Distribution network state
estimation provided complete and reliable information for the distribution
management system (DMS) and was a prerequisite for other advanced management
and control applications in the power distribution network. This paper first
introduced the basic principles of the state estimation algorithm and sorted
out the research status of the distribution network state estimation from least
squares, gross error resistance etc. Finally,
this paper summarized the key problems faced by the high-dimensional multi-power flow active distribution network state estimation and discussed
prospects for future research hotspots and developments.
