dc.description.abstract | We use a systematic plantwide control framework to analyze optimal operation of a simple heatto- power steam cycle with a single pressure level and a drum. The present control solutions for power plants1 have been developed to a level where it difficult to make significant performance improvements using more advanced and systematic control policies, such as model predictive control, unless one has a clear definition of the overall control problem. Hence, the objective of this work is to make a first step in the direction of systematically defining the optimal operation and control problem for power plants. We analyze two typical operation modes of the plant: 1) maximizing the cycle efficiency with given plant load, and 2) maximizing the production (power output) with given heat input. We determine that after fulfilling controlling the constraints there are two unconstrained degrees of freedom left that can be used to achieve optimal operation | nb_NO |
