New methods for distribution network monitoring with smart meters - verifying data in network information systems

There is an economic pressure on distribution network operators that increases the emphasis on optimizing investments and operations. A prerequisite for optimization is a correct evaluation of the status quo. This paper presents one of several possible new methods to increase observability in the distribution network. This method, which combines voltage and power measurements at all end-user connection points, will give valuable feed-back on the quality of network documentation and measurements. The method has been tested with promising results. However, there are limitations to its application. Further evaluations and tests should be performed to determine to what degree it can provide value to the companies in practice.
