Improvement on the AGC Zoning Control Strategy in the Interconnected Power System

提出一种AGC分区控制策略。通过减少分区数和判断条件的设计,使AGC分区过程更简捷、合理。通过PID参数的同时调整使得AGC的动态和稳态性能都得到改善。仿真试验结果表明:新的AGC分区控制策略提高了CPS指标,又降低了频率偏差。

An AGC （automatic generation control） zoning control strategy is put forward. The AGC zoning process becomes more simple and reasonable by reducing the number of partitions and judgment conditions. The dynamic and stable performance of the AGC process is improved by adjusting PID parameters simultaneously. Simulation test results show that the new AGC zoning control strategy can make the CPS （control performance standard） performance better and frequency deviation lower.
