To improve the economy benefit of energy optimal dispatching of islanded microgrid (MG) and the ability to deal with the uncertainty of load, the day-ahead optimal dispatching based on improved symbiotic organisms search (ISOS) and the real-time optimal dispatching based on real-time dynamic adjustment strategy (RTDAS) is proposed. The structure of islanded MG based on multi-agent system introduces consumption resistors (CR) to consume excess energy in real-time dispatching. The introduction of recombination and mutation phase in ISOS is to improve the global search ability to obtain better day-ahead optimal dispatching results. Then the RTDAS in real-time optimal dispatching adjusts the power output of batter energy storage system (BESS), micro-turbine (MT) and CR to deal with the fluctuation of actual load. To improve the solving speed of real-time optimal dispatching, the models of BESS and MT are linearized. Simulation shows that the day-ahead optimal dispatching results based on ISOS are better than that based on SOS and the real-time optimal dispatching based on RTDAS can quickly complete the real-time power output adjustment of BESS, MT and CR in about 1 s time. Moreover, the results of real-time optimal dispatching with linearization model of BESS and MT are better than those without linearization.

In order to increase the power generation of wind turbine generator system (WTGS) and extend the service lifespan of the yaw system, this article proposes a control strategy of power increase and lifespan extension for the yaw system based on power loss of wind turbine. Firstly, the traditional yaw system control strategy is introduced, and the relationship between wind speed, yaw angle, and wind power loss is analyzed; Secondly, based on the principle of power increase and lifespan extension control in yaw systems, the power loss of wind turbine and its delay time are taken as control parameters, then a yaw system control model based on power loss control is obtained; Thirdly, in order to simultaneously considering maximum wind turbine power generation and minimize the count of yaw system actions, a dual threshold objective function for the yaw system is constructed, then the power loss threshold and delay time threshold are obtained by using historical monitoring data of wind turbine and genetic algorithm; Finally, the example verification shows that compared with traditional yaw system control strategy and the control strategy based on wind speed interval division, the control strategy proposed in this article can achieve the transfer and allocation of yaw system action count in high, medium, and low wind speed ranges, which can reduce the total count of yaw system actions, and have important application value in improving wind turbine power generation and extending the service lifespan of yaw system.

This study analyzed the energy and carbon impacts of green remodeling initiatives on 20 daycare centers in Seoul, South Korea, focusing on aging public facilities. The findings demonstrate the substantial impact of green remodeling in enhancing energy efficiency and reducing carbon emissions. Notably, energy demand decreased by a maximum of 43 %, while energy consumption was reduced by up to 67 %. Primary energy consumption also saw a maximum reduction of 46 %. In terms of carbon emissions, levels decreased from 376,850.10 kg CO2eq to 103,270.60 kg CO2eq after remodeling, representing a 27.40 % reduction. Energy consumption reductions were observed across multiple categories, including heating, cooling, lighting, ventilation, and renewable energy. The average carbon emission reduction per unit area was 7.09 kg CO2eq, with the highest reduction reaching 23.74 kg CO2eq per square meter. The vegetation replacement effect, equivalent to planting 12,025 trees, underscores the significant contribution of green remodeling to carbon sequestration and environmental sustainability. Additionally, green remodeling contributed 0.03 % towards South Korea’s 2030 short-term carbon neutrality goal and 0.09 % towards the 2050 long-term goal. These results emphasize the effectiveness of green remodeling strategies in aging public buildings and support the need to expand such initiatives to achieve substantial environmental benefits, aligning with national and international carbon neutrality objectives.

In this paper, an optimal solution has been designed for a combined photovoltaic (PV), fuel cell (FC), and wind system. The idea is to manipulate renewable sources to provide clean energy. The main load demand here is supplied by the grid system, and the role of the proposed system is a backup unit. The proposed system has been used to feed the load into a marketplace in Amman Beach, Jordan. The study here aims to the optimal selection of the size of the renewable source to provide minimum total net present cost and to provide a definite number of the drop of energy supply possibility. This study then utilized an improved Metaheuristics algorithm, called Modified Snake Optimization Algorithm to provide an optimization process. A comparison is conducted among the final results of the method and two other methods, including CHS/FA (combined Harmony Search/Firefly algorithm) and PSO (particle swarm optimizer). Simulations are performed assuming a 5.11 MWh average daily load in the research area, 400 kW peak load, and 0.497 loading factor. Simulations show 2 % optimal sizing results for the loss of power supply probability using the proposed MSO algorithm. Changing the grid accessibility ratio from ninety percent (base case) to fifty percent resulted in a growth in the LPSP amount that varies from 3.5 % to 23.5 %. Further, the results show that the cost of energy for the proposed MSO with 0.0461 $/kWh is less than the PSO and CHS/FA. Also, results show better convergence values in 18 iterations than the other algorithms. Experiments showed good efficiency than other comparative methods when it comes to convergence time, system size, and cost of production. Finally, the implementation of the proposed algorithm to optimize the studied hybrid system can achieve superior and competitive results; (e.g, achieving a lower energy cost compared to PSO and CHS/FA algorithms).

High-intensity large LED displays are prevalent in outdoor advertising lighting and account for a significant portion in building energy consumption. However, the accurate measurement of their power usage is challenging, since it varies with the display outputs. Typically, for tunable multi-spectral LED displays, different light colors and luminance correspond to different energy consumption, but the exact relationships are not clear. This study investigates the energy consumption of LED displays under a series of spectral settings. We collected hyperspectral data from LED display modules under different display conditions, analyzed the correlation between display spectra and energy consumption estimations, and established mapping relation between color and energy consumption. The results show a great linearity and additivity between energy consumption and the radiance of each color channel. We extend these correlations to display colors under different luminance. This work also proposes a convenient energy consumption metric to address the estimation issue of multi-color display outputs, with an average error of 2.52%. This work provides a convenient and non-destructive method for measuring the energy consumption of LED displays, significantly reducing facility management costs in urban commercial districts with numerous displays, and thereby facilitating a balance between urban development and environmental monitoring.

The integration of solar photovoltaic (PV) modules with building facades offers a sustainable solution for generating clean energy and enhancing architectural design. Both PV facades and PV shadings are Building Integrated Photovoltaic (BIPV) products that can be utilized to achieve net-zero buildings. In addition to energy performance metrics, aesthetics are equally crucial considerations in integrative photovoltaic design. Expeditiously approximating and optimizing projected energy yields attendant to integrative photovoltaic implementation during formative design phases would meaningfully support the evolutionary process. This study explores a combined solar facades system, consisting of colored opaque facade-integrated photovoltaics (FIPV) attached to the building’s walls and passive solar shadings. This research first employs regression methods to model the shading impact on solar radiation and then uses a parametric approach to evaluate and optimize the combined solar facades system on the facade of a high-rise residential building in Hong Kong. Furthermore, the effects of geometric and color parameters of solar shadings and solar walls on the energy efficiency and total power harvesting were analyzed. In conclusion, a combined solar facades system shows promise for net-zero energy buildings. Opportunities to refine integrated CAD 3D modeling and simulation tools were noted to further optimize design decisions for BIPV projects in the early design stage.

Environmental impact, energy efficiency and cost optimization are basic aspects when selecting heat transfer fluids (HTF) for CSP plants. The present study evaluates the environmental impact of four CSP HTF types (Thermal Oil, Liquid Metal, Molten Salt and Silicone-based), by analyzing different traditional and innovative fluids, such as Therminol VP-1®, Liquid Sodium, Lead-bismuth eutectic, Solar Salt, Hitec®, Hitec XL® and Helisol® 5A. All fluids underwent a life cycle analysis with the ReCiPe 2016 method, using the Ecoinvent 3.8 database, the SimaPro 9.3 software and the “cradle-to-grave” perspective to detail their impacts on Human Health, Ecosystem Quality, and Resource Availability. For the hypothesized scenario, results show how Hitec XL® presented the lowest cost and environmental impact values (1.19 US$/kg and 104.99 mPt/kg), being up to 3.6 times more sustainable. Therminol VP-1® obtained the highest environmental impact score, being up to 88.5% more unfavourable than Hitec XL® and 73.4% than the rest of fluids. The area with the highest impact was Human health (92.54%), with a significant influence of the Fine Particulate Matter formation category (40%). The knowledge developed will provide a detailed insight into the environmental impact in CSP plants, complementing current performance data and contributing to the energy sector’s decarbonization.

Despite the global momentum toward transportation electrification, there is still a notable lack of comprehensive literature specifically addressing the electrification of bus transit systems in public transportation. In this study, we conduct an extensive review of 458 peer-reviewed articles published over the past three decades (2004–2024) that focus on the electrification of bus transportation. This review follows the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) methodology. Additionally, it is structured using the Antecedents, Decisions, Outcomes (ADO) framework and the Theories, Contexts, and Methods (TCM) framework to organise content and shape a future research agenda. This article contributes significantly by synthesising existing knowledge, identifying gaps in current understanding, and offering directions for future research. The antecedents are classified into four categories: stakeholder, situational, contextual, and psychological factors. The decisions surrounding electrification are analysed in terms of intentions to adopt, transition, procure, and use electric buses. Moreover, the outcomes of electrification are thoroughly examined from environmental, economic, social and infrastructural perspectives. Our study offers valuable insights for policymakers and researchers, deepening the understanding of the challenges and opportunities in the electrification of public bus transportation.
