The increasing reliance on smart grid infrastructures, particularly for critical services such as hospitals, necessitates highly secure, efficient, and resilient energy management systems. In response to the vulnerabilities exposed during the COVID-19 pandemic, particularly in Gujarat where power failures disrupted ventilator operations, this paper introduces CryptoGrid, a novel hybrid cryptographic ledger framework for smart grid cyber security and energy redistribution. It is proposed to achieve grid security against advanced cyber threats using the proposed architecture that incorporates blockchain-powered identity authentication, federated learning, and GAN-based anomaly detection. The agent-based control systems and optimization of energy management with Multi-Agent Reinforcement Learning (MARL) framework with PSO-GA hybrid credit pricing and redistribution have been used to improve energy management. Priority nodes are critical infrastructures like hospitals and are provided in case of an outage automatically by mobile EV energy banks and the decentralized microgrid systems. The experimental findings indicate that CryptoGrid is efficient in providing secure and life-saving energy solutions with an anomaly detection accuracy of 98.7, a 72% drop in the energy wastage, and a 29% increase in emergency energy supply.
