Abstract

Due to the intermittency and volatility of renewable energy, the system stability is poor and the operating cost is high. This study proposes an economic dispatch model for renewable energy systems based on a demand response model and differential evolution algorithm. A demand response model based on real-time flexible tariffs is combined with charging and discharging strategies for electric vehicles to optimize flexible load dispatch in the system. This combination is intended to improve the efficiency and reliability of grid operation. The traditional differential evolution algorithm is prone to getting stuck in local optima. Given this, this study introduces a deterministic sequence-improved differential evolution algorithm to enhance population diversity and local search ability, significantly improving the global search performance and convergence efficiency of the algorithm. To validate the effectiveness of the model, function extremum and system operation simulation experiments are designed. The results showed that the improved algorithm had a variance of 0 and an optimal value of 10-30 on multi-modal functions, and a variance of 0 and an optimal value of 10-3.5 on fixed dimensional functions. After considering demand response, the peak valley difference in electricity consumption between renewable energy systems A and B was 90.15MW and 527.55MW, with fluctuations of 36.57MW and 201.79MW, and operating costs of 46058.76 yuan and 52.3315 million yuan, respectively. Research findings indicate that the electric energy coordination and economic management of this model have been significantly enhanced. These enhancements effectively ensure efficient energy utilization, facilitate the safe and stable operation of the system, and provide a novel theoretical foundation for the optimization and scheduling of renewable energy systems.

Abstract

This study investigates how physical and mechanical properties affect the performance of triboelectric nanogenerators (TENGs). Polyurethane (PU) was prepared using two methods: (i) one-step PU (non-chain extended polyurethane) and (ii) two-step PU (chain extended polyurethane) via the prepolymer method; both types were filled with different concentrations of nanocrystalline cellulose. Mechanical properties significantly influence the deformation at the material interface that occurs during contact or friction. Key surface characteristics, including surface energy, geometry, and physicochemical properties, affect the effective contact area and potential distribution. One-step PU with 0.1 % CNC demonstrates a maximum capacitance of 29.20 pF, a voltage of 2.04 V, an electric current of 0.43 µA and power of 0.89 µW, representing a 74.5 % increase in power compared to the neat one-step PU, exhibits significant potential for TENG applications. Performance improvements are associated with lower concentrations of cellulose nanocrystals, enhanced hydrogen bonding, and beneficial surface energy. The observed enhancements in output are attributed to improved internal polarization from well-dispersed crystalline nanocellulose, increased crystallinity of the soft segment, and reduced charge transfer mechanisms due to amino groups in the chain extender. However, the impact of the molecular structure and conformation of polyurethanes on triboelectrification remains unclear, highlighting the need for theoretical models and experimental data. This research provides a practical approach for developing stretchable triboelectric materials with enhanced mechanical properties, emphasizing the importance of considering factors such as mechanical parameters, nanofiller content, and surface physicochemical properties to optimize TENG design.

Abstract

This study explores the impact of various geometric modifications, including leading-edge openings, trailing- edge openings, and circular openings, on the performance of the H Darrieus hydrokinetic turbine. These modifications involved the removal of material from a symmetrical NACA0018 airfoil along its surface. The leading edge and trailing edge openings extended from the lower to the upper surface of the blade, while the circular opening was applied exclusively to the upper surface. Using the commercial software ANSYS® V22.2, the turbine was designed, discretized, and analyzed through computational fluid dynamics employing the Realizable K-e turbulence model. The primary output variable measured was torque, from which the power coefficient for each design modification was derived, allowing for the calculation of efficiency in each scenario. Notably, the configuration featuring the upper circular opening achieved the highest efficiency at 51.88% at a Tip Speed Ratio (TSR) of 2.0, a significant improvement over the standard case which had an efficiency of 45.16%. In contrast, the leading-edge and trailing-edge openings resulted in reduced efficiencies of 44.54% and 31.19%, respectively. The enhanced power coefficient of the H Darrieus hydrokinetic turbine with circular openings is attributed to the increased pressure difference generated between the upper and lower surfaces of the blade, surpassing the performance of the standard design.

Abstract

Environmental innovation (EI) plays a critical role in helping a country pursue sustainable development, while green foreign direct investment (GFDI) impacts creative local green innovation. However, there is a lack of research on this link. This paper aims to conduct an empirical investigation into how GFDI affects EI. The estimation findings demonstrate that GFDI has had positive effects on EI—by applying multiple econometric methods, including a panel-corrected standard error modelling (PCSE), a feasible generalized least squares model (FGLS), and autoregressive distributed lag (ARDL) model, to a globally representative sample of 15 European countries between 2012 and 2021. To clarify the connection between GFDI and EI, we present examples of the effects of the latter in both the short and long term. The results show that GFDI has an important beneficial impact on the environment for early-stage investments in the short term. Notably, our findings indicate that GFDI’s long-term effects are more likely to be favourable. Furthermore, we analyze interactions between variables representing institutional quality and the impact of GFDI on EI. Our findings suggest that the positive effects of GFDI may be greater in nations with highly developed institutional systems.

Abstract

Efficient heat transfer significantly improves both the efficacy of photovoltaic (PV) systems and the longevity of PV panels. Lower temperatures facilitate improved power generation and minimize heat-related damage. Conduction, convection, and radiation are the primary heat transfer mechanisms that are involved in this process. This study investigated the effects of PV panel structure heights—specifically 1 meter, 1.5 meters, and 2 meters—on the temperature differences between the top and bottom of the panels, as well as their corresponding power generation, while accounting for the heat transfer that occurred. The PV system comprised nine 540-watt monocrystalline PV panels arranged at these three heights in Khlong Si, Khlong Luang, and Pathum Thani. Data on temperature, power output, and other meteorological variables were collected at 5-minute intervals from 6:00 AM to 6:00 PM over a two-month period from March to April 2024. To evaluate the impact of panel height on performance, all collected data were analyzed. The actual power outputs were compared with simulations conducted using PVsyst. Additionally, the costs associated with each panel height were assessed to identify the optimal height that would achieve both high power output and low costs. The findings revealed that increasing the panel height contributed to a reduction in temperature buildup within the panels and enhanced power output, with increases of 8.87% and 9.45% observed at heights of 1.5 meters and 2 meters, respectively. However, this increase in height also resulted in cost escalations of 24.51% and 48.04%, respectively. Consequently, it was determined that the optimal height was 1.5 meters, as it provided an effective balance between maximizing power output and minimizing costs. Furthermore, the results from the PVsyst simulations indicated significant discrepancies, with measured values approximately 20% lower than expected.

Abstract

A nation's financing system is pivotal in fulfilling the demands of sustainable development. Domestic funding sources and international financial flows make substantial contributions to both economic growth and environmental quality, with their influence being of paramount significance. The objective of this study is to analyze the complex linkage between financial development, renewable energy consumption, technological innovation, on ecological footprint in top remittance-receiving economies, namely Indonesia, Bangladesh, Vietnam, Pakistan, Egypt, Mexico, Philippines, China, and India, over the period 1990-2022. Using Panel Quantile Autoregressive Distributed Lag (PQARDL) method, our findings challenge the universal applicability of the Environmental Kuznets Curve (EKC) hypothesis and reveal complex interactions among variables. The long-term empirical results reveal inconsistent relationships between environmental degradation across different quantiles, challenging the universal applicability of the Environmental Kuznets Curve (EKC) hypothesis. Therefore, financial development reveals a mixed impact on ecological footprint across different quantiles, renewable energy consumption advertises a consistently negative association, suggesting its potential as a sustainable development lever. Moreover, technological innovation's influence varies across quantiles, indicating heterogeneous effects on ecological footprint reduction. Therefore, the validity of an inverted U-shaped or N-shaped Environmental Kuznets Curve pointed complexity of income's impact on environmental outcomes. The validity of the N-shaped EKC in all quantiles, acclaiming that policymakers should incorporating renewable energy and technology innovation into respect when formulating environmental calends.

Abstract

The need for alternative fuels remains a growing concern in alleviating the depletion of fossil fuels for transportation to address one of the objectives of the Sustainable Development Goals (SDG 7: Alternative and Clean Energy) despite the emerging use of Electric Vehicles. Nipa fruticans has been introduced as a promising feedstock for bioethanol production, but its performance as a pure engine engine fuel must be determined, and its carbon footprint must be quantified to assess its impact on the environment were this paper aimed. The CO2 emissions of this study was quantified using ISO 14040 methodologies, considering direct and indirect emissions from production to utilization with key ethanol properties tested according to ASTM standards. A carbureted motorcycle was modified to a fuel injection (FI) system to assess fuel performance, with metrics like power output, consumptions, and emissions were evaluated. Results show that nipa-based bioethanol, H95F and H99F, can serve as renewable pure engine fuels, with carbon footprints of 0.2353 and 2.633 kg CO2eq per Liter respectively with 1.08% lower of kg CO2eq per Liter emissions and 32.7% lower production cost compared to fermented sugar. As pure engine fuel resulted in lowering CO emissions by 171.79% and 167.59%; and lower HC emissions 172.89% and 191.34% respectively compared to E10. These findings demonstrated the potential of nipa bioethanol as a clean and sustainable energy solution. It is recommended however that ethanol yield and distillation process be further improved and explore pure ethanol as alternative fuel to hybrid vehicles as 100% renewable vehicles.

Abstract

Grid-connected photovoltaic (PV) systems face numerous challenges during grid faults, including fault detection, synchronization, over-current protection, fluctuations in DC-link voltage, and compliance with active and reactive power requirements. This paper presents a control strategy based on finite-control set model predictive control (FCS-MPC) to enhance the LVRT capability of these systems. The strategy incorporates a battery energy storage system (BESS) to improve overall performance. Unlike traditional approaches, the proposed method integrates the control of all switches in boost converters, the BSS controller, and the neutral point clamped (NPC) inverter in one controller. It also combines the Maximum Power Point Tracking (MPPT) within a unified multi-objective cost function framework. By utilizing the positive sequence component of the current, this strategy facilitates symmetrical sinusoidal current injection during grid faults, effectively regulates the DC-link voltage, and maintains balanced capacitor voltages in the NPC inverter while avoiding over-current conditions. The BSS plays a key role in energy management by allowing the PV system to continue operating in MPPT mode during grid faults and enabling the storage of excess solar energy during disturbances. This capability ensures compliance with LVRT grid codes by efficiently managing the injection of reactive and active currents into a compromised grid. The proposed method reduces reliance on traditional cascaded hierarchical control loops, enhancing both dynamic response and system robustness during disturbances. The simulation studies carried out in MATLAB/Simulink environment on a 100 kW three-phase grid-connected PV system demonstrate the effectiveness of the proposed approach. The results indicate that the strategy maintains PV system performance at the maximum power point while significantly improving LVRT capability and overall grid stability. According to the simulation results, although in severe grid faults, the negative sequence grid current is kept at less than 1% and the voltage balance of the capacitors in the NPC inverter is maintained accurately. Also, the voltage ripples on the DC-link capacitors are limited to 7% in the fault period. In conclusion, this integrated control strategy effectively addresses the challenges posed by grid faults and enhances the operational efficiency of grid-connected PV systems, thereby contributing to the resilience of renewable energy infrastructures.
