Diponegoro University is one of the universities that support the research, development, and utilization of renewable energy in Indonesia. The Diponegoro educational reservoir is one of the facilities at Diponegoro University that can be developed as a floating photovoltaic. The potential of the Diponegoro educational reservoir as a floating photovoltaic on-grid is 1.846 kWp. Penetration of floating photovoltaic in the power grid can affect the power quality of the system. This paper discusses the effect of floating photovoltaic penetration in the education reservoir in Diponegoro on the 20 kV distribution network using ETAP software. In this study, the penetration of floating photovoltaic capacity connect to the distribution network is 0%, 10%, 20%, 30%, and 40%. Penetration of floating photovoltaic can cause a decrease in power factor and losses in the distribution system. The maximum penetration of floating photovoltaic in the education reservoir in Diponegoro in the 20 kV distribution system is 30% with the injected capacity of floating photovoltaic is 1.121,3 kWp and the power factor in of the network is 0,867. Penetration over 30% can cause the system power factor to be less than the allowable power factor standard.
