The document proposes a conceptual model for a Cyber Physical Energy System (CPES) to improve energy efficiency. A CPES would integrate computation and physical processes using sensors, actuators and networks to monitor and optimize energy usage. It describes related existing systems for energy management in buildings and industry. The conceptual model was designed with requirements for low power, scalability and remote control. Potential applications of a CPES include modeling energy systems, improving efficiency in areas like ICT, managing energy resources, and developing new energy control strategies. The document concludes that a CPES could significantly advance national energy efficiency goals through closed-loop control systems.

5. Introduction
Cyber Physical Systems (CPS) and energy efficiency play
a major role in the context of industry expansion.
Management practices for improving efficiency in the field
of energy consumption became a priority of many major
industries who are inefficient in terms of exploitation costs.
The effort of adopting energy management means in an
organization is quite challenging due to the lack of
resources and expertise.
A Cyber Physical Energy System (CPES) that will change
organizations’ way of consuming energy, by making them
aware of their use.

6. Introduction (2)
Reliability, security and autonomy – Due to its scale and
complexity, such a CPES must be robust, secure and
reliable to system failures and changes in the environment.
The CPES should also be adaptable to unexpected
conditions and system failures by the means of predefined
problem resolutions, thus ensuring autonomy.
Comprehensive integration – CPES need to be closely
integrated. They are the integration of computation and
physical processes which relies on embedded real time
systems and network communication infrastructures.
Constrains – Due to the fact that every component of the
system uses embedded software to communicate to other
components, the proper functioning of the system depends
on computing power, resource allocation, network
bandwidth etc.

10. The areas of applicability of a cyber physical energy system relate to:
A) Modeling Energy Systems
The power system modeling is executed by using standard models
based on differential algebraic equations (DAE) which are usually
simplified and divided by time span of the studied phenomena. CPAs
can provide a platform for developing simulation, analysis and design
tools.
B) Energy Efficiency
In the area of energy efficiency within ICT companies, researchers
are studying CPES capable of reducing the power consumption of
computers, servers and wireless devices. Cyber Physical Systems
can play a major role in sensor networks where components require
mobility and an efficient use of battery life.

11. C) Energy Resource Management
To ensure a distributed energy resource management, a Cyber Physical
SCADA system is proposed. This approach would consider resource
generation, storage and usage. Another approach is based on data
centers energy management by finding the best trade-off between QoS
(Quality of Service) and data energy costs. Energy conservation is a
major concern of Cyber Physical Systems.
D) Energy Control
A Cyber Physical Energy System requires the development of special
controllers which address dynamic phenomena describing a wide variety
of behaviors. Some major topics of interest in the field of energy control
address topics.

12. A Cyber Physical Energy System (CPES) provides many
opportunities to greatly improve national energy efficiency and
conservation, also reducing the emissions of greenhouse gases.
CPS are designed and used for a wide variety of domains, also
providing an increasingly significant impact in ensuring a proper
management of energy.
Closed loop voltage control, small-signal stabilization and
decentralized load frequency control are just a few future
directions for research and development in the area of CPES.
