However, the method used to assess the economic value of large grid connected wind farms still needs further study. At present the traditional method of project economic assessment as widely used in China isolates the wind farm from the whole power system and ignores the influence of reliability on the cost of wind generation; therefore, the evaluation results can not reflect the true economic value of wind power generation. After reviewing the many assessment methods used at home and abroad, this paper uses the Avoided Cost Method as theoretical basis to establish an economic evaluation model for large wind farms including the characteristics of other conventional forms of power generation like thermal power as well as the system load. The generating reliability is also combined into the economic evaluation. The model is used to evaluate China's largest wind farm, Dabancheng Wind Farm in Xinjiang.展开更多
