Economic modeling of distributed generation (DG) systems has become an important area of research with the modern push towards greener and more sustainable electricity generation practices as any proposal without a solid business case is bound to flounder with the state of the global economy. This paper assessed the state-of-the-art in DG economic modeling and based on this developed a model to determine...
Fuel cells (FCs) are important for building combined energy systems due to their high efficiency. Molten Carbonate FCs (MCFC) and Solid Oxide FCs (SOFC) have been identified as best candidates for FC Combined Cycles (FCCC). This paper presents a procedure for evaluating the trends in emission levels and economics of FCCC based energy conversion systems, utilising biomass and/or fossil fuels. This...
As a result of the depletion of easily exploitable and therefore cheap coal mines, new power plants have been built or are in construction for burning low value, high moisture content lignite in several countries.
As one of the top five most seriously polluted cities by acid rain in the southwest of China, Nanchong was selected as one of 18 pilot cities of China for Clear Energy Action (CEA) by the United Nations Development Program (UNDP) and China National Science and Technology Ministry (NSTM) from 2001-2005. We analyze and discuss the economic, social, and environmental significance and impacts of the substitution...
We demonstrate an alternative approach for the hedging of flexible energy conversion networks appropriate for use in campus scale and municipal scale utilities with complex energy requirements, fuel sources, and operational flexibility. This new approach utilizes empirical modeling of price models for alternative commodity fuels coupled with a previously reported class of bilinear models for estimating...
The New England power system is highly dependent on natural gas-fired generating units. As a result, the price of natural gas drives the price of electrical energy and the amount of environmental emissions. The system benefits when the price of natural gas is low. However, there is a need to mitigate the risks of high prices of natural gas through the diversification of fuel supply, especially as...
This paper summarizes a modeling framework that characterizes the key underlying technologies and processes that contribute to the supply chain energy use and greenhouse gas (GHG) emissions of a variety of goods and services purchased by U.S. consumers. The framework couples an input-output supply chain modeling approach with ldquobottom-uprdquo fuel end use models for individual IO sectors. This...
The Gulf Cooperation Council (GCC) is nearing the completion of a high voltage transmission system designed to integrate the power systems of Saudi Arabia, Kuwait, Bahrain, Qatar, the United Arab Emirates and Oman. The objective of this paper is to review the underlying economics of electric supply within the GCC before interconnection, to evaluate the plans for further developments in generation...
The depletion of gas with its use is a great concern of Bangladesh. Electricity sector consumes 47% of total annual use of gas. Because of the peculiar input energy requirement characteristic of thermal units with their output the generating units are operated such that the total input energy requirement is minimum in a power system. As load management through load shedding, is a common phenomenon...
Energy is the bedrock of our daily lives and industry. Now is the time that industry, government and academia must join together and examine highly independent, fully environmentally considerate and rational energy systems. In this presentation, recent Japanese policy will be introduced focusing on new national energy strategy. Looking at future technology trends, it is probable that, in the case...
