Analysis of Distributed Geographical Locations Impact on Intermittency Reduction of Solar Power Plants in Java, Madura, and Bali, Indonesia

To meet its energy demands, Indonesia is taking on an ambitious initiative to broaden its solar power plant portfolio. Despite this, apprehensions persist about how the sporadic nature of solar power supply could impact the system. By exploring the role of distributed geographic location in reducing aggregated intermittency, this study assesses the potential impact and capacity of solar power plant installation that can be integrated into the grid. In order to perform the research, 54 measurement equipments are dispersed among the islands of Java, Madura, and Bali. By applying the Power Spectral Density (PSD) technique, this study evaluates the potential of these irradiation data to minimize intermittency. Then, to illustrate the resulting improvement, this study calculates solar power plant capacity that could be connected to the Jamali grid. According to our findings, inter-connecting 54 locations decreases the intermittency by 37 to 78% percent, depending on the fre-quency, and yields an aggregated intermittency of 3%. This would allow up to 6.67 GW of solar power plants spread across 54 locations.
