Abstract
In the next few years, the home energy management system trend of the smart home will become
increasingly evident. From the application and development of recent years, the Bluetooth and
Zigbee are the most valued by the industry. Of these two kinds of technology, Zigbee supports low
cost and more number of nodes, and with its low power consumption, it is bound to become a ma-
jor communication feature for the smart home technology. Because Zigbee SEP2.0 specification
support multiple network technology features, a product can become compatible with a variety of
communication methods to connect with the home network and achieve home automation of
functional requirements, facilitating maximum performance of wireless applications.

1. Introduction
In modern society, the Internet is an essential element in life like water and electricity. With technological de-
velopment, people no longer just use interconnection equipment for computers. Household appliances, medical
instruments, watches and other devices also need interconnection, which is achieved through short-range wire-
less transmission technology. Other common technologies are infrared, Bluetooth, ZigBee, radio frequency
identification (RFID), and near Field communication (NFC).
With the advent of the age of information technology and consumer demand for high quality and reliability,
power consumption has also increased. At the same time, the pressure to utilize natural resources and the envi-
ronment is also increasing rapidly. Smart grid is a system that combines physical power systems and information
system, which is connected to a variety of devices and information to form an information platform. Smart grid
may add some new technologies in communications, distributed systems, advanced metering, automated storage,
etc., allow a substantial increase in smart home network reliability and robustness, and reduce energy consump-
tion and unnecessary waste of resources.
With the advent of the smart grid, consumers can reduce their home electricity costs and energy consumption.
For this purpose, some related technologies have been proposed [1]-[8]. To use energy management system in

residential areas, smart home devices are used widely. However, for existing appliances, we need to add a data
processor and a wireless data transceiver device in every home. The data processor may analyze the received
data transceiver and allow appropriate operation of the device. These types of home devices have emerged.
Some smart air conditioners can be interconnected with a tablet PC or a mobile phone and can be controlled by
the user. If every household device can be interconnected, each user will be able to centrally control the devices
and reduce energy consumption, thus achieving the goal of a smart home.
2. Smart Grid and Zigbee SEP2.0
2.1. Smart Grid Drivers
The key market drivers behind Smart Grid solutions are [9]:
Need for more energy.
Increased usage of renewable energy resources.
Sustainabilit y.
Competitive energy prices.
Security of supply.
Ageing infrastructure and workforce.
The utilities have to master the following challenges:
High power system loading.
Increasing distance between generation and load.
Fluctuating r enewable.
New loads (hybrid/e-cars).
Increased use of distributed energy resources.
Cost pressure.
Utility unbundling.
Increased energy trading.
Transparent consumption and pricing for the consumer.
Significant regulatory push.
Smart Energy Profile 2.0 [10] can satisfy the functional requirements of the Neighborhood Area Network and
Home Area Network, and provide home automation control, advanced meter reading system (Advanced Meter-
ing infrastructure, AMI) and wisdom metering system (Smart Metering) applications, as shown in Figure 1.
With the development of standardization in SEP2.0, it has been proven to be compatible with multiple net-
work technologies. There is rapid development of this SEP2.0 in the United States. To promote smart grid stan-
dardization bodies (National Institute of Standards and Technology, NIST) and to develop wireless communication

standards for residential appliances, the standard US smart grid interoperability standards framework was com-
pleted in 2009 (Initial Smart Grid Interoperability Standards Framework) and version 1.0 is used in next-gener-
ation grid plans.
2.2. Zigbee Smart Energy Profile 2.0 Features
Smart Energy Profile 2.0 (SEP2.0) adopts the IPv6 architecture and the use of communications technology enti-
ties will no longer be limited to the IEEE 802.15.4. It supports IEEE 802.11. Power-line technology, as shown in
Figure 2, is a breakthrough in the development of network management and features original number of devices
and the transmission speed of the problem, effective power systems and energy use in series end, and the smart
to meet the power system control function planning.
SEP2.0 supports the same physical layer (Physical Layer, PHY) specifications for a variety of network, such
as wireless LAN (Wi-Fi) and Power Line Communication (PLC), etc., and can communicate with each standard
room, and further expand the smart grid control, as shown in the following functional description of each layer.
SEP2.0 layers are shown in Figure 3.
Link Layer:
SEP2.0 is designed to operate in any Link layer technology, and has the following features:
1) Support for all possible physical layers, e.g., IEEE 802.15.4, 802.11 series, 802.3 series, HomePlug and
IEEE P1901.
2) Support wireless communication and power lines wired Homeplug in ESI.
3) Support wired home network (Home Area Network, Han) and bridging of the wireless home network, and
maintain two different kinds of network compatibility.
4) In the Energy Services Interface (Energy Service Interface, ESI), support HomePlug IEEE802.15.4 and
physical layer interface.
Adaptation Layer:
SEP2.0 is designed to run on the IP network. Therefore, it should be able to run on any underlying network,
except for some specific network environment, in order to achieve greater efficiency, performance or reliability.
For interoperability reasons, Adaptation on the layer structure must have consistency.

1) To run on 802.15.4, the 6LoWPAN architecture (IPv6 over Low Power Wireless Personal Area Networks)
must be used.
2) To run on the power line network, IEEE 802.2 and IPv6 architecture should be running.
3) In addition to two or more networks, to run on the remaining network, it must comply with the MAC IETF
Recommendation RFC4919 standards as defined in the PHY layer.
Network Layer:
SEP2.0 must be used for IPv6 on the Network layer network communications, contrary to all the various
energy-saving equipment. SEP2.0 must support the IPv6 architecture (architecture includes the address, address
auto-configuration, Neighbor Discovery function).
Transport Layer:
Because SEP2.0 supports HTTP, it also supports the use of the Transport layer UDP (User Datagram Protocol)
and TCP (Transmission Control Protocol).
Application Layer:
SEP2.0 in the Application layer is divided into two parts, namely business objective technical requirements
and supporting technical requirements. Business objective technical requirements for functionality of SEP2.0
require basic settings; it is recommended that the service equipment have this function. The supporting technical
requirements are for the business objective technical requirements, which are subdivided to provide intelligent
energy standard operating environment necessary for management capabilities. The following section explains
this two-part features and the meaning of their functions.
3. Zigbee SEP 2.0 Applications
Zigbee was applied in the early development of automation and control, such as environmental monitoring, in-
dustrial automation, etc. Global climate anomalies, decreasing energy, aging population and other issues have
prompted the development of networking in home automation (smart home), and wisdom meter and other ap-
plications have become increasingly important.
ZigBee Alliance realizes the wisdom of energy management, and it hopes to develop the specification stan-
dards for manufacturers of related products such as meter (Smart Meter), home energy monitor (In-home Dis-
play) , load controller (Load Controller), and energy gateways (Gateway) so they can communicate; compared
with SEP 1.0, SEP 2.0 supports a broader level, such as the use of IPv6 architecture, supports IEEE 802.11
(Wi-Fi), Powerline (PLC) and other communication technologies to facilitate energy consumption in devices in
series with the power system.
From the application perspective, short-range wireless transmission technology development is a trend not just
for consumers but also for medical care, wearable devices, mobile payments, and finally almost every smart mobile
devices. In order to add more value, these front-end devices for consumer use may require more than one wireless
technology; in addition, size, power consumption and manufacturing costs and other factors are considered. Thus,
integrating a variety of wireless communication technologies in a single chip has gradually become popular.
4. EMC in Sma rt Gr id
Electromagnetic compatibility (EMC) in the smart grid is very important. With reference to the basic EMC
standards, it has detailed measurement and test methods, EMC generic standard specifies the limited number of
essential emission and immunity testing, and the lowest level of the test. The aim is to ensure a good balance of
technical and economic considerations of the compatibility.
The key to smart grid is that it has a “two-way communication” function; the power companies use remote
monitoring systems, understand the electrical conditions around the country, and the deployment of power. The
users can also keep track of their electricity situation, further regulate power consumption, and achieve ener-
gy-saving and money-saving effects.
The basic structure of smart grid is the advanced metering infrastructure (Advanced Metering Infrastructure,
AMI), which is a very important part. AMI is the smart of the meter, two-way communication networks and in-
formation analysis management and controls software, electrical safety protection mechanism and automatic
meter reading control center.
The domestic industry is also actively expanding its products using the smart grid architecture, and while
there is a need to rely on foreign countries to perform the test, there have been smart grid related equipment

manufacturers, which provide exceptional EMC testing in the energy industry in the country, test items are
shown in Table 1.
Services include smart grid applied to all kinds of electronic products, such as the smart of the meter, tele-
communications equipment, information technology equipment used within the plant, and wireless (RF) devi c es.
5. Conclusion
In recent years, smart grid has become popular, and the application of the future will be short-range wireless
transmission of sma rt family wearable electronic device. If combined with Zigbee SEP2.0 standardized features
to support multiple network technologies, and using EMC electromagnetic interference and electromagnetic to-
lerance test, the surface of the product will have characteristics compatible with a variety of communications to
achieve the home networking and home automation functional requirements.
