According to the insufficiency of automatic generation control (AGC) ability of traditional thermal generator, a strategy of control in advance based on ultra-short term load forecasting is presented, with which, thermal generators coordinate with hydroelectric generators with AGC based on area control error(ACE) control, the coordination control of thermal and hydroelectric generators with AGC is realized and AGC ability of thermal generators can be fully utilized.
针对目前常规火电机组自动发电控制(Automatic Generation Control,AGC)性能的不足,设计了基于超短期负荷预测的火电机组AGC超前控制策略,与基于区域控制误差(Area Control Error,ACE)控制的水电机组AGC相配合,实现水火电AGC机组协调控制,达到充分利用火电AGC并调整长期ACE指标的目的。
For reducing the manual burden of AGC adjustment, increasing the acceptability of AGC control and improving the level of power system control automation, the presented Anhui real\|time generation control system automatically modifies the generation scheme of the generation sets according to the accurate super short time load forecasting, and sends the modified generation scheme to power plants to make the generation sets respond the change of the load more accurately.
Based on identification of sequence boundaries of grade Ⅳ, Ⅴ and Ⅵ and their corresponding lake flood-planes, the 2nd and 3rd members of Yangyi Formation are divided into 9 medium-term, 30 short-term and 64 super-short-term basal level cyclic sequences.
In order to implement object-controllability and ahead control of automatic generation control (AGC), a new method of frequency bias coefficient setting is proposed based on the multi-target optimum technology and super-short-term load forecasting (SSTLF).
Taking account of the characteristics of power load and the applications of AGC units in Zhejiang power grid, a practical design of real-time generation control system based on super-short-term load forecasting is presented.
