【摘要】：新能源场站普遍存在点多面广、单场容量相对较小的特点,因此部分电网虽按同一控制区运行,但选择将新能源场站控制权下放,形成风电资源两级控制现状。为协调常规能源与风电运行,最大程度消纳风电,通过将下级调度风电整体等效为上级调度的自动发电控制(AGC)虚拟机组,提出同一控制区两级调度风电实时协调控制架构,并投入实际运行。上级调度根据电网当前运行状态、负荷超短期预测和风电实际出力及预测,每5min滚动计算得到电网内各个下级调度的风电发电指标,经余缺调剂后,下发给下级调度风电AGC执行。在大风季、供暖期的运行结果表明,采用所述的两级调度实时协调控制方案后,达到了京津唐地区风电增发的效果。
[Abstract]:The new energy station has the characteristics of wide spot and relatively small single field capacity. Therefore, although some power grid is running in the same control area, the control power of the new energy field station is put down to form the two level control status of wind power resources. An automatic power generation control (AGC) virtual generating unit, which has been dispatches by the superior, is proposed, and the two level dispatching wind power real-time coordination control architecture in the same control area is put forward and put into practice. The superior scheduling is based on the current running state of the power grid, the overload of the load and the actual power and prediction of wind power, and the wind power of each scheduling in the power grid is calculated by every 5min rolling calculation. In the wind season, the running result of the heating period shows that the effect of wind power increase in Beijing, Tianjin and Tang area is achieved after the two stage scheduling real-time coordination control scheme is adopted in the windy season.
