PMU Assisted State Estimation in Distribution System with PV Penetration

The advancement in the field of renewable energy, PV manufacturing technology and power electronics, fast rising energy demand and need of environment friendly energy resources have forced the power industry to switch over for integration of large scale Distributed Generations. This work discusses the effect of large scale solar PV penetration on IEEE-9 bus system. A PV system has been modelled in ETAP and integrated at suitable locations to analyze the effect of penetration on IEEE-9 bus system. Based on steady state bus voltage bus profile and system losses, optimal PV location and maximum PV integration capacity has been identified. Further, a comparative state estimation study is performed on IEEE-9 bus system to show how phasor measurements can enhance the state estimation results over conventional measurements.
