Applied stochastic network state estimation

In the year 2000 the proof of principle for Stochastic State Estimation (called Pseudo Monitor) was demonstrated in cooperation with a Dutch utility. Motive of this network company was the decision to construct a data base for monitoring all MV feeders in the substations and prove the important monitoring capabilities of this application for operative and asset management of the network. The main problem turned out to be the collecting of load profiles. In this paper the application of gathering and appointing load profiles of the network are placed in a structure and supported by mathematical definitions. In a second demonstration project more basic know how and skill on load profiles were developed. Experience on standard profiles should be gathered before implementation of these applications in network companies will take place. This paper will reach practical solutions and invite companies to communicate about the desired future research.
