Abstract
This paper presents a new method in determining the optimal location of Photovoltaic (PV) based on the location's irradiance from SOLARGIS and network system for voltage stability improvement and losses minimization. The analytical method is developed based on the Continuation Power Flow (CPF) which is an assessment to analyze the voltage stability in quasistatic technique. To optimize the allocation process, firstly, areas which have good irradiance based on SOLARGIS will be selected and only those areas will be the input data on the determination of optimal PV placement where PV-Sensitivity of each of these buses will be calculated. The bus that has the highest PV-Sensitivity is a bus that has a good sensitivity to improve the voltage stability of the system as well as has good irradiance and will be recommended for optimal PV placement. Simulation results on the Southern Sulawesi power system show that this method is effective in determining the PV location. In this work, voltage magnitude and network losses are evaluated to compare the stability for each PV placement scenarios. This study provides locations who have good irradiance and PV-Sensitivity, which the results of this research can become recommendations for the power system utility or PLN in Indonesia in planning for PV integration.
