Investigation of Wind Energy Density in the Southern and Southwestern Region of Turkey

In this study, wind energy density in the southern and southwestern region of Turkey was investigated by using the Weibull and Rayleigh probability density functions, and the wind atlas analysis and application program (WAsP). Hourly wind speeds and directions collected by the General Directorate of Electrical Power Resources Survey Administration were used. Before the construction of the wind turbine generator in these locations, several fundamental properties of the site such as wind behavior, availability, continuity, and probability should be carried out in order to provide the necessary information to the potential investors about cost and economical aspects of planning the wind energy project. The dominant wind direction, probability distribution, Weibull parameters, mean wind speed and power potential of all stations were determined by the Weibull and Rayleigh models, and the WAsP program. The results obtained with these models were compared with the measured data. Finally, it is found that these regions have a reasonable wind power potential and they are suitable for planting wind energy turbines. However, Belen is the most promising and convenient site for production of electricity from wind power.

Development and Life-Cycle Inventory Analysis of Wind Energy in Taiwan

This study conducted a life-cycle inventory analysis of wind energy utilization in Taiwan. Life-cycle stages of wind turbine manufacturing, foundation construction, as well as operation and disposal of the systems are considered. The functional unit is defined as per kWh of electricity generated by the wind power systems. In 2006, the electricity generated from wind power systems stands at 0.124% of the total electricity supply in Taiwan. Moreover, the estimated potential capacity of wind energy inland falls within the range of 1,656?to?6,624?MW. The resource inputs resulting from the life-cycle inventory analysis are: Steel 1.847?g, aluminum 0.043?g, copper 0.043?g, sands 0.045?g, glass 0.067?g, plastics 0.068?g, petrochemical products 0.024?g, and concrete 6.515?g (per kWh of electricity generated). The intensities of energy consumption and CO2 emission amount to about 0.05?MJ/kWh and 3.6?g/kWh, respectively. Furthermore, the payback time of energy input is estimated as 1.3?months.     

Optimal Expansion Planning for the Deployment of Wind Energy

With the growing concern regarding climate change, the integration of renewable electric technologies into the grid has taken on increased importance over the past decade. In particular, the integration of wind energy is increasing the attention paid to power transmission investment planning, generation adequacy, and secure system operation. This attention calls for the development of new tools that can simultaneously address the economics, transmission, ancillary services, and reserve requirements associated with wind energy. This paper proposes a method for choosing the optimal plan for expanding transmission and generation considering optimal power flow, discrete plant sizes, and the resource variability of wind energy. The method minimizes total cost, i.e., the sum of the construction cost and the operation cost, to fulfill expected load. Due to the nature of transmission expansion planning and the economies of scale associated with conventional power plants, finding the expansion plan is an integer programming problem solved by a branch and bound method. The proposed method is tested by applying it to a nine-bus system.

Cost Analysis and Pricing Policy of Wind Power in China

China has made great achievements in wind power generation. By the end of 2009, the installed capacity of wind power totaled 25.8053?GW, 13.8032?GW of which was added in 2009. Although the industry has developed at an impressive rate, its scale is still comparatively small, not fully matching the country’s economic size and great demand for green power. It is widely believed that the wind power market in China can develop at an even faster rate over the next decade. A stable market for wind power investment relies on both the cost of wind power and an effective pricing policy to motivate growth in the wind industry. This paper presents corresponding analysis of the costs of wind power generation and the current pricing policies implemented in China. The composition of wind power costs is elaborated through comparing it with that of conventional power resources. The localization of wind turbine manufacturing, which aims to decrease the wind generation costs and promote the development of the local wind power industry, is introduced. Two current pricing systems applied in China are examined: the price committed by the wind power concession bidding projects and the price authorized by the provincial governments. An inflation-adapted model is proposed to analyze the risk of concession prices. Finally, the paper concludes with discussions on the potential benefits and the future strategies for the development of wind power in China.
