Smart Grid using 1st generation AMR meters — An operational view

This paper describes how the DSO Malarenergi Elnät AB has used their 1^St generation smart AMR meters to control the LV network. Due to the early meter regulation in Sweden, Mälarenergi bought their AMR meters in 2006. To fully take advantage of the 1^st generation smart meter functionality to control the LV network, Malarenergi started a project to connect the DMS system with the AMR meters. The benefit is that the control room can monitor the whole operational chain from Substation to customer. This results in better customer service, faster handling, localization and restoration of faults in LV network. The project has also given many valuable experiences regarding possibilities as well as limitations in the existing AMI solution. This will be useful input for Mälarenergi when specifying the requirements for 2^nd generation smart meters and AMI solution.
