摘要
风电功率自身的随机性和波动性对电网的运行影响重大。根据我国国内某地区的实测电网数据对基于NASA地球观测数据库的区域风电功率计算分析方法进行验证,并对基于时间和空间的风电功率波动在线评价指标包括风电容量因数和负荷功率的相关系数,负荷峰谷差率,等效负荷峰谷差率,风电场之间年平均功率波动的相关系数进行计算与分析,为调峰能力计算及风电接入能力分析提供科学依据。
The stochastic and volatility of wind power has a great influence on the power grid operation.According to China＇s domestic of the grid data of a certain region,this paper validates regional analysis method to calculate the wind power based on NASA＇s earth observation database and describes the analysis and calculation performed on online evaluation index including wind power capacity of wind power fluctuations factor and correlation coefficient,load power peak valley load rate,equivalent peak valley load rate,correlation coefficient between the annual average wind power fluctuations based on time and space.The paper presented the scientific basis for load capacity calculation and wind capacity analysis.
