摘要
提出了利用AGC动态调整并执行日发电计划的策略,给出了实时评估算法作为辅助决策依据。该策略可在机组跟踪日发电计划的同时,根据电网实际负荷与预测偏差,按照节能调度优先级顺序实时调整机组出力,提高了全网AGC调整容量、速率和精度。在河南电网的应用表明,该策略能保证日发电计划的有效执行,为节能调度实施提供了有力的技术手段,并有效提高了电网运行的安全性和省际联络线控制效果。
The strategy of generation scheduling dynamic adjusting and implementing by using AGC is presented, and gives a real-time adjustment algorithm as basis for assistant-decision. The strategy can adjust generation unit＇s real-time power with the energy-saving dispatching priority order according to the grid load forecast bias while generation unit tracking the daily generation scheduling. The whole grid＇s AGC adjustment capacity, speed and preciseness is improved by using this strategy. The application of this strategy in Henan Power Grid shows that it ensure daily generation scheduling implementing effectively, provide a strong technical means for the implementation of energy-saving dispatching, and improve the security of the power grid and the tie-line control effect.
