  A new paradigm of electricity generation at the distribution level, with
renewable and alternative sources, is possible with microgrids. The main idea
is to have microgrids deployed on low- or medium-voltage active distribution
networks. They can be advantageous in many different ways, such as improving
the energy efficiency and reliability of the system and reducing transmission
losses and network congestion. There are challenges in implementing MGs with
DER units, those are related to power quality and stability issues voltage and
fault level changes, energy management, low inertia, further complex protection
schemes, load and generation forecasting, cyber-attacks, and cyber security.
This paper shows the deep utilization of advanced, accurate, and fast
methodologies such as artificial intelligence-based techniques. They guarantee
efficient, optimal, safe, and reliable operation of smart grids safe against
cyberattacks. AI refers to the computer-based system's ability to perform tasks
with intelligence typically associated with human decision-making, they can
learn from past experiences and solve problems.
