摘要
大规模风电接入增加了电网调度运行的变化性与不确定性.为研究风电接入的影响,引入净负荷这一概念,通过对比风电接入电网前后负荷与净负荷的变化特性及预测性能,研究了风电接入对电网频率控制性能以及备用安排的影响.研究结果表明大规模风电接入将引起控制区CPS2指标下降,而电网则必须提高其运行备用,备用增量与风电消纳方式密切相关.
Abstract
Large-scale integration of wind generation increases variability and uncertainty of grid dispatching and operation.To study the impact of wind generation on power grid,the concept of “net load” is employed in this paper.Variability characteristics and forecast error distribution are analyzed for both load and net load.Through comparison of statistical characteristics of load and net load,decreased CPS2 and increased reserve requirement due to integration of large-scale wind generation are observed.Analysis also shows that reserve requirement relates closely to the scale of balancing area.
