Aerofoil Aerodynamics of Wind Energy Devices

Wave and tidal energy provide a renewable source of electricity. However, their inherent fluctuations may have a negative impact on the power quality of a local electrical network. Grid operators assess this impact through the use of dynamic models of the generation units, which are inserted into the overall power system model. Providing these models is a compulsory step for any power generator to procure a grid connection above a specified power capacity. Significant issues were encountered in the wind energy industry regarding the dynamic modelling of devices, among which were model numerical instability, poor dynamic model quality and model incompatibility. Considering the large diversity of device types in the emerging ocean energy industry, these problems are considered as a major barrier to the larger scale grid-integration of marine energy converters. Dynamic models must clearly demonstrate the compliance of the actual power generation device and array of devices to the grid code requirements for grid-connection to be allowed. A further barrier to grid connection of ocean energy devices is that existing grid codes — mainly written in the context of wind energy — may be irrelevant or inadequate for ocean energy devices. This paper presents an overview of these issues, and details a radically different approach to the dynamic modelling of ocean energy devices that will assist in overcoming the issues previously encountered in the development of wind turbine models. It also highlights the gaps and inadequacy regarding grid code requirements for ocean energy devices, and provides some recommendations for a new ocean energy grid code.

Abstract The publication presents the results of analysis of possible local benefits factored in utility scale wind energy for a remote location. Electricity is one of the most vital problems on the Earth, thus utility scale wind and solar energy devices are boosting economic development. Energy demand is constantly increasing, despite efforts to ensure the energy efficiency of devices. People are looking for more energy and electricity to consume. Although wind energy is still being researched and improved, modern generation of wind energy is becoming more and more effective and desirable. This publication presents an effective solution to this issue. It deals with the generation of green environment friendly electricity from wind turbine. The genuine idea is to provide energy for remote location using onshore wind turbines. An analysis of the demand for energy at a remote location and electricity consumption was made to provide preliminary calculations of the wind farm. The number of required turbines is determined taking into account all related factors. A specific wind turbine has been selected and proposed to provide the necessary location with the necessary amount of energy. The analysis carried out showed that the produced energy is environment friendly since there is no carbon dioxide emission.

The Impact ◽

Major Reduction

The research and the prototype projects in the GCC countries were in place since 1970's which first was started in Kuwait, followed by Saudi Arabia in the 1980's, United Arab Emirates in the 1990's, Bahrain, Oman and Qatar in 21 centuries. Now all GCC countries had conducted, relatively, large project in solar and wind energy, especially Kuwait (currently about 70 MW among a plan of 2000 MW by 2030), UAE (currently about 300 MW among a plan of 2500 MW by 2030) and Saudi Arabia (with an ambitious renewable energy target of 3450 MW by 2020 with a further 6000 GW envisioned by 2023 and to 200 000 MW by 2030). Such an acceleration in the use of solar and wind energy would have an impact. Major impacts are: (1) Major reduction in the solar electricity prices in the region; (2) More investors in renewable energy business; (3) Rise of innovative design of houses to utilize its structure in installation and integration of renewable energy devices; (4) Rise of many service and maintenance of solar technology companies; (5) Establishment of new academic programs and courses in solar and other renewable energy technologies in the higher education institute and technical organizations; (6) More concern and studies on disturbances to the main grid due to solar connection; (7) Major reduction in carbon footprint per capita in GCC countries; (8) Use of more efficient and low consumption household and industrial devices; (9) Boost in battery industry for solar electricity storage.
