State estimation of distribution network

Abstract

State estimation is a way to provide adequate network models for online monitoring and analysis purpose. With the integration of many Distributed generations and involvement of many new advanced technologies in distribution network makes it very complicated and more distribution automation will be required. Distribution system State estimation (DSSE) is often a big task due to lack of real-time data availability at many nodes and it leads to use of pseudo measurements. In this paper, Distribution system State estimation (DSSE) involves pseudo measurements due to limitation of real-time measurements at some nodes. Also, by taking load model into account. State estimation (SE) has been enhanced at some extent. This proposed State estimation (SE) results are verified with the help of MATLAB software to validate state variables.
