Abstract

The interconnection of renewable energies increases the complexity of modern power systems. Hence, stability assessments should be made to ensure the system’s stability after penetration. Solar power is a type of renewable energy that has become a widespread energy source among renewable energy sources. About 1 MWp of the solar power plant has been prepared to be interconnected to the IEEE 8 bus of Manokwari grid, and this paper investigates the voltage profile, power losses, and stability of the solar power plant penetration using an adaptive kernel density estimator (AKDE) and compares it to a Monte Carlo simulation (MCS)-based probabilistic load flow (PLF). About 5000 samples have been used to test the grid after the connection. Results of simulations show that the solar penetration can reduce power losses from 0.4084 MW to 0.3080 MW and 0.3045 MW by the proposed method and MCS method, respectively, and further increase the bus voltage profile. The power network has the stability to be connected to solar power, as indicated by the small stability index values of each bus. The proposed method using the AKDE method has a more accurate result in stability indices indicated by small fast voltage stability index (FVSI), line stability index (Lmn), and line stability factor (LQP) indices.

Abstract

The demand for electrical energy needs is always projected to increase by 2,214 (TWh) in 2050 or an increase of 9 times compared to the previous years of 254.6 TWh, it's just that current energy needs are still dominated by non-renewable energy which has limitations and does not require energy. environmentally friendly. Therefore, renewable and environmentally friendly energy sources are needed. Utilization of solar energy which is converted into electrical energy is a solution to reduce the use of non-renewable energy. The average daily solar radiation in Indonesia is 4.8 kWh/m². The purpose of this research is to design PLTS Rooftop at the Rectorate Building of the Papua University using helioscope software and to analyze the estimation of electrical energy savings. In designing, using 198 Tallmax TSM-PD14 320 Wp solar modules, SMA Sunny Tripower 20000TL-US brand inverter with a capacity of 4 units (20kW) and an AC Combiner Box containing protective equipment. The simulation results show that the highest electricity production was in May at 8,031.50 kWh and the lowest was in February at 5,997.60 kWh. So from the calculation, the estimated average electrical energy savings is 18%
