中文摘要:

同一区域的多个风电场接入系统时,风电场出力受到风速和风机故障的不确定性和相关性的影响。传统的风电场可靠性建模方法对这些因素的考虑不够全面、对风速和风机故障之间的相关性处理过于简单,为此该文提出一种能同时计入风速和风机故障的不确定性和相关性的风电场建模方法,该方法对风速和风机故障间的相关关系无需作简化处理。基于所建立的风电场模型,采用相关抽样技术模拟风电场出力,克服了传统风电场出力模拟方法所依据的风电场状态模型或风电场出力相关关系不够准确的不足。算例分析验证了风电场建模方法和风电场出力模拟方法的正确性,并表明风速相关性和风机故障对系统可靠性的影响程度与系统输电充裕度、风电场接入地点有关。

英文摘要:

The output power of wind farms is affected by uncertainties and correlations of wind speeds and failure of wind turbine generators(WTG) when wind farms located in the same area are integrated into power systems. However, these uncertainties and correlations are failed to be simultaneously incorporated in the conventional reliability models of wind farms, and the correlation between wind speed and the failure of WTG is simply tackled based on some improper assumption. Therefore, a reliability modeling method of wind farms was proposed which can incorporate the correlation between wind speeds of wind farms and also the correlation between wind speed and WTG failure properly. Furthermore, the simulation of output power of wind farms was implemented based on the reliability models of wind farms by correlation sampling method and it overcomed the drawback of conventional simulation method of output power of wind farms which is based on the inexact multistate models of wind farms or inexact correlation coefficients. Results of case studies not only validate the reliability models of wind farms and the simulation method of output power of wind farms, but also show that the extent of impacts of wind speed correlation and WTG failure on power system reliability is related with the transmission adequacy and the integrated locations of wind farms.
