Isolated and small electricity consumption locations such as Islands are not providing enough foundation for grid extensions to deliver electricity to the localities. Therefore, most of the Islands are using stand-alone generators to deliver power to the consumers. However, this not only increases the cost of energy generation but also increases the threat of global warming and makes them susceptible...
The 21st century is named as green technology century and most of reasons for global warming such as air pollution, greenhouse gas and extra usage of oil and gas sources are being discussed to be replaced by a green idea, hence the United Nation, governments, universities around the world, and environmental activists alongside with scientists have already started researches and investigations over...
The amount of the conventional energy sources is decreasing day by day on earth. To avoid the energy crisis, the incorporation of the use of renewable energy sources is highly required. For decentralized or remote areas, where grid connection is almost not possible, renewable energy generation system coupled with diesel engines can be a reliable and optimized source of energy. In this study, a remote...
<?Pub Dtl?>The paper investigates renewable energy alternatives to reduce diesel fuel dependency on electricity generation in Ontario's remote northern communities; currently, these communities use diesel fuel as the sole energy source to produce electricity. The current operation is complex, involving several stakeholders, high operating costs, and a considerable CO footprint. Several...
Hydropower can provide inexpensive, flexible fill-in power to compensate for intermittent renewable generation. We model the decision of a hydroelectric generator to shift power capacity away from the day-ahead energy market into a "wind-following" service that smoothes the intermittent production of wind turbines. Seasonal wind patterns produce conflicts with "ecosystem services"...
The world is anticipating the leaders and planners of future energy market to come up with some tangible and sustainable solution, to deal with the dependence and reliance of humankind over hydrocarbon resources for their energy requirements, not only to cope with the exponentially growing demand but also to the hazards and risks to the mother nature due to carbon emission. With strong commitment...
This paper aims at production electricity by using the concept of the rotation of wind turbines due to the wind caused by a moving vehicle. This will help to cut down the usage of non renewable sources which is on the verge of extinction.
For the electrical supply of solitary remotely located objects - such as telecommunication relay stations, alpine huts, or farms and small settlements in developing countries -autonomously operated micro-grids are established, favorably based on renewable energy sources. The appropriate configuration of such micro-grids - in particular with respect to eligible energy sources and storages - is a demanding...
Wind generators in the British electricity market have historically been spilling a significant part of their output in the system, without trading them in the open market. The effect is that the system operator has to operate in an environment where self-balance is no longer the norm, creating ever growing challenges for decisions in the real time operation of the market, especially moving forwards...
Electrical supply of remotely located objects — such as telecommunication relay stations, alpine huts, or farms and small settlements in developing countries — requires autonomously operated micro-grids, favorably based on renewable energy sources. Proper design as well as reasonable control of such small scale power systems are posing a challenge which was taken up by the development of a comprehensive...
With the Smart Grid trend setting in, demand response plays an important role for both the consumer and the utility. Demand Response is the consumers' response to the changes in the price of electricity. Dynamic pricing schemes including Critical Peak Pricing (CPP) and Time of Use (TOU) provide options for consumers to influence their electricity bill. Such pricing options may also make owning a small...
Climate change and security of supply have made it imperative for Europe to look at renewable sources of energy. Among the available sources, wind has emerged as the preferred option and this is evident from the fact that in 2008, wind formed the highest proportion of total capacity addition in Europe. Improvement in turbine efficiency, which in turn reduced the per unit generation cost of wind turbine...
In recent years, penetration of wind generated electricity into power grids has been increasing significantly. During the last few decades, wind energy has doubled in capacity every three years. Because of the intermittent characteristics of wind power, it is usually difficult to determine an acceptable penetration level to maintain specific reliability requirements. The need for better capacity credit...
Electricity markets are currently evolving to accommodate large scale penetration of wind generation. In this research, potential changes to the classification and role of wind generators in the Single Electricity Market (SEM), the market for Northern Ireland and the Republic of Ireland, are examined. The effect of wind generators opting to become price-making and the potential for wind generators...
The use of energy storage integrated with wind power is commonly considered in a system for increased operational flexibility. In past years, a fast growth in development of wind generation has been experienced in power system, due to many factors including environment and depletion of fossil fuel resources. With increasing installed wind capacity, the intermittency issues must be addressed. One way...
Rapid economic growth in China requires large amount of electricity supply. When centralized generation (CG) can not provide sufficient electricity supply, distributed generation (DG) draws people's attention. In this paper, the development status and applicability of DGs in China is discussed in detail, and three typical DG utilizations are introduced. Finally, the development of wind generation...
This paper presents a formulation of security-constrained unit commitment (SCUC) problem with emphasizing on wind power and compressed air energy storage (CAES). In past years, a fast growth in development of wind generation has been experienced in power system, due to many factors including environment and depletion of other resources. With increasing installed wind capacity the intermittency issues...
This paper presents an innovative wind/PV/diesel hybrid system implemented in three remote islands in the Republic of Maldives. The design methodology and preliminary results are presented. It is expected that the newly developed and installed system will provide very good opportunities to showcase high penetration of renewable energies using state of the art wind turbines, photovoltaic modules and...
Electric power generation is the second-largest category of greenhouse gas emissions (GHG) in California, next to transportation. Californiapsilas legislature and energy regulators have adopted aggressive controls on the GHG emissions from electricity production, as well as aggressive targets for renewable energy due to heavy reliance on natural gas as a fuel for electric generation. These regulations...
The renewable energy sources are going to become the long-term solution for future energy. Adequate infrastructure development is of crucial importance to harness power from them.
