Optimal scheduling of electricity-hydrogen coupling virtual power plant considering hydrogen load response

With the rapid development of hydrogen production by water electrolysis, the coupling between the electricity-hydrogen system has become closer, providing an effective way to consume surplus new energy generation. As a form of centralized management of distributed energy resources, virtual power plants can aggregate the integrated energy production and consumption segments in a certain region and participate in electricity market transactions as a single entity to enhance overall revenue. Based on this, this paper proposes an optimal scheduling model of an electricity-hydrogen coupling virtual power plant (EHC-VPP) considering hydrogen load response, relying on hydrogen to ammonia as a flexibly adjustable load-side resource in the EHC-VPP to enable the VPP to participate in the day-ahead energy market to maximize benefits. In addition, this paper also considers the impact of the carbon emission penalty to practice the green development concept of energy saving and emission reduction. To validate the economy of the proposed optimization scheduling method in this paper, the optimization scheduling results under three different operation scenarios are compared and analyzed. The results show that considering the hydrogen load response and fully exploiting the flexibility resources of the EHC-VPP can further reduce the system operating cost and improve the overall operating efficiency.

Increasing performance of chiller systems in high-rise buildings by load optimization

Recently, the construction of high-rise buildings has been increasing significantly along with economic growth. Therefore, electricity is also going up due to the energy demand of the building. The air conditioning system is the enormous energy consumption in high buildings. The green building concept has been introduced regarding the energy efficiency of a high-rise building. This study investigated the energy consumption in a high building (47 floors) using the load optimization method for the chiller system. The load optimization was conducted by configuring five chillers systems consisting of integral compressors, cooling towers, and pumps. This study obtained the decreasing energy consumption by the chiller's operation load sequencing based on 24-hour data optimization. Optimized chiller performance satisfied the green building standards. However, load optimization on high buildings is highly recommended as an effective way to achieve green building status. Further research is recommended for implementing such optimization at other facilities, such as industrial plants, hospitals, airports, and manufacturing plants.

Green Building Rating of High-Rise Buildings in Sri Lanka


 
 
 As a result of urbanization, constructions of high-rise buildings become a major component of urban development. Constructing high-rise buildings contributes to social, economic and environmental development as well. There are many stages of construction including planning, designing, procurement and implementation. There is a wide range of sustainability practices which can be implemented in each stage of construction. In leading Sri Lanka to Sustainable Development, the green building rating system was introduced by National Green Building Council of Sri Lanka in 2002. This rating system has 100 total points and minimum of 40 points is required for green building certification. The rating system has different components. Among them sustainable sites category includes 25% of total points in green building rating system. This research study highlights the significance of sustainable sites category in order to award the green certification in green building rating system. For this research five major high-rise building construction sites in Colombo were selected and existing site selection practices of each site were investigated. Each site was visited and in-depth discussions were carried out with the planning engineer and other people in the construction site. The structured questionnaire was filled and scores were given accordingly where they have met the sustainable sites criteria. Two sites out of five could not earn single point as they did not fulfill the prerequisites of the site section category. The rest of the sites (three) earned 20, 19, and 18 respectively out of 25 points. In this study, lack of awareness in sustainable site selection practices has dropped the chances of being eligible for the green building certification. Since the minimum points required for green building certification is 40, buildings which are under planning or pre-construction stage have higher chances of obtaining silver, gold and platinum awards for green building certification. Therefore, sustainable sites category of the green building rating system contributes significantly to increase the score and therefore it is highly important in green certification & sustainable construction.

An Analysis of the Relationships between Social Capital Levels and Selected Green Economy Indicators on the Example of Polish Voivodeships

This article presents the results of a study analyzing the relationships between social capital levels and the green economy in Polish regions. By linking these concepts and examining the relationships between them, the study can offer valuable insights for promoting the development of social capital and the green economy. Social capital drives individual growth, and sustainable development plays a key role in this process by improving the quality of life and well-being at a level that is permitted by the current level of civilization. Therefore, social capital is a key prerequisite for sustainable development because it regulates the environmental impact of economic growth and lays the foundation for future development. Trust, openness, and the willingness to cooperate contribute to high levels of social capital, and they are essential for pursuing the common good and preventing the misuse of shared resources. The green economy concept paves the way to sustainable development by improving well-being, reducing environmental risks, and preventing resource depletion. The aim of this study was to identify and describe the relationships between social capital levels (measured based on the main criterion and indirect criteria, including public moral norms, engagement and social bonds, and social trust) and selected green economy indicators on the example of Polish voivodeships. The study involved Polish voivodeships, and data for analyses were obtained from statistical databases in the public domain. The analyzed phenomena are complex and multi-faceted, and they were measured with the use of composite variables. Composite indicators were determined with Hellwig’s method. The study revealed low levels of the examined phenomena and considerable differences between Polish regions. Social capital (main criterion) and engagement and social bonds (indirect criterion) were significantly correlated with the composite measure of a green economy. These results indicate that high levels of social capital can contribute to the growth of integrated, stable, and rapidly evolving communities that are able to effectively cope with the challenges of the green economy transition.

In this article, it can be said that Green's function is considered based on Lagrange's formula for the third-order differential equation with boundary conditions and its conjugate.

A new five-factor green pricing model in China

ABSTRACT We construct the green factor in China based on the premium of the green concept stocks. Replacing the investment factor in the five-factor model with the green factor, we propose a new five-factor green pricing model. We find that the green risk premium is significant in China’s stock market: portfolios constructed with green stocks outperform those constructed with non-green stocks by 3.4% to 3.7% annually. Moreover, the green premium cannot be explained by other factors. Our five-factor model strongly dominates the four-factor model without the green factor and the five-factor model. For the 25 size-EP (size-ROE) portfolios, our five-factor model yields lower GRS statistics and lower average absolute alphas than the other models. Results of Fama-Macbeth regressions also support the superior performance of our five-factor model.
