Phasor Measurement Unit (PMU) Based Monitoring and Management for Medium Voltage Network Integrated with Distributed Energy Resources

This paper presents the phasor measurement Unit (PMU) based monitoring and management which is suitable for medium voltage networks that will have significant distributed energy resources (DER) integration. Its fundamental technology, its application, and its benefits to distribution networks were described. This included the differences between PMU compared to conventional supervisory control and data acquisition (SCADA) systems which are currently deployed in the distribution network. The research trend on this technology application is also surveyed and discussed. The pilot demonstration project on PMU-based monitoring and management, which is currently ongoing at one of the medium voltage level distribution systems in Qatar, is also presented. The experience of planning, installing, and commissioning the system is shared. Highlight of the capability and performance of this PMU monitoring system is also commented on.
