The design of communication infrastructures for smart DAS and AMI

Information and communication technologies (ICT) play a pivotal role in SmartGrid. However, the current ICT infrastructures do not fully support real-time, secure and reliable communications and do not accommodate requirements of new SmartGrid services. According to that, power utilities do their best to construct upgraded communication networks for SmartGrid. The intent of this paper is to introduce KEPCOs field area network (FAN) architecture and research for smart distribution automation system (DAS) and advanced metering infrastructure (AMI).

Reliable Network Design for Ethernet Ring Mesh Networks

A Novel Design Optimization For Reliable Networking Is Investigated In Ethernet Ring Mesh Networks With The Itu-T G.8032 Ethernet Ring Protection Recommendation. Designing An Ethernet Ring Mesh Consisting Of Multiple Rings To Achieve The Maximum Network Availability Is An Np-Complete Problem. We Show That A Graph With Vertex Connectivity Equal To Or Greater Than Two Is A Sufficient Condition For Designing An Ethernet Ring Mesh. A Novel Design Rule With An Efficient Heuristic Algorithm Is Proposed To Find A Design Close To An Optimal Ethernet Ring Mesh In Terms Of Maximum Network Availability. Compared With An Optimal Network Design Algorithm With An Exponential Enumeration Search Cost, The Heuristic Algorithm Achieves Network Availability Nearly As High As That Of An Optimal Design At A Polynomial Cost.

Study on AMI system of KEPCO

In this paper, we introduce Advanced Metering Infrastructure of KEPCO. This article provides the experience and know-how about AMI trial carried out in 65,000 households. It contains a variety of information related to system architecture, characteristics of developed devices. Also the future plan is presented.
