“…Energi terbarukan (ET) merupakan solusi efektif untuk tantangan energi dan lingkungan, yaitu transisi dari bahan bakar fosil ke energi terbarukan. Dalam beberapa tahun terakhir, topik penelitian terkait 100% listrik terbarukan telah banyak dibahas (Bin Lu, 2021). Sesuai Peraturan Pemerintah Nomor 79 Tahun 2014 tentang Kebijakan Energi Nasional, target bauran energi baru dan terbarukan pada tahun 2025 minimal 23% dan 31% pada tahun 2050.…”

<p align="justify">enewable energy (RE) power plants can reduce the use of fossil fuel power plants that damage the environment related to CO2 emissions. Solar power centers and wind/wind power plants (PLTB) have intermittent characteristics related to their performance which is strongly influenced by environmental conditions such as fluctuations in solar radiation & wind speed. This creates problems in the stability & reliability of the electricity system so that its utilization is not optimal. Pumped storage hydropower (PSH) is a renewable energy-based technology that can store excess energy production in the electricity system at low load conditions to be distributed when the system is in peak load conditions. This study aims to determine the use of PSH concerning increasing the penetration of RE generators in the electricity system. Pastel & SWOT (Strength Weakness Opportunity Threat) analysis methods were used in this study. From the results of the discussion & discussion, it was found that PSH technology can support the penetration of RE power plants in Indonesia, especially PLTB & PLTS because it can eliminate the intermittency nature of these plants in the electricity system. In addition, PSH is also a mature energy storage medium on a large & economical scale, making it suitable for application in large & complex electrical systems. The strength of PSH is its mature technology, especially from the aspect of its large and economical capacity. The weakness of PSH is related to its utilization depending on the location due to the need for the area to have sufficient water potential with hilly natural conditions (their elevation), and relatively large land. The opportunity offered by PSH is that Indonesia has many areas that have the potential to be developed into PSH. In addition, the use of PSH can reduce the cost of production and increase the penetration of PLTS & PLTB. The threat of PSH is the trend of decreasing storage costs & increasing battery performance.<em></em></p>

Gravitational energy storage systems are among the proper methods that can be used with renewable energy. However, these systems are highly affected by their design parameters. This paper presents a novel investigation of different design features of gravity energy storage systems. A theoretical model was developed using MATLAB SIMULINK to simulate the performance of the gravitational energy storage system while changing its design parameters. A parametric optimization study was also conducted using Taguchi and analysis of variance (ANOVA) techniques for optimizing the energy storage rate. Six parameters were studied; three are related to the piston design (diameter, height, and material density). The other parameters are the return pipe diameter, length, and charging/discharging time. Results revealed that the piston diameter and height are the two most significant parameters for the system performance compared to the other parameters, as they contributed by 35.11% and 30.28%, respectively. The optimization results indicated that the optimal piston diameter, height, and return pipe diameter were 0.25, 0.5, and 0.01 of the container height. The outcomes of this paper can significantly improve energy storage and power generation from renewable energy systems as it provides a reliable, economical, sustainable, and durable energy storage system.

“…An Asia-Pacific supergrid used to supply Southeast Asia with electricity from Australia was analyzed in [16]. More recently, Lu et al [17] discussed and analyzed the role of short-term offriver energy storage for higher penetration of renewable energy (as much as 97%) in the Asia-Pacific supergrid delivering substantial environmental benefits. Wang et al [18] performed a case study on the economic viability of a transmission network in Australasia.…”

This paper aims to evaluate the life cycle greenhouse gas (GHG) emissions of importing electrical power into Singapore, generated from a large-scale solar photovoltaic (PV) power plant in Australia, through a long-distance subsea high-voltage direct current (HVDC) cable. A cost optimization model was developed to estimate the capacities of the system components. A comprehensive life cycle assessment model was built to estimate emissions of manufacturing and use of these components. Our evaluation shows that, for covering one fifth of Singapore’s electrical energy needs, a system with an installed capacity of 13GWPV, 17 GWh battery storage and 3.2GW subsea cable is required. The life cycle GHG emissions of such a system are estimated to be 110gCO2eq/kWh, with the majority coming from the manufacturing of solar PV panels. Cable manufacturing does not contribute largely toward GHG emissions. By varying full-load hours and cable lengths, it was assessed that sites closer to Singapore might provide the same energy at same/lower carbon footprint and reduced cost, despite the lower insolation as compared to Australia. However, these sites could cause greater emissions from land use changes than the deserts of Australia, offsetting the advantages of a shorter HVDC cable.
