Application of Digital Technologies for Expansion Planning of Integrated Energy SystemsBackground and benefits of energyDigital Energy3 Background and benefits of energy
digitalization
First of all, it is necessary to define the concept of
"digital energy". This concept is revealed in the Decree
of the President of the Russian Federation “On the
national goals and strategic objectives of the
development of the Russian Federation until 2024” No.
204 dated May 7, 2018. This document sets the goal: “...
to transform the priority sectors of the economy and
social sphere, including ... energy infrastructure through
the adoption of digital technologies and platform
solutions ... " by " ... implementing intelligent control
systems for electric power grid based on digital
technologies". It is worthwhile to add here that the said
applies not only to the electric power system, but also to
energy systems in general. These are first of all
heat/cool, gas and oil supply systems.
Thus, the digitalization of infrastructural energy systems
means a transition to a digital base of technical tools for
measuring,
collecting,
transmitting,
processing,
presenting information, as well as transferring and
implementing control actions, and using intelligent
information technologies at all stages from measuring
state variables of energy facilities and systems to
implementation of control actions. The need for
digitalization of infrastructural energy systems is
determined by significantly increasing consumer
requirements for the reliability of energy supply and the
quality of energy resources, due to the digitalization and
computerization of consumer production technologies.
The operation control of infrastructural energy systems,
which are transformed as a result of innovative
development, is fundamentally impossible without
effective control systems. These systems are
implemented
using
advanced
information
and
communication technologies and intelligent tools on a
digital basis. The physical and control subsystems of
energy systems are comparable in complexity and
responsibility. Energy systems are becoming complex
cyber-physical systems. Objective tendencies of changes
in the structure and properties of future energy systems
complicate the conditions for their controllability, which
is shown in [16] by the example of electric power
systems.
The digitalization of infrastructure energy systems is
actively developing. There are numerous examples of the
successful implementation of intelligent digital
technologies in electric, heat and gas supply systems.
The advantages of energy digitalization are determined
by the following statements:
significant improvement in the reliability of energy
supply and the energy quality and energy services,
a radical change in the paradigm of relationships
between stakeholders in the field of energy supply based
on the principles of the Internet of energy,
implementation of large-scale economic effects for
all stakeholders,
increasing the efficiency of decisions and the work of
company personnel.
