Abstract: Nowadays, when largescale integration of solar PV system takes place at that time the voltage stability plays crucial role in system operation and it has severe impact on the large scale renewable grid connected system. This paper emphasize voltage stability issues in grid interconnection to solar PV system.
This paper investigated the impact of large-scale solar-PV generation on long-term voltage stability. A rigorous theoretical analysis was performed with a simple test system to compare the LTVS impact of the solar-PV generation with the SG. Then the Nordic test system was used to conduct a system wide LTVS study with solar-PV generation.
The short-term voltage stability study presented in concluded that voltage instability could be prevented by operating the solar-PV system at the leading power factor mode during the steady-state.
According to Fig. 23 when relatively less loaded SGs are replaced by solar-PV units with same active and reactive power dispatch it has helped to improve the long-term voltage stability. 5.2.
The dynamic QV curves were used to demonstrate how power system approaches its voltage instability point during the LTVS phenomenon. The solar-PV system performance for LTVS is compared with the SG, and key influential parameters of the solar-PV system affecting voltage stability was analysed.
