Energy resiliency involves the next generation of the electrical grid (smart grid), with a purpose to allow integration of conventional, renewable, distributed power generation, energy storage and distributed storage, transmission and distribution, intelligent approaches for smart grid, management by computational intelligence technologies for sustainable energy, machine learning, IoT, big data applications and demand management.

Renewable energy is essential in transitioning to a less carbon-intensive economy and a more sustainable energy system. The high penetration and uncertain power outputs of renewable energy creates a great challenge to the stable operation of energy systems. The spread of the smart grid is extensive and also crucial around the world. It involves and deals with multidisciplinary fields such as energy sources, control systems, cyber and physical security, communications, computation, generation, transmission, distribution, customer, operations, markets, and service provider.

Energy resilience is enhanced with the help of technological advances through better risk reduction, response, mitigation, rehabilitation, and reconstruction.

A broad variety of technologies are manipulated, emphasizing specifically on new technologies such as cyber physical systems, geotechnology, drone, and virtual reality (VR) / augmented reality (AR). Other groups of emerging advanced technologies including a decision support system and an early warning system are also addressed. These technologies help resiliency of energy supply and consumption.

Energy systems are made more efficient and secure against traditional threats such as extreme weather events and technical failures by Increasing digital capabilities. At the same time, the energy sector is exposed to cyberattacks through an increasing attack surface by digitalization. While cyberattacks remain responsible only for a small fraction of energy supply disruptions, the potential damage is significant and increases quickly.

Cryptographic helps all aspects of the energy system (availability, integrity, and confidentiality). Variety types of cryptography are available differing in their symmetry of decryption key and transfer time.

Commonly, energy consumers have been very passive actors in energy systems. However, the status is changing with the increasing number of consumers connected to smart grids, accelerating amount of data flows, and control abilities.
