Abstract
The Indonesian government targets Indonesia to have zero emission energy by 2050.Solar energy is one solution to this target.The issuance of the Minister of Energy and Mineral Resources Regulation Number 26 of 2021 concerning Rooftop Solar Power Plants opens up opportunities for increasing the capacity of the energy mix from solar energy.However, solar power plants have weaknesses such as low efficiency of solar modules and non-linear power output of the module.This study proposes ANFIS MPPT design as a reference to obtain the maximum power that can be given to a rooftop solar panel system connected to a single-phase grid.The network voltage level is 220 V rms.This study uses 800-pairs dataset for input and output.The inputs of the ANFIS MPPT are radiation and temperature, and the output is reference voltage.The results by using Simulink simulation show that changes in irradiation are followed by changing in the power output of rooftop solar panels.For a load of 5 + j2 kVA, at high irradiation the rooftop solar panels provide greater current to load than at low irradiation.The current from the grid flows to the load based on difference between the load current and current from the rooftop solar panels.
