深度调峰下控制系统策略优化

摘要：在当前“双碳”背景下，各区域电网对火电机组深度调峰能力要求逐

步增加，如华北电网要求火电机组深调能力达到20%额定负荷。并在“两个细则”

中AGC及一次调频对火电机组考核的基础上，各区域电网纷纷制定了《并网发电

机组深度调峰技术规范》专门对火电机组深度调峰下的AGC及一次调频的考核指

标要求进行说明，逐步完善对火电机组深度调峰下的考核体系。随着深调的常态

化，具备深调能力的机组逐步增加，《并网发电机组深度调峰技术规范》的逐步

完善，针对深调机组，也会加大AGC及一次调频考核力度。若发电企业无法在50%

负荷以下投入AGC，则会增加发电企业受电网的考核，影响机组深调运行的经济

性。
