The Role of Digitalization in Facilitating Renewable Energy Transition and Reducing Greenhouse Gas Emissions in Thailand
(2026-02-01)
Chaveesuk, Singha

The study investigates the dual transitions of digitalization and renewable energy in Thailand to see if digital expansion facilitates the transition to renewable energy sources and greenhouse gas (GHG) mitigation. The study utilized data from the World Bank between 2000 and 2023 to reconstruct models for autoregressive distributed lag (ARDL) analysis for short-run and long-run dynamics under ecological modernization and technology diffusion theories. Contrary to expected synergies, empirical results revealed that a developing economy would find an ‘investment trade-off’ instead. Digitalization showed no significant immediate impact on renewable energy production; however, it exerted a significant negative lagged effect (coefficient = −0.593), suggesting that digital and energy infrastructures compete for limited financial resources. It was found that there is a 6.3% increase in greenhouse gas emissions for every 1% increase in internet usage. Thus, these results challenge the belief that increased internet usage will help improve the environment. Absent proper supportive policies about both digitalization and green transitions, such as investing in plants and machinery towards digitalization rather than green technology, the pacing effects of digitalization will affect the goals of converting to clean energy. This requires a policy coordination approach to ensure that funds earmarked for green infrastructure are safeguarded.

The ultimate goal of this research is to create effective and environmentally friendly biochar briquettes from oil palm frond (OPF) waste. Red clay, a plentiful local resource, has been demonstrated to improve the properties of fuel briquettes. In this study, the tested composite briquettes (biochar:red clay:starch by weight) were prepared in the following ratios: 40:55:5 (T2), 50:45:5 (T3), 60:35:5 (T4), and 70:25:5 (T5), while the control sample (T1) consisted of 95:5 (biochar:starch). All of the different ratios were analyzed using proximate analysis. The results showed moisture content ranging from 7.35% to 8.47%, ash content from 29.75% to 49.82%, volatile matter from 15.63% to 17.47%, and fixed carbon from 25.31% to 46.48%. Among them, T4 exhibited the lowest moisture and ash content and the highest calorific value at 5,650 cal/g, making it the optimal candidate for further investigation. A comprehensive analysis of T4 was conducted using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). The techniques revealed the morphological structure and inorganic components that contribute to the energy efficiency of T4. The study also examined air pollutant emissions. T4 produced lower emissions of pollutants such as carbon monoxide (CO), carbon dioxide (CO<inf>2),</inf> total volatile organic compounds (TVOCs), formaldehyde (HCHO), and particulate matter (PM<inf>1.0</inf> and PM<inf>2.5</inf>) compared to the OPF biochar briquette without red clay (T1). Composite biochar briquettes made from OPF and red clay (T4) are safe and suitable for use as a fuel source for household applications like cooking and heating. This research contributes to the development of the green bioeconomy and supports sustainable energy initiatives.

A major challenge in distribution systems is the issue of voltage drop along the distribution line resulting from an increased load capacity connected to the utility. A significant voltage drop can affect the performance of a distribution system and cause quality issues for end users, impacting the system’s long-term sustainability and reliability. Therefore, regulations have been set stating that the voltage level should not be more that 5% higher or lower than the rated voltage. Thus, in this study, we aimed to evaluate the voltage level characteristics of a 22 kV distribution system that replicates the actual distribution system in the Provincial Electricity Authority. A voltage improvement technique based on distributed generation placement was proposed. In addition, the distribution system characteristics with and without distributed generation placement were evaluated under fault conditions. The results indicate that distributed generation placement in the distribution system can improve the voltage level along the distribution line. However, the level of increase in voltage depends on the size of the load, the capacity of the distributed generation, and the location of the distributed generation system on the distribution line. Furthermore, placing a distributed generation system with a minimum capacity at the proposed location can improve the voltage within the utility’s standard level. Thus, the installation of a distributed generation system in the distribution system is beneficial in terms of voltage improvement in the distribution system and provides the power system with a sustainable method to address the issue of voltage drop.

Thailand is experiencing significant growth in renewable energy sources, such as solar power and wind power. This growth is leading to an increase in independent electricity trading across public, private, and household sectors, making Thailand the origin of third-party access to electricity in the country. However, the current transmission infrastructure is struggling to keep pace with this development, making it challenging to assess regional transmission capabilities accurately. Furthermore, the rapid urban and industrial growth has also resulted in a significant increase in electricity demand, emphasizing the urgent need for a robust transmission and distribution network. To address these challenges, a paper is currently underway to model the remaining transmission capacity in Thailand's regions using real data and sophisticated electrical engineering software. This analysis primarily concentrates on Available Transfer Capability known as ATC, which draws insights from various methods used in the Indian case study. The goal is to enhance the utilization of the transmission system, support independent electricity trading, and guarantee the stability, security, and reliability of the power system in line with the changing electricity market.

Solar cells are a very popular renewable energy source in Thailand today. In general, there are 2 types of solar cells that have different functions and prices. Monocrystalline and polycrystalline solar cells are compared to study suitability for use in Thailand. Both solar cells are tasked with supplying power to two different loads: a lamp and a motor. Voltage, current, and power are measured in order to ascertain the solar panel's power supply characteristics and take into account the usage patterns of each type of solar cell to accommodate Thailand's solar conditions. Each type of solar cell responds to different power distribution characteristics. However, the load power should therefore be taken into account when determining which solar cell type to utilize.

The purpose of this study was to evaluate the consumers’ adoption of renewable energy in Poland. The study focused on finding out the factors that influence the adoption of the technology, considering its importance in conserving the environment. The study was conducted using a quantitative method, with primary data collected from 467 households using renewable energy technology in Poland. The research adopted the TAM model. The independent variables of the study included renewable energy initial cost, environmental concern, risk and trust for renewable energy, ease of use, financial incentives, and relative advantage. The dependent variable was renewable energy adoption. Structural equation modelling (SEM) was used to analyze the study hypotheses. The research found out that environmental concerns, ease of use, financial incentives, and relative advantage have a positive and significant influence on adoption of renewable energy technology in Poland. However, renewable energy initial cost and risk, and trust for renewable energy did not significantly influence renewable energy adoption. The study recommended that the stakeholders should consider the aspects of environmental concern as a key role player in pushing for adoption of renewable energy. The government, non-governmental organizations, and concerned stakeholders should consider giving incentives towards renewable energy adoption. Creating awareness regarding the benefits and strengths of renewable energy should be prioritized to the households.

Coordinated Control of Electric Vehicles and Renewable Energy Sources for Frequency Regulation in Microgrids
(2020-01-01)

A Control technique of electric vehicles (EVs) cooperating with ac microgrids is considered as an important role with integration of renewable energy sources (RES), i.e. wind and solar farms. As known, the intermittent power generations of these RESs can provide significant changes of the frequency in microgrids. Consequently, outputs of these generations are regarded as continuous disturbances. Previously, the ability to permit frequency stabilizing effect was usually neglected in microgrid design; thereupon, the performance of controller may be ineffective to regulate the frequency in such a microgrid. To address this problem, a new coordination of EV, wind farm (WF), and photovoltaic (PV) for microgrid frequency regulation is proposed in this article. In the control design, the proposed adaptive PI controller is developed by using practical proportional integral (PI) controllers. An effect of a small delay is also considered in input-output pairs of the adaptive PI controllers. Simulation model is developed for validating the proposed controller. Simulation results demonstrate that the proposed coordinated control technique of EVs, WF, and PV power generation provides a better frequency regulation performance than a fixed PI controller under various uncertainties such as wind and solar power fluctuations, N-1 outages, disconnection of RESs, load variations, and the number of EVs.

Dimethyl ether synthesis from methanol over diatomite catalysts modified using nitric acid was investigated. The catalytic performance of diatomite was tested in a fixed-bed reactor under atmospheric pressure and within the temperature range of 250–350°C. It was discovered that high acidity of the catalyst yielded a higher methanol conversion rate. Moreover, it was revealed that the acidity of the catalyst surface was controlled by Al(IV) ions whereas basicity of the catalyst surface was determined by Al(V) and Al(VI) ions. From this finding, the authors were able to propose the mechanism of DME synthesis from methanol over treated diatomite.
