Meeting environmental constraints represents a particularly important condition that energy systems are currently facing, especially with the emphasis on mitigating global warming process. Reducing carbon dioxide emissions is therefore one of the main practices that can be used to achieve the objectives set by energy policies in this regard. This paper aims to assess the decrease of these emissions...
This paper analyzes the green potential of a newly developed urban community, i.e., Nordhavn, in Copenhagen, Denmark from a planning perspective, wherein the energy sector of power, heat and transportation will be developed as an integrated energy system solution. Based on an hour-by-hour analysis wherein the generation and demand in each energy sector are balanced, the analysis explains how different...
Stable power plant operation is the only way to ensure daily production of electricity. However, this operation is highly prone to breakdowns that often lead to a power outage known as a power failure. Another disadvantage of this operation is its significant contribution to environmental pollution in its consumption of fossil fuels. To avoid these problems, this study investigates ways to integrate...
With the growing concern about sustainable development and sustainable energy, there exists increasing pressure on energy-efficiency technologies to reduce energy use and greenhouse gas emissions. This paper discusses and analyzes on real regional data the potential of biomass in energy-efficiency issues, how to determine the volume of changes of heating from coal or natural gas to wood and the effects...
Reliance on round wood for heating and cooking has increased the percentage of deforestation to 0.7% per annum especially within sub-Saharan region where communities live off the electricity supply grid. The majority of these communities rely on agriculture and forestry activities for sustenance. Therefore, large amounts of agricultural and forestry residues are produced annually although they are...
This paper presents a study on the design methodology of domestic mechanical anaerobic digesters. The energy crisis in Africa and especially in Southern Africa has raised concerns over the effects of depleting fossil fuel reserves. With recent improvement in biogas technology; development, implementation and commercialization of prefabricated plants for biogas production has led to the recognition...
This paper contains the study about the potential of India in terms of renewable energy sources. India has very large potential of renewable energy sources, with one of the biggest programs for the development of available renewable energy sources. Ministry of New and Renewable Energy Sources (MNRE) is the special ministry for renewable energy development in India, and it is the only country worldwide...
Motivated by the new feed-in tariffs for electrical power projects generated from renewable energy resources, the present study is investigating the potential of on-grid hybrid solar/wind/Biomass power generation in Egypt. The arrangement is modeled and examined through the environmental and economic prospects. The optimization, sizing and economic assessment of the introduced systems were accomplished...
The article presents a model of controlling the flow of energy in agricultural biogas plant. Control model was made on the basis of a shared project biogas power plant. Biogas plant control algorithm modeled using SCADA software and an analysis of cost performance and life of the investment have been presented.
This paper presents the biomass gasification as a suitable technology for rural electrification plants in developing countries. The main problems of the gasification plants and the perspectives of this technology were analyzed. It concludes that currently the gasification is a viable alternative for electricity generation in rural conditions although more research is needed to evaluate the long-term...
The energy internet paradigm provides a platform to integrate and utilize multiple energy resources through advanced hardware interfaces, communication infrastructure and operational intelligence. In this paper, a robust energy management framework is proposed for dispatching multiple renewable energy resources including solar power, wind power and biomass generation, and flexible loads. In the framework,...
Microgrids that use distributed renewable energy sources have received great attention in recent years. In this study the microgrid incorporates a photovoltaic and a biomass generator, uses lead-acid batteries as storage in order to supply the loads of a vegetable greenhouse. The main objective of this paper is to investigate the performance of a three phase induction generator that supplies a single...
The transition towards a decarbonized power system requires the integration of large shares of variable renewable energy sources. Their intermittent nature challenges the short-term ability of the power system to maintain the system balance, and its long-term ability to meet the peak demand. This results in an increased need for operational flexibility. Simultaneously, the availability of conventional...
Hybrid power systems are a combination of electric power generation technologies configured to meet specific customer needs such as reliable electric power, low cost, or portable power. If the power generation uses renewable sources such as wind, geothermal, solar, biomass, and waste, then the result is rightly considered a renewable system-of-systems. This is because each of the power systems can...
Ilakan community in South-West Nigeria, with a population of about 300 dwellers, has had no access to any form of electricity since its existence. A large percentage of the population is very active and engages in productive activities, predominantly farming. This paper aims at providing affordable, clean, off-grid electricity to the community by designing a decentralized energy hub where residents...
Production of electricity from Bryophyllum pinnatum leaf is very cheap and the cells are easy to maintain and operate for any people as this leaf contains some organic acids. The main raw materials to produce electricity in this process are the zinc and copper plates and the juice of Bryophyllum pinnatum leaf. This plant can be grown anywhere. As there is plenty of free spaces in off-grid areas, the...
The increase of the energy needs accompanied with a predictable exhaustion of the fossil resources and the environmental problems engendered by their consumption, clearly reveal that the current energy model is not sustainable. We must therefore engage a transition towards a more sustainable model. The solution is not unique but the use of renewable energy seems to have many advantages, due to their...
Many biomass solid wastes are being considered to be potential sources of renewable energy. In this paper, mahogany seeds, sawdust, rice husk and coconut shell are considerable feedstock which are used for pyrolysis system to produce non-conventional fuel. The products obtained while using these feedstock are pyrolysis oil, solid char and gas. The property of the oils produced from different biomass...
This paper is mainly addressing the design and analysis of a hybrid Solar and Biomass System for rural electrification in a remote area in Bangladesh by Decentralized Distributed Generation & Rural Power Distribution Management. Energy is crucial input in the process of economic, social and industrial development. Energy plays a vital role in our daily life. But the conventional source of energy...
World is heading towards the crisis of fossil fuel. Energy crisis is more acute in Bangladesh, as there is no petro-fuel source but only natural gas. It has among the lowest per capita energy (240 kg oil equivalents) consumption in the world and is severely dependent on additional environmentally friendly renewable energy resources in the future. To cope up with present situation and to reduce dependency...
