Abstract:

<abstract> <p>The electricity demand has increased to 240% during the last decade in the Sultanate of Oman due to population growth and industrial expansion. Solar energy can act as an alternate source of energy production to meet the surge in demand for electric power. Also, the government has planned to derive 30% of the electricity from renewables by 2030. Moreover, agreements have been made to reduce greenhouse gas (GHG) emissions by decreasing 7% by 2030. The main objective of this paper is to design a grid-connected PV solar system based on the real-time data collected from t

Abstract:

Purpose Obviously, the development of a robust optimization framework is the main step in energy and climate policy. In other words, the challenge of energy policy assessment requires the application of approaches which recognize the complexity of energy systems in relation to technological, social, economic and environmental aspects. This paper aims to develop a two-sided multi-agent based modelling framework which endogenizes the technological learning mechanism to determine the optimal generation plan. In this framework, the supplier agents try to maximize their income while complying with

Abstract:

Abstract Storage technology and consumption technology can reduce the amount of abandoned wind and sunlight, improve the utilization of new energy, and reduce cost. Firstly, this paper describes the role of P2G (Power to Gas) technology in the field of new energy consumption, then builds the economic cost-optimal day-ahead optimal dispatch model based on a microgrid, examining the ability of P2G devices to consume new energy. Finally, three different scenarios are applied in the example for verification. The calculation example proves that P2G devices have a good effect in the field of scenery

Abstract:

Due to the adaptation of recent pollution mitigation and justification policies there has been a growing trend for electricity generation from various renewable resources. The selection of the optimal renewable energy technology could be measured as a complex problem due to the complication of forthcoming circumstances in any country. Consequently, the proposed similar complex assessment problem can be tackled with the support of Multiple Attribute Decision Making (MADM) methods. The current research study investigates a technology selection problem by proposing a hybrid MADM approach based on

Abstract:

New energy is fast-growing in China. However, new energy cannot develop without financial instruments that are different from the traditional financing of existing energy projects. Therefore, this paper, theoretically, studies how to find the optimal financing vehicles, and qualitatively analyzes the possible financial operations for the new energy. To this end, we, specifically, propose the risks of financing investment in new energy, the advantages of financing it, and how we could balance the risks and advantages of financing behaviors in new energy.

Abstract:

Aiming to reduce the weight of components, thus allowing a profit in terms of energy saving, automotive industry as well as aircraft industry extensively uses aluminum alloys. The most widely used joining technology in aircraft industry is riveting, while welding seems to be used in the car industry in the case of aluminum alloys. However, welding technology is characterized by many defects, such as gas porosity; oxide inclusions; solidification cracking (hot tearing); and reduced strength in both the weld and the heat affected zones which could limit its development. Many techniques are used

Abstract:

To advance carbon neutrality policies, many countries are increasingly integrating Renewable Energy Sources (RESs) into their energy mix. However, for harnessing natural energy in power generation, RESs present challenges in output control, potentially leading to power imbalances. Such imbalances, when coupled with an excessive reliance on unpredictable RES, may necessitate the curtailment of grid-integrated renewable generation, halting production despite available capacity. This paper proposes strategies to mitigate the economic and operational efficiency impacts of increased RESs on the pow

In the current context of huge global energy consumption and harsh climatic conditions, the energy efficiency and sustainability of buildings have received much attention. The nearly zero-energy building (nZEB) is a feasible solution for solving the energy crisis in the building sector in recent years, and it is important to study the adaptability of its technology system. However, existing studies have not addressed well the issue of the impact of complex and diverse climates on the technology systems of nZEBs.

Abstract:

The increasing energy crisis and environmental problems promote the development of distributed energy systems (DESs) that utilize combined heat and power technology, renewable energy technology, and waste heat recovery technology to meet various load requirements. Although there is existing work and research on a variety of DESs, most previous studies tend to focus on energy production with little consideration of a distributed energy network and its energy loss, which results in large errors in energy-efficiency calculations and performance analyses. In this paper, a new DES model is proposed
