“…For example, Jiangsu province is one of the seven large-scale wind farms, which has total wind generation capacity of 10GW to be installed by the end of 2020. Shandong, Shanghai and Guangdong also have significant offshore wind power potentials [45]. The locations of these wind farms are considered superior to the inland wind farms, since they are nearer to the demand centres.…”

“…For example, the Eighth Five-Year Plan, Ninth Five-Year Plan and Tenth Five Year Plan 1 , power grid investments accounted for 13.7%, 37.3% and 30% of total investment in the electricity sector, respectively. The ratio further increased from 31.1% in 2005 to 45.94% in 2008, the cumulative investment in the power grid is still significantly lower than the investments in power generation [5]. Figure 1 gives a comparison of the ratios of accumulative investments in power grid and power generation in China, the US, Japan, the UK and France since 1978.…”

“…Besides the large-scale grid-connected wind farms, other applications of wind power such as the direct use of wind power could also provide opportunities for future wind power development in China [45]. Non-grid wind power has attracted a lot of attentions in the international power system research [46] [47].…”

After tremendous growth in recent years, China now has 44.7GW of wind-derived power and has surpassed the US (40.18 GW) to be the largest wind turbine owner since the end of 2010. In 2010, around half of the new wind turbines globally were installed in China. Despite the recent growth rates and promises of a bright future, two important issues -the capability of the grid infrastructure and the availability of backup systems -must be critically discussed and tackled in the medium term.The study shows that only a relatively small share of investment goes towards improving and extending the electricity infrastructure which is a precondition for transmitting clean wind energy to the end users. In addition, the backup systems are either geographically too remote from the potential wind power sites or currently financially infeasible. Also, the use of coal-fired plants as the backup system is unavoidable because of the coal-dominated electricity mix. Finally, the introduction of wind power to the coal-dominated energy production system is not problem-free. Frequent ramp ups and downs of coal-fired plants lead to lower energy efficiency and higher emissions, which is likely to compensate some of the emission savings from wind power.The current power system is heavily reliant on independently acting but state-owned energy companies optimizing their part of the system, which is partly incompatible with building a robust system supporting renewable energy technologies. Hence, strategic, top-down co-ordination and incentives to improve the overall electricity infrastructure is recommended.

“…Finally, according to the intergrability and resonance of Hamilton system, a theory based on Hamilton system with stochastic excitation is presented and developed, which is used to study mechanical system with stochastic excitation. Xu et al [3] discussed the stochastic stability and bifurcation of multiwalled carbon nanotubes-absorbing hydrogen atoms subjected to thermal perturbation. They studied the dynamic behavior by useing the quasi-nonintegrable Hamiltonian system theory and the stochastic parametric excitation is regarded as Gauss white noise.…”

Abstract. In this paper, a high speed rotor-bearing system with stochastic excitation is considered, and study the stability and Hopf bifurcation of the system by using quasi-nonintegrable Hamiltonian system theory. Then, the conditions of local and global stability of system are obtained by largest Lyapunov exponent and boundary category. Finally, the solution of FPK equation can be got, which is stationary probability density function and jointly stationary probability density function, and then, by simulating its graph to illustrate the results.

-A reliability model of wind farm located in mountainous land with complex terrain, which considers the cable and wind turbine (WT) failures, is proposed in this paper. Simple wake effect has been developed to be applied to the wind farm in mountainous land. The component failures in the wind farm like the cable and WT failures which contribute to the wind farm power output (WFPO) and reliability is investigated. Combing the wind speed distribution and the characteristic of wind turbine power output (WTPO), Monte Carlo simulation (MCS) is used to obtain the WFPO. Based on clustering algorithm the multi-state model of a wind farm is proposed. The accuracy of the model is analyzed and then applied to IEEE-RTS 79 for adequacy assessment.
