This project addresses three major research problems currently treating our globe. These problems are as follows: the pending energy crisis, the environmental degradation due to an ever increasing growth of waste and the environmental degradation due to the continuous generation of greenhouse gas emissions. In light of these problems, efforts are geared towards the development of a `one-stop' solution. A preliminary survey of available technical data indicates that the three problems could be solved through the use of an efficient `plasma combustion' technology. The usage of this plasma technology can simultaneously disintegrate waste while electrical power is generated and greenhouse gas emissions are eliminated. An innovative aspect of this work is the development of a closed-loop renewable power generation system that can potentially be integrated into local communities. A technical and economic analysis of the proposed system is presented in this paper.

This paper explores the issue of sustainable energy from a multi-flux perspective, and has shown clearly that some of the choices being vigorously pursued today, such as bio-fuels, may have significant limits on scalability. While a Bio-Fueled World does not seem to be sustainable, an Inorganically Fueled World, seems to have the potential to be able to scale to meet global needs, without in any way constraining global growth for the foreseeable future.

Increased bulk power transactions in competitive energy markets together with large scale integration of renewable energy sources are posing challenges to high-voltage transmission systems. Environmental constraints and energy efficiency requirements also have significant effects on future transmission infrastructure development. This paper reviews the recent development in HVDC technologies and discusses the needs of the hybrid AC/DC grid structure for future power systems with focus on VSC-HVDC applications in meshed AC grid. It has also been recognized that hybrid AC/DC transmission system together with the wide area measurement system (WAMS) could effectively manage the overall power grid operation security and efficiency under uncertain supply and demand conditions.

This paper presents a survey about the perception of achievable automobile fuel economies versus EPA ratings. The survey follows up of a driving experiment in which the fuel consumed was 30% lower than the rated consumption for the same distance. On one hand, the results of the survey suggest that for most people, the perception of the possible fuel economy of a particular car seems to be biased by its advertised fuel economy and present standards. On the other hand, the driving experiment confirms that fuel consumption is affected by the driving style of motorists. As a result, this paper constitutes a call to all drivers to be more optimistic about and take some responsibility for the fuel efficiency of their automobiles. Fuel economies that exceed the EPA ratings are easily obtained with a few driving adjustments. In the present energy and environment turmoil, such adjustments result in immediate and significant savings in terms of fuel, carbon footprint, and environmental impacts.

Power Electronics will play a key role in this paradigm shift to more renewable electrical energy and higher energy efficiency in multiple applications including transportation. In electrical energy generation a major shift to renewables as sources of future electrical energy will happen. The political institutions world-wide have the responsibility to create the boundary conditions to accelerate this needed change. Renewables (Wind, Solar, ..) are important future contributors and solar power (photovoltaic or thermal) needs to be taken serious. In regards of energy efficiency we need to focus on efficient bulk power generation including the mandatory use of waste heat for district heating or process industries. This all will ask for a substantial expansion and modernization of the electrical distribution and transmission system with more MVDC and HVDC systems. In industrial processes efficiency improvements can be achieved with a major focus on pump and fan applications. Another 30% of inefficient pump and fan applications need to be converted to variable speed drives to get an average of 40% energy saving in these applications. In regards of transportation up to 30-50% fuel/energy consumption reduction can be achieved with the DC-link based power system to enable efficient hybrid and in the longer term pure electrical solutions in transportation.

Zhenhua Jiang, X. Yu
This paper presents a microgrid paradigm with both DC and AC links, which may provide an effective way to integrate a heterogeneous set of small-size distributed energy resources into the existing electric power infrastructure. The collection of aggregated energy resource units at each level represents those distributed resources to the upper level as a single self-regulated entity (as a DC or AC, generator or load). At the top level, the collection of all distributed energy resources in the microgrid appears to the utility grid as indistinguishable from many other currently legitimate customer sites. Maintaining this profile relies on the flexibility of advanced power electronics that control the interfaces among distributed energy units, DC links, AC links, and the surrounding power system. This paper also discusses some major issues pertinent to behavioral functions and technical requirements of the power electronics interfaces and controls. A decoupled control framework is developed for the hybrid microgrid and the performances are evaluated.

In this paper, an overview of the, for a converter design most important, fuel cell characteristics is given. Different DC-DC converter topologies are presented. Their qualification for a low-input voltage, high-input current application is discussed. A comparison of the converters is given with regard to the power range they are appropriate for. The limiting factors for the transferable power are pointed out. For two topologies, a current-fed converter and a two-stage converter, experimental results are shown.

The smart grid is entering the era of practical pilot projects and readiness to scale. This has been the result of a movement in technology, regulation, and a learning process for all involved. This paper discusses several areas of experience with the "intelligent utility network", IBM"s nomenclature for its smart grid concept. Topics addressed are the grid wise demonstration with the Department of Energy's Pacific Northwest Lab and other research work related to the IUN, projects in progress with customers to create the foundations of a smart grid, technology and architecture, and aspects for the enablement of alternative and distributed energy and plug-in hybrid electric vehicles. From a business perspective, the IBM IUN utility coalition and the IUN maturity model will be discussed.

Demand response (DR) provides means for utilities to reduce the power consumption and save energy. Plus, it maximizes utilizing the current capacity of the distribution system infrastructure, reducing or eliminating the need for building new lines and expanding the system. A typical DR program requires two parties to cooperate: the utility and the customers. In this paper a novel intelligent demand response module is designed and proposed to be implemented at the customer side. The primary target of this design is large industrial sized customers that often have several manufacturing/production lines consisting of mostly large electric motors. The proposed DR module design is based on the expert systems theory. Different modules are designed that take the market rates as well as the local load management policy of the customer into account in order to make a decision for reducing the load. The validity of the proposed algorithm is tested on the IEEE 34-bus distribution test feeder in the real-time RT-Lab environment.
