| Outline of Final Research Achievements |
In this research, dynamics of an ocean thermal energy conversion (OTEC) plant using hybrid cycle and the control problem were investigated. Here, it is noted that the hybrid cycle has been developed to realize power generation and freshwater production simultaneously. In the model construction to take into the dynamics account, some models with warm and cold seawater flow rates and working fluid flow rate for power generation control were proposed. Furthermore, some control methods for power generation control were also proposed. The effectiveness of the proposed models and control methods were verified through numerical simulations and experiments.
