Along with the development of wind power in Fuxin, the electric network composition will be bound to incline towards acceptance of wind power. Meanwhile, the accurate estimation of wind power installed capacity will directly affect the development and planning of electric network composition. This paper, based on the actual operating data of the existing wind farms in Fuxin, in analogy to the overall wind resource in this region, estimates the relatively accurate limit value of wind power installed capacity through theoretical calculation and provides theoretical basis for the planning and transformation of the electric network in Fuxin.

Wind is a powerful and renewable source of energy that flows in every corner of the surface of the planet. As the world moves towards renewable and alternate energy sources, the potential of wind energy has been recognized and methods to use it to its maximum potential are being explored. India has been harnessing wind power over the years, but only lately, it has sent an ambitious target of achieving 60 gigawatts (GW) of wind installed capacity by 2022. The government has issued several tenders to invite private players or Independent Power Producers (IPPs) to develop wind energy projects. Many foreign investors and the Private Equity players have shown interest in investing in this growing renewable energy (RE) market in India. However, developing a wind project comes with lot many challenges as compared to any other RE project. These challenges range from land availability to seeking grid connectivity approvals and evacuation of the power. Along with this, the current reverse bidding process for the tariffs, have made the per unit tariffs to cost as low as INR 2.4. Hence, it is important to consider the technical and commercial feasibility of the project to function at these tariffs. This paper studies the current scenario of wind energy in the Indian market and analysis the potential for the development of wind projects. It also analyses the technical and commercial feasibility of the project by assuming a 300 MW project, having INR 2.5 as tariff, using Wind Resource Assessment (WRA) and Financial Model.

<p>Offshore wind energy development and utilization plays an important role in haze governance and fulfilling the reduction commitments in advance. The reserve estimation of offshore wind resource in China is abundant enough to meet the basic needs from the exploitation of wind power. Recently, more and more attention is paid to the accurate estimation of the offshore extreme winds, which impose an important effect on the wind turbine designs and operations. Different from the abundant study of the typhoon extreme winds, because of lack of the effective methods, it shows a significant deficiency in the study of offshore extreme winds over the mid-high latitude, which is also the key area for the exploitation of wind power. Therefore, based on numerical modeling and spectrum analysis, the paper developed a practical, reliable and robust method for 50-years extreme wind estimation that can be applied for other mid-latitude offshore area in China. Taking into account the complex climatic characteristics of China's mid-latitude offshore area affected by high latitude cold winter wind and tropical cyclone, the 50-yr return wind speeds at 100m over Jiangsu offshore area were estimated by this new method. It was shown that (1) affected by the strong cold winter winds, the 50-yr return wind speed in the northern part of Jiangsu offshore area exceeded 40 m/s; (2) the 50-yr return wind speeds of 40 m/s, or even 44m/s near Xiangshui and Rudong was related to the limited typhoon activities; and (3) the 50-yr return wind speeds over the central Jiangsu offshore area were generally lower than 35 m/s. This study may not only provide a scientific basis of the design and operation of offshore engineering, such as offshore wind farms in the future, but also contribute to future understanding of the extreme climate events in China and the development of atmospheric boundary layer theory as well (This abstract has been published in <em>Acta Meteorologica Sinica, </em>2019, 77(5): 938-948. doi:10.11671/qxxb2019.054).</p>

The Impact

In recent years, wind power penetration into the grid has increased rapidly with abundant wind resources in Jiuquan, according to the policy of the Chinese government to “establish a ‘Hexi Wind Power Corridor’ and rebuild another Western ‘Terrestrial Three Gorges Dam’”. By the end of 2010, the total installed capacity of wind power in Jiuquan has reached 5160 MW. The wind farms are connected to 110 kV transmission network or above in Jiuquan, the studies of their impacts on the grid, in particular, the grid operation are becoming serious and urgent. Jiuquan is far away from the load center with a weak grid configuration, therefore issues such as transmission line overloading, local grid voltage fluctuation, and transient stability limitation are looming with large scale wind power integration. The power system dispatch and operation are influenced by the intermittent nature of the wind power, which should be regulated by the system reserves. This paper discusses the recent integration of wind power into the grid with a focus on the impact on the Gansu power grid operation. The paper also presents the measures to deal with these issues.

Wind energy is very abundant in Hexi Corridor, and inspired by government policy impetus to build “the Three Gorges on land”, total installed capacity in Hexi grid has increased sharply, and Jiuquan wind power base will become the biggest connecting wind farms in the world. However, Hexi grid has a weak grid configuration, therefore, issues such as insufficient reactive power, transient stability change, and local grid voltage level decreasing could emerge with large scale wind power integration. It’s very necessary to input SVC to implement dynamic reactive power compensation, which is helpful for improving voltage stability. This paper introduces the basic principle of SVC and SVC’s working state in three situation. Then models and simulates the effect of SVC on Gansu Hexi grid static load margin by BPA. At last, proves SVC can improve static load margin.

Wind Resource

The offshore wind farms have many advantages over the onshore ones: they are not affected by the terrain, ground vegetation, buildings and other landscape features, so they have stronger and steadier wind, higher wind power density, smaller turbulence intensity and other advantages. Therefore, offshore wind power becomes the developing trends of wind power industry nowadays. However, its development faces the challenge of how to assess offshore wind resources accurately. It is difficult to get accurate, long-term, large-scale measured data on sea, and the nearshore observations cannot be substitute for the offshore wind conditions directly. This paper applies the NCEP CFSR reanalysis data (combines with the WMO marine observation data) to research the offshore wind resource assessment of China. We find that CFSR reanalysis data is consistent with the observation data, and it can provide a reference for China offshore wind resource assessment. The result of China offshore wind resource distribution is obtained finally.

Wind turbine selection and optimal hub height positioning are crucial elements of wind power projects. However, in higher class wind speeds especially, over-exposure of wind turbines can lead to a reduction in power generation capacity. In this study, wind measurements from a met mast were validated according to specifications issued by IRENA and NREL. As a first step, it is shown that commercial WTGs from a database may be matched to the wind class and turbulence intensity. Secondly, a wind turbine selection algorithm, based on maximisation of capacity factor, was implemented across the range of WTGs. The selected WTGs were further exposed to an iterative algorithm using pointwise air density and wind shear coefficients. It is shown that a unique maximum capacity factor, and hence wind power generation, exists for a wind turbine, premised on its eventual over-exposure to the wind resource above a certain hub height.
