  • Enhancing Substation Protection Against Cyber Attacks Using LSTM Autoencoder
    Ravi Prakash Mahobia, Baidyanath Bag, Swapnajit Pattnaik
    2025 IEEE 4th International Conference on Smart Technologies for Power Energy and Control Stpec 2025 Conference Report, 2025
    Digital technology has significantly improved the robustness and operational efficiency of the smart grid. The integration of information and communication technology (ICT) in substations has enabled real-time monitoring and control of electrical infrastructures to be more feasible, with bidirectional data and power flow. However, this feasibility has increased the vulnerability of the critical assets of the smart grid. Line current differential relays (LCDRs) are among these vital assets, widely used for transmission line protection and increasingly vulnerable to malicious cyber activities. To manage this growing concern, the present study proposes a hybrid detection framework based on a Long Short-Term Memory Autoencoder (LSTM-AE) for cyberattack detection. The suggested approach utilises both temporal and spatial patterns present in the three phase current signals measured at the sending and receiving ends of the transmission line to identify anomalies indicative of cyber threats. Notably, this framework is designed to detect False Data Injection Attacks (FDIAs) with higher accuracy and recall compared to existing methods, while utilizing a more compact feature space. Furthermore, the reduced computational load of the proposed method makes it a practical solution for real-time protection in smart grid applications.
  • Comparative Analysis of Reconstruction-Based Loss Metrics for Attack Detection in LCDR-Based Transmission Line Protection
    Ravi Prakash Mahobia, Baidyanath Bag, Swapnajit Pattnaik
    2025 IEEE 4th International Conference on Smart Technologies for Power Energy and Control Stpec 2025 Conference Report, 2025
    The efficacy and reliability of the electrical grid have significantly improved with advancements in digital technology. The incorporation of Information and Communication Technology (ICT) into modern substations permits monitoring and control of the power grid in real-time. However, this interconnectedness increases the vulnerability of critical infrastructure to cyberattacks. Line Current Differential Relays (LCDRs), commonly used for transmission line protection, are potential targets for cybercriminals aiming to disrupt system functionality. This study proposes a Convolutional Autoencoder (CAE) architecture for accurately reconstructing normal data patterns and identifying anomalies indicative of malicious attacks. The model's performance is determined by two error metrics: Mean Absolute Error (MAE) and Mean Squared Error (MSE). A comparative assessment of metrics provides insights into the model's robustness and accuracy in detecting subtle deviations caused by False Data Injection Attacks (FDIAs), leveraging the temporal and spatial dependencies in three-phase current measurements at both local and remote ends to identify attacks on LCDRs. Experimental results demonstrate the model's capability to achieve high detection accuracy, highlighting its potential to enhance grid resilience against cyberattacks. The suggested model reduces computational complexity while effectively improving anomaly detection performance.
  • Protecting Substation Differential Relays Against Cyber Attacks Using Convolutional Autoencoder
    Ravi Prakash Mahobia, Baidyanath Bag, Swapnajit Pattnaik, Jagendra Kumar Narang
    2025 4th International Conference on Power Control and Computing Technologies Icpc2t 2025, 2025
    The development of digital technology has led to the advancement of electrical power systems and enhanced their reliability and efficiency. With this, the information and communication technology integrated substation devices have made it possible to monitor and control the modern power system smartly. However, all of this comes at the expense of the cyber vulnerability of the power system. The line current differential relays (LCDR) are the most commonly used relays for the protection of transmission lines. LCDR safeguards the lines from faults and could be misused maliciously by the cyber attackers to mal-operate the system. To resolve this issue, this paper introduces a cyber-threat detection system grounded on an unsupervised deep convolutional autoencoder (DCAE) framework, which detects malicious attacks on LCDRs. Remote and local end three-phase current measurements of the protected line with various fault characteristics have been considered to process this. The proposed framework uses fewer features against the existing attack detection methods for LCDRs. The three different scenarios of false data injection attacks (FDIA) have been analyzed at work, and the result shows that the framework achieves higher precision and recall rates with fewer learnt features.

    The power stabilization in photovoltaic systems is well studied. There exist number of approaches in stabilizing the output power of PV systems. The most approaches concern about the input power and residual energy of capacitors. Still they suffer to achieve higher performance in power stabilization. To handle this issue, an efficient Fuzzy inference based Power stabilization model (FIPSM) is presented in this paper.

At each duty cycle, the method reads the input voltage and identifies set of circuits were in sleep or charging mode. With the list of circuits, the method computes the Fuzzy Inference Voltage Stabilization Support (FIVSS) for various circuits. Based on the value of FIVSS, the method identifies a unique or a subset of circuits to support stabilization. The proposed model improves the performance of power stabilization in photovoltaic systems.
