Introduction

• As the power consumption issue is getting important, wise power control system is needed.

• Smart Grid: A smart, self-healing electric power system. [1]

• Despite of the development of Smart Grid, there lacks a general mechanism.

• We utilize SIP and SNMP as management mechanisms in Smart Grid.

Introduction Cont.

• Most of managing interfaces are still proprietary.[2]

• As Smart Grid becomes an important issue, we need a efficient and general solution.[3]

• SNMP has been widely used in network management, SIP is newbie in this field, however, some people take SIP as the clear choice for Smart Grid communication.[4]

Introduction Cont.

• NAT is the issue in the remote management. [5]– SNMP has no register, hence, SNMP request will

be blocked by NAT if SNMP server is in remote network.

– SIP provides register, thus, end-devices register to the remote SIP proxy server and user agent can send request to end-devices via SIP proxy server.

Introduction Cont.

• Smart Grid management is a new field to SNMP and SIP, evaluate the advantage and disadvantage of these two management mechanisms are needed.

• Internet Protocol– IPv4

– Ipv6

• Simple Network Management Protocol (SNMP)

• Session Initiation Protocol (SIP)

System Architecture

• Smart Grid is two-way communication between the consumers and suppliers, in order to achieve two-way communication, this thesis design a small Smart Grid.

• Consumers is available to communicate end-devices with mobile devices, and end-devices send back information to consumers or suppliers for analysis.

System Architecture Cont.

• We porting SIP and SNMP onto end-devices, design several events that will be used in Smart Grid network management.

• Evaluate the performances of two protocols and analyze the differences between two different protocols.

• In this thesis provides the evidences of network management in Smart Grid.

Implementation

• DMA-2440L Platform Porting– Samsung ARM9 Series, S3C2440 Processor

– Kernel: Linux 2.6.24• Enable IPv6: #make menuconfig

– File System: Cramfs• Using Busybox builds Cramfs file system

– Cross compile: Using cross compiler cross compiles the libraries and programs, including SIP and SNMP.

Experiment

• SNMP and SIP can do the same things– Uptime

– MAC

– System Description

• Evaluate the performance of packets transmission– Limited time: Evaluate how much requests of SIP

and SNMP can be sent in limited time.

19

National Chi Nan University

Experiment Results

• SNMP– Advantage: Small packet size

– Disadvantages: Hard to read OID, NAT traversal

• SIP– Advantages: Easy to read contents message, no

NAT traversal problem, better scalability

– Disadvantages: Heavy packet size

Conclusion

• Despite the rapid growth of Smart Grid, without a general management mechanism slows down the development.

• Both SNMP and SIP are mature protocols in their original design concept.

• In this thesis introduces two feasible mechanisms in Smart Grid management.

Conclusion Cont.

• In the last part of this research, providing the following information– Evaluation of performance

– Advantage

– Disadvantage

23

Future Work

• Stream Control Transmission Protocol (SCTP) support– SIP is available

– SNMP is unavailable

• Compression the heavy header of SIP will provide an efficient mechanism.

Smart Grid

• Like the power grid, the smart grid also delivers electricity from suppliers to consumers.

• However, it uses two–way digital technology to support communication between consumers and suppliers.

• It combines power systems, telecommunications, smart energy devices, information technology, and digital control.
