In this work, we use a plantwide control framework to systematically identify the control objectives, operational and environmental constraints, and degrees of freedom for a heat to power cycle with a drum, one pressure level and with power as the only valuable product. After controlling the active constraints and the unstable inventories, we are left with the fuel (MV1) as the only degree of freedom with a significant steady-state effect. However, the steam valve (MV2) can be used as a dynamic degree of freedom, to improve the response in transient operation while its steady-state effect is negligible. The result is an unified and systematic perspective on the optimal control operation problems for heat-to-power cycles.

在这项工作中，我们使用全厂范围的控制框架来系统地确定控制目标，操作和环境限制以及带有鼓，一个压力水平和功率作为唯一有价值的产品的热电循环的自由度。在控制了活动约束和不稳定的库存之后，我们将燃料（MV1）留为唯一的具有显着稳态影响的自由度。但是，蒸汽阀（MV2）可以用作动态自由度，以改善瞬态操作中的响应，而其稳态效果可以忽略不计。结果是对热电循环的最佳控制操作问题有一个统一而系统的观点。
