Abstract

Abstract Solar power plant is one of the developments in the use of renewable energy that has received government support through Ministerial Regulation No.49 of 2018 and Ministerial Regulation No.26 of 2021 regarding rooftop solar power plant. Based on the 2019 solar power plant roadmap draft, the investment cost of rooftop solar power plant per kWp is around 14-25 million rupiah, the amount of this investment is an important consideration for the community to install rooftop solar power plant. One alternative to reduce the investment cost of rooftop solar power plant is to reduce the capacity of the inverter by using lighting from DC lamps. This research was conducted by comparing the efficiency values and investment costs, and using the benefit-cost analysis method to compare a series of relevant costs and benefits between the use of DC lamps and AC lamps for household lighting using PLTS. The results of this research is that DC lamps have a light current of 280 – 350 lumens, an illumination intensity of 48 lux, and a PLTS system efficiency of 98,5% which is higher in value compared to AC lamps which have a light current of 250 lumens, an illumination intensity of 21 lux, and a PLTS system efficiency of 49,3% with the same lamp power of 3W. Analysis of the investment feasibility of on-grid and off-grid PLTS, both 2200VA and 900VA shows that the NPV is negative and the BCR value is less than 1, so the investment is not yet feasible. Keywords: Investment feasibility analysis, DC Lamps, AC Lamps, Solar Rooftop

Abstract

The world’s need for green energy is something that cannot be postponed any longer, where the transmission-distribution process requires power distribution in DC voltage. However, currently, the majority use AC voltage, so limited experience and lack of data regarding electrical cable aging under high voltage (HVDC) and their reliability are problems that must be resolved. Crosslinked polyethylene (XLPE) constitutes many insulation cables used today, so estimating the lifetime of DC XLPE cable insulation is urgent research, even though various model-optimization improvements are needed to obtain accurate results. This research begins with pre-processing for the input and output data. These results were then analyzed using two improved model schemes to accommodate the addition of variable space charge and thickness: backpropagation neural network (BPNN) and hybrid BPNN with inverse power model (BPNN-IPM). The learning process uses gradient descent (GD), genetic algorithm (GA), and Levenberg-Marquardt (LM) optimization methods. Finally, the proposed method was verified using experimental data from previous research. The results show that the hybrid BPNN-IPM with LM optimization method is the most accurate: training root mean square error (RMSE) achieved 0 days, and testing RMSE achieved 0.83 days. These results show that the method BPNN-IPM-LM used is most accurate in estimating the lifetime of DC XLPE insulation.
