Extreme climatic conditions pose significant operational challenges to power systems by increasing fault occurrences, communication failures, voltage instability, and large-scale outages. This study proposes a high resilience integrated emergency interconnection and communication framework for reliable power system operation during extreme weather events. The proposed system combines Optimal Power Flow (OPF) control with hybrid communication technologies, including satellite, unmanned aerial vehicle (UAV), and Mobile Ad Hoc Network(MANET)-based communication systems. In addition, a hybrid artificial intelligence fault detection model integrating Random Forest (RF) and Support Vector Machine (SVM) with ensemble learning is developed for accurate fault identification. The methodology is implemented on the IEEE 14-Bus System using the Newton–Raphson load flow method. Extreme climatic conditions are modeled through scenario based simulations, while Monte Carlo simulations are employed to generate synthetic disturbances and faults. Communication performance is evaluated through delay and packet loss analysis within hybrid fiber–IoT communication networks. The framework also incorporates rule-based communication selection, optimization driven coordination strategies, load shedding optimization, and power balancing mechanisms to maintain system stability during emergencies. Experimental results demonstrate strong resilience and communication performance, achieving a Voltage Deviation Index (VDI) of 0.04281 p.u., Resilience Index (RI) of 0.7241, Recovery
Time (RT) of 5.64 hours, and Energy Not Supplied (ENS) of 2.85 MWh. The communication system records latency between 0.005 s and 0.018 s, throughput of 99.34 Mbps, and a Communication Reliability Index (CRI) of 0.9782. The hybrid fault detection model achieves 98.83% accuracy, confirming the effectiveness of the proposed framework for resilient smart grid operations.
