Low voltage network monitoring in RTDS environment

Remotely readable smart meters installed for customers and smart measurement devices developed for secondary distribution substation can be utilized to improve LV network monitoring and management. Today the real-time information about the distribution network state is mainly gathered from the MV network. The paper discusses the extension of the network monitoring and management to the LV level by utilizing the concept proposed by the FP7 European project INTEGRIS. In INTEGRIS concept the smart meters and secondary substation measurement device were connected as part of the LV network. This paper presents the testing of the INTEGRIS concept in RTDS (Real Time Digital Simulator) environment, as well as the testing results to demonstrate how well the LV network monitoring and management could be done by utilizing measurement devices in the secondary substation and in the customer's end.
