Embodiments of the disclosure provide a method for operating a combined cycle power plant (CCPP) (12). The method may include creating a variant control profile for the CCPP (12) for a power plant model (68) of the CCPP (12). The method may include modifying the variant control profile in response to the variant control profile not reducing the fuel consumption or meeting the quality threshold (228). The method may also include adjusting the CCPP (12) to use the variant control profile in response to the variant control profile reducing the fuel consumption and meeting the quality threshold (228). Using the variant control profile adjusts a turbine section inlet temperature schedule or an exhaust temperature schedule for the CCPP (12). 本公开的实施方案提供了一种用于操作联合循环发电厂(CCPP)(12)的方法。该方法可包括为CCPP(12)的发电厂模型(68)创建CCPP(12)的变体控制特征图。该方法可包括响应于变体控制特征图不减少燃料消耗或不满足质量阈值(228)而修改变体控制特征图。该方法可还包括响应于变体控制特征图减少燃料消耗并满足质量阈值(228)而调整CCPP(12)以使用变体控制特征图。使用变体控制特征图调整CCPP(12)的涡轮节段入口温度计划表或排气温度计划表。
