Decreasing the implementation costs of smart metering systems with interoperability

Abstract

This paper describes the importance of the interoperability in smart metering systems for modern distribution system operators. The lack of interoperability significantly increases the costs of smart metering system implementation for distribution system operators, especially the costs of purchasing new equipment. The replacement, cleanup and maintenance of electricity meters produced by different manufacturers, which are not interoperable, are also much more complex and expensive. Furthermore, without the interoperability, the system cannot be observable, i.e. the observability exists only for some particular segments of the system. This prevents many functionalities of distribution management system. In terms of interoperability, smart metering systems have gone through four different stages. A comparison of the system implementation costs for these four stages is presented for distribution system operator of Serbia.

“…Therefore, it is important that standardized communication protocols are used throughout the system as this also significantly reduces the price. This was also shown by the experience from the implementation of the smart metering system [30]. Even 20 years ago, many cost benefit analyses showed the technical and economic justification of installing this system in households as well.…”
