随着风电的快速发展,大规模风电接入给省级电网调度运行带来一系列问题。首先,对风电出力的重要特性指标及其对电网运行的具体影响进行阐述分析;其次,为了更好地量化计算风电出力不同时序特性对电网的影响,建立一套从多角度反映风电时序特性对电网调度运行影响的特征指标,然后根据多个风电场群的真实出力数据,分别从不同时空尺度分析风电出力时间序列的分布特性、波动性及相关性;最后,基于某省级电网数据及其并网风电出力数据,研究分析风电时序特性对电网调频、调峰等影响,为省级电网风电优化调度提供参考。
With the rapid development of wind power
the large-scale wind power integration brings a new range of issues in dispatching operation of provincial power grid. Firstly
the important characteristics of wind power output and its specific impact on power grid operation were analyzed. Secondly
in order to gain a better grasp of the influence caused by wind power combined to the grid
the impact characteristic index was established. Then
according to the actual output data of multiple wind farm groups
the distribution characteristics
volatility and correlation of wind power output time series were analyzed from different time and space scales. Finally
based on a provincial grid data and its integrated wind power output data
the impact of wind power time-sequence characteristic on power grid
such as the frequency regulation
peak load regulation was studied
which can provide the reference for wind power optimal dispatching of power grid.
