Abstract

Unbalanced intersectional traffic flow increases vehicle delays, fuel consumption, and pollution. This study investigates the application of deep reinforcement learning (DRL) to optimize traffic signal timing at the Pamelisan intersection in Denpasar, Indonesia. Real-world traffic data were incorporated into a SUMO microsimulation environment to train DRL agents using the deep Q-network (DQN) algorithm. Experimental results show that DRL-based optimization reduced the average vehicle waiting time from 594.49 seconds (static control) to 169.44 seconds and 173.10 seconds for agents trained without and with noise, respectively. The average vehicle speed remained stable at 5.6–5.97 m/s across all scenarios, indicating enhanced traffic efficiency without adverse effects. The findings underscore the effectiveness and adaptability of DRL in addressing traffic inefficiencies, optimizing them, and offering a robust solution for dynamic traffic management at unbalanced traffic intersections in urban areas.

Abstract

The limited availability of fossil fuel reserves and the fact that their formation takes millions of years have driven the accelerated adoption of electric vehicles as a strategic step to reduce carbon emissions. Bali, as one of the leading regions in the clean energy transition, requires adequate infrastructure support, particularly charging stations as the main facilities for electric vehicles, whose development must take into account proper location selection and design. This study focuses on the design and location selection of battery swapping stations for electric motorcycles (SPBKLU) in South Bali, including three-dimensional designs and electrical layouts, as well as location determination using the Analytical Hierarchy Process (AHP) method by evaluating potential sites. The results of this study are one optimal location for SPBKLU installation, accompanied by a three-dimensional design suited to the site’s characteristics and the SPBKLU’s electrical layout. In the future, it is expected to serve as a study and reference for the development of electric vehicle infrastructure in Bali, accelerating public adaptation to this technology.

Abstract

Indonesia is currently in a transition toward clean energy. Therefore, accelerating the adoption of Electric Vehicles (EVs) as a replacement for fossil-fueled vehicles has become a strategic step that is being actively promoted. To support this, the availability of adequate infrastructure is a key factor, with charging stations serving as the main infrastructure for electric vehicles. For optimal operation, the development of charging stations requires proper location selection and design. This study focuses on the design and location selection of Public Electric Vehicle Charging Stations (SPKLU) intended for electric motorcycles in the South Bali region. The design features a three-dimensional model of the charging station, along with its corresponding electrical plan. Meanwhile, location selection is carried out using the Analytical Hierarchy Process (AHP) method by evaluating potential sites. The outcome of this study is the identification of the best location for installing the SPKLU, accompanied by design suited to the site’s characteristics and the SPKLU’s electrical design. It is expected that this work can serve as a study and reference for further development to accelerate the adoption of electric vehicles in Bali.

Abstract

Bali is one of the regions in Indonesia at the forefront of the transition toward clean energy. One of the key steps to achieving this goal is the shift to electric vehicles (EVs). Therefore, the design of electric vehicle charging stations is a crucial factor in ensuring a smooth transition. Charging stations must be strategically located to provide easy access for users, and their planning must comply with existing regulations. One type of charging station is the Public Electric Vehicle Charging Station (SPKLU). However, most SPKLUs are focused on electric cars, whereas the use of electric motorcycles is far more widespread. For this reason, this study focuses on the design of a direct charging system for electric motorcycles, which can be connected directly to the vehicles. The design process includes both 3D modeling and the electrical layout. The selection of a suitable location will be carried out using the Analytic Hierarchy Process (AHP) to determine the optimal site in the South Bali area

Abstract

Bali Province is one of the areas that has abundant renewable energy potential. Through increasing the role of renewable energy in the national energy mix which is a government program, which aims to reduce the use of non-renewable energy and open community participation in utilizing renewable energy in Bali Province. To overcome these problems, an analysis of the investment costs of developing renewable energy plants in Bali Province in 3 scenario modeling was carried out. In this scenario modeling is carried out to determine the investment cost of developing renewable energy plants in Bali Province in the 2024 - 2045 time span. The results of this study show that renewable energy investment costs in the optimistic scenario require investment costs of 264,12 Million USD in 2024 increasing to 2.078,35 Million USD in 2045 with total investment costs during the modeling period of 46.477,10 Million USD. The moderate scenario requires investment costs of 264,12 Million USD in 2024 increasing to 1.186,30 Million USD in 2045 with total investment costs during the modeling period of 27.362,52 Million USD. The pessimistic scenario requires investment costs of 264,12 Million USD in 2024 increasing to 986,80 Million USD in 2045 with total investment costs for the modeling period of 20.817,04 Million USD.

Abstract

The Bali Provincial Government has declared a commitment to achieve Net Zero Emissions (NZE) by 2045. This involves transitioning from non-renewable energy sources to renewable energy to reduce emissions from the energy sector. The policy aligns with the growing demand for electricity and the abundant renewable energy potential in Bali Island. Three scenarios were simulated using the Open Source energy Modelling System (OSeMOSYS) software to evaluate Bali power system with renewable energy potential from 2024 to 2045. The results indicated that to achieve NZE in year 2045, for the optimistic scenario, the renewable energy share may reach 85.62% and result in a reduced emission to 5.78 million tons of CO2eq. For the moderate scenario, Bali Island is required to have a renewable energy share of about 84.13% and 4.15 million tons of CO2eq at the end of year 2045. Meanwhile, for the pessimistic scenario, the renewable energy share must be about 82.65% and with an emission of 3.19 million tons of CO2eq in 2045.

Abstract

This paper presents a model of a batteryless off-grid photovoltaic (PV) system with an adaptive multi-motor load. This model is developed as an effort to enhance the power output of batteryless off-grid PV systems for motor loads. Instead of using a single large-capacity motor, as commonly done in previous studies, the model distributes the load into several smaller motors and controls them adaptively. This approach allows for better control of the total load impedance to support maximum power point (MPP) tracking. A case study involving three three-phase induction motors, each with an operating power of 200 W, is conducted, where the power production of the proposed model is analysed by comparing it with the theoretical MPP and a fixed-load motor system that represents a single large motor. Under 1000 W/m² irradiance and using an 852 Wp PV array, the proposed model achieves a power output of 842 W, which corresponds to 98.83% of the MPP. In contrast, the system without this model only generates 298 W, or just 35.02% of the MPP. The testing process spans a 5-second period during the motor starting state. The power production analysis of the proposed model is presented in graphical form using MATLAB/Simulink.
