Abstract:

Sweden is working on increasing the share of wind energy, but it comes along with many challenges,one of those challenges is the uncertainty of the wind power; CHP could be an option for betterutilizing of wind power by adapting the power to heat ratio according to wind energy fluctuation.The potential for utilizing installed wind energy in Sweden using CHP plant has been studied. A CHPplant installed in the South of Sweden was considered as studied case. To match the heat andelectricity demand requested by the region with the output from the CHP plant two scenarios weresimulated. Results show

Abstract:

Clean Development Mechanism (CDM), is a market-based mechanism under the Kyoto Protocol. It allows developed countries to implement emission reduction projects in developing countries, to assist their sustainable development; meanwhile, developed countries gain credits which could be used to meet part of their emission reduction targets under this protocol. There is a wide range of various types of CDM projects, among which, wind power projects account for the largest share. Additionality is a key component for CDM projects’ eligibility and to ensure CDM’s environmental integrity. It means tha

Abstract:

Rapid deployment of terrestrial wind power plants (WPPs) is a function of accurate identification of areas suitable for WPPs. Efficient WPP site prospecting not only decreases installation lead time, but also reduces site selection expenses and provides faster reductions of greenhouse gas emissions. Combining conventional predictor variables, such as wind strength and proximity to transmission lines, with nonconventional socioeconomic and demographic predictor variables, will result in improved identification of suitable counties for WPPs and therefore accelerate the site prospecting phase of

Abstract:

Losses for wake effects in offshore wind farms represent about 10% to 20% of the park annual energy production. Several analytical wake models have been developed and implemented to predict the power deficit of a wake-affected wind turbine. Validating and parameterizing the wake models available in the industry is essential to better predict the wake losses and thus maximize the energy yield of future offshore developments. In this study, a wake model validation is undertaken for the three models available in the commercial software WindSim. Data from Horns Rev wind farm is used to that purpos

<p> Grounding of electrical power systems has and will always be one of the most essential aspects of any electrical system design. Without a proper, well designed and effective efficient grounding network personal safety is at risk, equipment protection cannot be assured, and proper system operation cannot be maintained. Because of these reasons grounding design has become well researched, with long established standards strictly dictating the construction and integration of such ground networks.

Management system for enhancing transfer of knowledge in wind power industry has not received sufficient research attention in recent times. In some cases, the wind power plant owner does not control the management system for operation and maintenance activities. Most of these wind power plants are under contract and rely upon the turbine vendor to perform most of the maintenance works and subsequently share their experience at the initial stage of operation. This research investigates the management system for the operations and maintenance activities of the offshore wind plant in Lillgrund.

Abstract:

Additive manufacturing (AM), also known as 3D-printing is an automated manufacturing process in which the component is built layer upon layer from a predefined 3D computer model. In contrast to conventional manufacturing processes where a vast volume of material is wasted due to machining, AM only uses the material that the component consists of. In addition to material savings, the method has a number of potential benefits. Two of these are (1) a large design freedom which enables the production of complex geometries and (2) a reduced compexity in supply chain as parts can be printed on-deman

Wind generation, with near-zero marginal costs, limited predictability, and a limited ability to provide upward dispatch, displaces price-setting thermal power plants, with higher marginal costs, changing flexibility and reserve requirem

Abstract:

The integration of large amounts of wind power in power systems coupled with the increasing replacement of large conventional synchronous generators by wind power plants (WPPs) presents a considerable impact on power system stability. This is partly because most WPPs, particularly variable speed wind turbine (VSWT) types, are connected to the network via power converters which decouples their output power from the grid frequency, and this results in considerable loss of system inertia. Also, VSWTs are in general operated at the maximum power point tracking, which makes them unable to increase

Abstract:

In attempting to control the power output of a wind farm, it is first necessary to smooth the power fluctuations due to wind turbulence. This is accomplished by spatial smoothing, whereby the high frequency power components of a single wind turbine generator (WTG) is reduced by a factor of N-1/2, where N is the number of WTGs in the farm. For this reason the first part of the thesis is concerned with developing a model of smoothing in a wind farm and justifying it mathematically.<br>After spatial smoothing, the wind farm output still contains low frequency fluctuations. The second part of the

Abstract:

This report describes the iterative process and steps taken to build a tidal power generator which works efficiently while causing no harm to marine life or habitat. A tidal power generator is a device that converts the mechanical energy from the horizontal tides in the ocean (or any flowing water body) into electrical energy. The design was undertaken as an interdisciplinary capstone project for seniors in mechanical and electrical engineering. The results will be used for research purposes in determining the efficiency of the specific design used and the overall feasibility of tidal power ge

Abstract:

The stepwise replacement of conventional power plants by renewable-based ones such as wind power plants could a ect the system behaviour and planning. First, the network stability may be compromised as it becomes less resilient against sudden changes in the loads or generator trips. This is because wind turbines are not synchronized with network frequency but they are usually connected to the grid through fast controllable electronic power converters. And second, due to the stochastic nature of wind, the electrical power generated by wind power plants is neither constant non controllable. This

Abstract:

Climate change is mankind’s biggest challenge and scientists around the globe agree that civilization is pushing towards a breaking point. Renewable energy are alternatives that are capable to remove the need for fossil fuel. Wind power will play a vital role and has the possibility to confront the challenges that face the globe. In order for wind power to reach its full potential constructors need to take into account the distance between each wind power turbine, as it can cause energy loss and generate less electricity into the system. These energy losses decrease the potential of wind power
