Abstract: - This paper presents an overview of the development in wind energy technology. Growth in wind technology and components of wind energy conversion systems are provided. Ratings, and system size are included for various applications in addition to power electronic converters and advantages of use. Attention is paid to offshore wind farms and their transmission systems. High wind power penetration in utility is discussed and role of wind forecasting is considered. The paper covers the required research and technical development in wind energy.
Key-Words: - Wind Energy, Technology, Development, Power Electronics Converters during disturbance in addition to reactive power compensation. Recently, multi-megawatt size of WTs can reach 4-5 MW generating capacity and are adequate for offshore wind farms in USA & Europe. Environmental condition on the sea is taken into consideration for the wind farm and substations. Investigations also cover feasibility of floating wind farms in deep water, using artificial intelligence in wind forecasting, low speed machines (direct driven generators) and smart control systems.
1 Introduction Wind energy is the most promising renewable energy source due to the progress in conversion technologies to produce electricity. Such progress in wind technologies leads to the reduction in the cost of KWh to be more competitive with conventional sources for both capital and generated electricity costs. Therefore, wind is expected to supply about 12% of the world electricity demand by 2020. Electricity production from wind energy covers several applications from micro-turbines (
