standards. Recent researches confirm that IEC 61850 meets the first three requirements, yet

Ground Fault Location and Severity Estimation Method for DC/DC Converters
A method for detection, location and severity estimation of ground faults for DC/DC converters has been designed. The method consists in analysing the voltage signal of a grounding resistor that connects the neutral point of the system—which can be the AC neutral point of the star of the main power transformer or an artificial DC midpoint—and ground ...

Attack Resilient Microgrid: Impact Characterisation, Online Anomaly Detection and Mitigation
This paper proposes an attack‐resilient control framework for grid‐connected microgrids that enable real‐time detection and mitigation of stealthy cyber‐physical attacks on control and measurement signals. Using an online LSTM‐based anomaly detection system and a model‐based mitigation strategy, the framework maintains near‐optimal performance even ...
