为提高自动发电控制(automatic generation control,AGC)智能化水平及实时调节效果,依托新型 D5000系统在线数据平台,提出基于全网分布负荷同步超短期预测的 AGC 主动协调安全约束经济调度模型。通过全网站点负荷差频滚动灰色预测,一方面预判 AGC 可调以提示人工干预,另一方面以机组发电尽量接近最优日前计划及尽量降低调节代价为目标,预分配各机组出力,从而实现高度智能化的 AGC 主动协调调度功能。在华中某省级电网调度模拟系统进行仿真计算,结果表明该模型在保障电网安全、优化运行指标、提高发电调度自动化程度等方面具有明显的优势。

In order to improve intelligence level and real-time dispatch effect of automatic generation control (AGC),a secu-rity constrained economic dispatch(SCED)model for AGC active coordination based on synchronous ultra-short term predic-tion on distributed load of the whole grid was proposed depending on online data platform of new typed D5000 system.By means of rolling grey prediction on load different frequencies of the whole grid stations,anticipation of AGC adjustability was carried out for reminding artificial intervention on one hand,and on the other hand,with the target of power genera-tion of the unit close to the optimal day-ahead plan and reduction of adjustment price to the greatest extent,output of vari-ous units was pre-distributed for realizing highly intelligent AGC active coordinated dispatching function.Simulating calcula-tion was conducted on dispatching simulation system of some provincial power gird in central China area and the result indi-cated that this model was of obvious advantages in ensuring power grid security,optimizing operational index and improving automation degree of power generation dispatching.
