We know that changing from one technology to another is an increasing problem for network managers, who are faced with the need to move away from outdated technologies, having the responsibility for the migration and the future development of their network.
In recent years, utilities have been prepared for the migration from TDM / SDH / SONET to Ethernet and IP-based applications.
The exponential growth of packet traffic is based on a combination of smart grid automation and “aging” TDM-transportation equipment.
Finding a solution for this need it’s become significant, but before you start the migration process, it is important to decide if the revolution of the network must be total, that means to modify each component of the network, or whether it should be implemented gradually, having a mixed TDM and packet traffic. In both cases, companies have to utilize hybrid Multiservice solutions.
In addition to having access aggregation solutions, power, energy and utility companies have to simultaneously plan a scalable packet backbone. The best solutions for this kind of application are IP/MPLS (IP-Multi Protocol Label Switching) and MPLS-TP (Multi-Protocol Label Switching – Transport Profile).
When we talk about smart grid, we refer to “Intelligent” networks which aim to achieve efficiency in term of generation, distribution and consumption of energy, all orchestrated by a centralized electronic management system. A smart grid is a data communication network, integrated within the power grid and it’s make possible to analyze real-time data about the network and end users, giving the possibility to intervene immediately in case of emergency.
Even in the smart grid, many utilities companies are considering migrating to IP, going from existing SCADA RTU that do not allow you to scale their network capacity, to get to use industrial Ethernet routers or switches.
To achieve a near-real time information collection and distribution, the power grid communication infrastructure needs to migrate to NG networks. But this migration is typically done in stages, meaning that the network solution should support packet and serial interfaces.
Smart Grid application gives power, utilities and energy the means to meet communication challenge, remote data management and monitoring capabilities, automation and control, and the systems for the effective utilization and safe management of transmission and distribution networks.
Smart Grid enable utilities, power and energy to delivery services in a sustainable, economic, efficient ad secure way.
Today the backhauling of distributed automation and smart metering are being used to facilitate a wide range of application in the fields of power monitoring, remote meter reading, customer relationship management, demand-side management and value-added services. Smart meters that enable two-way communication between the meter and the central system are making it possible to engage with consumers in new and innovative ways and to deliver a higher level of customer service then ever before.
