Abstract: | Among the many forms of renewable energy generation, wind power is th e most mature. However, the method used to assess the economic value of large gr id-connected wind farms still needs further study. At present the traditional m e thod of project economic assessment as widely used in China isolates the wind fa rm 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 t rue 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 the oretical basis to establish an economic evaluation model for large wind farms including the characteristics of other conventional forms of power generation li ke 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 lar gest wind farm, Dabancheng Wind Farm in Xinjiang. |
