ABSTRACT
The smart grid is an electrical power grid that is integrated with an
AI-enabled, two-way communication network providing energy and
information. It is a technology that enables instantaneous feedback
from various sensors and devices on the operation of the power grid.
Although AI is relatively new, it is poised to revolutionize the way
we produce, transmit, and consume energy. AI will constitute the
brain of future smart grid. The power sector has started to use AI and
related technologies for communication between smart grids, smart
meters, and Internet of things devices. This paper presents some
applications of AI in smart grid.

INTRODUCTION
We all depend on energy to do things. Electricity
has been one of the most important and the most
widely used forms of energy since the 19th century.
The electric power has changed our society. The
electric industry essentially consists of three primary
functional areas: generation, transmission, and
distribution. This entire structure is popularly known
as the “grid.” Thus, the power grid is a dynamic
power system that delivers electric power from a
generation system through transmission and
distribution systems to end-users. The concept of
smart grid is shown in Figure 1 [1].
The power infrastructure consists of a vast network of
power plants, transmission lines, and distribution
centers (comprising roughly 5,800 power plants and
over 2.7 million miles of power lines). This
deteriorating structure supports one-way power flow
from centralized generation to end customers and is
yet to receive a modern overhaul [2]. The energy
sector worldwide faces some challenges related to
rising demand of increasing global population,
integration with various distributed components,
efficiency, changing supply and demand patterns.
These challenges are more acute in developing
nations.
The word “smart” in smart grid refers to the notion of
a power grid with intelligence. The main objective of
the smart grid is to bring reliability, flexibility,
efficiency, and robustness to the power system. Smart
grid does this by introducing two-way data
communications into the power grid. Thus, the smart
grid consists of the power infrastructure and
communication infrastructure, which correspond to
the flow of power and information respectively [3].
For efficiency, a smart grid infrastructure should also
include distributed generation and AI.
OVERVIEW ON ARTIFICIAL INTELLIGENCE
The term “artificial intelligence” (AI) was first used
at a Dartmouth College conference in 1956. AI is
now one of the most important global issues of the
21st century. AI is the branch of computer science
that deals with designing intelligent computer systems
that mimic human intelligence, e.g. visual perception,

speech recognition, decision-making, and language
translation. The ability of machines to process natural
language, to learn, to plan makes it possible for new
tasks to be performed by intelligent systems. The
main purpose of AI is to mimic the cognitive function
of human beings and perform activities that would
typically be performed by a human being. Without
being taught by humans, machines use their own
experience to solve a problem.
AI is stand-alone independent electronic entity that
functions much like human expert. Today, AI is
integrated into our daily lives in several forms, such
as personal assistants, automated mass transportation,
aviation, computer gaming, facial recognition at
passport control, voice recognition on virtual
assistants, driverless cars, companion robots, etc. AI
is not a single technology but a range of
computational models and algorithms.
Some forms of AI that are most commonly used in
electrical and computer engineering include the
following [4,5]:
Expert systems: They solve problems with an
inference engine that draws from a knowledge
base equipped with information about a
specialized domain, mainly in the form of if-then
rules. Expert systems are the earliest and most
extensive, the most active and most fruitful area.
Fuzzy logic: This makes it possible to create rules
for how machines respond to inputs that account
for a continuum of possible conditions, rather
than straightforward binary.
Neural networks: These are specific types of
machine learning systems that consist of artificial
synapses designed to imitate the structure and
function of brains. They are similar to the human
brain. They are made up of artificial neurons, take
in multiple inputs, and produce a single output.
The network observes and learns as the synapses
transmit data to one another, processing
information as it passes through multiple layers.
Machine learning: This includes a broad range
of algorithms and statistical models that make it
possible for systems to find patterns, draw
inferences, and learn to perform tasks without
specific instructions. Machine learning is a
process that involves the application of AI to
automatically perform a specific task without
explicitly programming it. ML techniques may
result in data insights that increase production
efficiency. Today, artificial intelligence is narrow
and mainly based on machine learning.
Deep learning: This is a form of machine
learning based on artificial neural networks. Deep
learning architectures are able to process
hierarchies of increasingly abstract features,
making them especially useful for purposes like
speech and image recognition and natural
language processing. Deep learning networks can
deal with complex non-linear problems.
Natural Language Processors: For AI to be
useful to us humans, it needs to be able to
communicate with us in our language. Computer
programs can translate or interpret language as it
is spoken by normal people.
Robots: These are computer-based programmable
machines that have physical manipulators and
sensors. Sensors can monitor temperature,
humidity, pressure, time, record data, and make
critical decisions in some cases. Robots have
moved from science fiction to your local hospital.
In jobs with repetitive and monotonous functions
they might even completely replace humans.
Robotics and autonomous systems are regarded as
the fourth industrial revolution.
These AI tools are illustrated in Figure 2 [6]. Each AI
tool has its own advantages. Using a combination of
these models, rather than a single model, is
recommended. AI systems are designed to make
decisions using real-time data. They have the ability
to learn and adapt as they make decisions.
AI IN SMART GRID
Like other industries, the power sector has been
inundated by AI-enabled technologies. To support the
existing systems and to extend the flexibility and
applicability of smart grids, AI has been naturally
adapted. As a result, large regional grids will be
replaced by microgrids that manage local energy
demand.
Researchers at Argonne National Laboratory (the first
US national laboratory) are developing new ways to
extract insights from the massive data on the electric
grid, with the intent of ensuring greater reliability,
resilience, and efficiency. They are working on
optimization models that use machine learning, to
simulate the electric system and the severity of various
problems [7].
Some of the adapted AI techniques in the smart grid
include [8]:
Managing the grid users and controllers
System based operation strategies for the grid
Power supply optimization
Consensus-based intelligent distribution
techniques
Machine learning and deep learning enabled
costing mechanisms

Intelligent energy storage systems
Intelligent voltage profile regulation techniques
using smart algorithms
Integrating privacy into the smart grid.
APPLICATIONS OF AI IN SMART GRID
Artificial Intelligence is everywhere. It is the fastest
growing branch of the high-tech industry. AI’s vast
potential has motivated several initiatives by utilities,
government agencies, and academia. The US
Department of Energy (DOE) recently established a
new Artificial Intelligence and Technology Office
(AITO) to coordinate the agency’s AI development,
delivery, and adoption [6]. In September 2017, the
DOE funded researchers at Stanford University to use
artificial intelligence to improve grid stability. The
UK’s National Grid collaborated with DeepMind to
add AI technology to the country’s electricity system.
The German government sees AI as a key strategy for
mastering some of our greatest challenges such as
climate change and pollution.
AI is becoming more and more important in the
energy industry. Typical areas of application are
autonomous grids, smart meters, energy consumption,
electricity trading, failure management, and energy
storage. These applications are discussed as follows
[9-11].
Autonomous Grid: In the US, the DOE is
developing an autonomous grid using AI. With
the power grids now collecting energy from
different sources and the increasing
decentralization of the grids, operating the grids
has become more complex. This requires
analyzing massive data. Artificial Intelligence
helps process this data as quickly and efficiently
as possible, thereby bringing stability and
efficiency.
Smart Meters: A smart meter is a high-tech
meter that measures electricity consumption and
provides additional information to the utility
company unlike the conventional, analog meter.
Smart meters (SMs) are essentially digital meters
that read remotely over a secure wireless network.
They are an important component of the smart
grid system. They will be able to constantly
monitor demand and supply of customers. These
smart meters process information that can be
related to a person and be privacy sensitive. With
smart metering, one can monitor every appliance,
providing the homeowner with a comprehensive
picture of their energy usage [12].
Energy Consumption: In addition to making the
power grid smart, flexible, and autonomous, AI
algorithms help utilities and energy companies
understand and optimize user’s behavior and
manage energy consumption. In a smart
networked home, the networked devices react to
prices on the electricity market and adapt to
household usage accordingly. By monitoring the
energy consumption pattern of individuals and
businesses, AI companies can offer solutions to
optimize usage, save electricity, and reduce costs.
For example, SmartTthermostat Nest adapts
temperatures according to user behavior to reduce
energy consumption.
Electricity Trading: In electricity trading, AI
helps improve forecasts. Machine Learning and
Neural Networks play an important role in
improving forecasts in the energy industry.
Failure management: Without regular checks on
power equipment, equipment failures are
common. Using AI to observe equipment and
detect failures before they happen can save
money, time, and lives.
Energy Storage: The Smart grid with energy
storage will continuously collect massive data to
make timely decisions on how best to allocate
energy resources. Combined with other
technologies such as big data, the cloud and the
Internet of things (IoT), energy storage with AI
can play an important role in power grid
management. A smart grid with energy storage is
able to use energy sources in the most efficient
way by better integrating renewable resources.
These applications are simply a taste of what is
ultimately possible. There are many more
applications of AI in smart grid or energy industry
such as energy management, managing electric
vehicles, network planning, fraud detection, load
forecasting, stability analysis, security assessment,
stability assessment, fault diagnosis, fault prediction,
and stability control in smart grids. Figure 3 shows
some of the applications of AI in energy industry
[10].
BENEFITS
The application of AI-based technologies to the
power grid cuts energy waste, facilitates the use of
clean and renewable energy sources, and improve the
planning, operation, and control of the power
systems. The technologies can also help improve
power management, efficiency, stability. resilience.
and transparency, and increase the use of renewable
energy sources. Smart grid facilitates large amounts
of renewable energy integration.
A major benefit of AI is the ability for the customers
and the grid to be connected directly, creating win-
win situation. The price of solar has come down

recently years to bolster the cost-effectiveness of
renewables. This can lead to a more efficient market
and more cost-effective electricity production. It is
realistic to expect the smart grid system to lower
electricity bills and prevent catastrophic blackouts. AI
can help use less energy to accomplish more. It is
also helping compress and analyze the massive
amounts of data produced by energy industry. To
curb data access by private companies, the European
Union (EU) Commission has developed four basic
ethical principles for AIs: AI should respect human
autonomy, avoid social harm, be fair, and be
explainable.
CHALLENGES
Smart grid faces a wide range of challenges, such as
extreme weather, imperfections in the available
infrastructure, reliability issues, equipment failures,
gigantic customer base, decentralized generation, and
decarbonizing the global economy. A major challenge
is the rise of distributed generation, where individual
customers generate and use their own electricity from
renewable sources, such as wind and solar. The
current power system was not designed to
accommodate this diversification in energy sources
and fluctuating supplies of renewable energy. Industry
leaders in the AI energy grid industry are aware of
these challenges and must address them. The use of
AI in smart grid is not without risks. One risk has to
do with the privacy of customer data collected by AI
systems.
THE FUTURE OF AI IN SMART GRID
Artificial intelligence holds significant potential
across a wide array of sectors. It is expanding its
scope over tasks traditionally performed by humans.
Its applications in the energy industry are helping to
make the grid “smarter” or more responsive, thereby
develop the smart grid of the future. AI has been
regarded as the brain behind the future smart grid,
enabling the real-time optimization and automation of
distribution planning and operation decision. The
smart grid is a dynamic system that continues to
evolve as technologies are tested and perfected [13].
Although the use of AI in the smart grid faces some
challenges such as insufficient reliability, imperfect
infrastructure, and lack of special algorithm for power
industry, AI is a powerful tool to push smart grid into
the new generation of power systems. AI supports
and optimizes electric networks around the world,
pushing the concept closer towards a global adoption.
It should be added to all levels in the energy grids, in
order to enhance their development.
Although the smart is not quite here yet, it is slowly
becoming a reality. It is on its way to usher the energy
industry into a new era of reliability, availability, and
efficiency. Significant investments in the
infrastructure will be needed to help smart grids fully
take off [14].
New generation of energy networks will make
efficient use of renewable energy sources, support
real time and efficient demand response, as well as
the large-scale deployment of electric vehicles (EVs)
[15]. To provide a low-cost and flexible solution for
the grid-wide information exchange, wireless
communications technology is expected to play the
key role in the emerging smart grid applications.
CONCLUSION
The smart grid is the developmental trend of power
systems. It has attracted much attention all over the
world. It provides a platform for clean, sustainable,
efficient and reliable energy generation, delivery, and
consumption. It is inevitable that the smart grid will
become part of our society. The global energy
demand is expected to increase steadily in the future.
Therefore, future generations should realize that AI
and energy are not mutually exclusive career paths.
For more information about artificial intelligence in
agriculture, one should consult the books in [16,17].
