Determination of PV Location to Reduce Losses with Mini Hydro Power Plant Connected to Grid

Initiatives to achieve net zero emissions globally began in 2018, including significant efforts in Indonesia. The Indonesian government has set a goal to reach net zero emissions by 2060, with photovoltaic systems comprising 89% of its renewable energy potential. This significant potential poses challenges for national electricity providers, particularly regarding the impact of photovoltaic systems on the distribution network. This study aims to analyze the effects of photovoltaic penetration on a distribution system network with two sources: the Main Substation and a Mini Hydro Power Plant. Additionally, it seeks to determine the optimal location for photovoltaic installations based on real field data. The study concludes with simulation results and discussions on the impact of photovoltaic installations, comparing the system's performance before and after the connection of photovoltaic systems. The simulation results demonstrate that installing photovoltaic systems can increase voltage by up to 5.66%. Furthermore, it shows a reduction in power losses by up to 190%. These findings highlight the importance of strategic planning in photovoltaic placement. This research provides valuable insights into the integration of renewable energy sources into the national grid.
