The large increase of distributed generation (DG) of photovoltaic (PV) systems in low voltage (LV) grids results in increasing voltage magnitudes and line loadings. Due to a lack of network observability in present LV grids, distribution system operators (DSOs) cannot detect and respond to any limit violations. Even with data collected by the expected rollout of smart meters, full network observability will not be achieved. Thus, the network state will not be completely known. LV-State Estimation (SE) in combination with pseudo-value generation can provide a way to determine the required network states with respect to voltage magnitudes and line loadings. This paper presents a linear three-phase LV-SE approach computed in phase sequences. The performance of the presented SE approach was investigated on a realistic grid model for different cases with and without pseudo-values. The performance is promising and the approach can be used to provide DSOs with input data for control actions to avoid limit violations and thus will contribute to the further integration of DG.
