The problem facing the United Sates electric power industry today can be attributed to society’s ever increasing demand for energy, environmental concerns with reliance on fossil fuels, and uncertainty about an aging infrastructure’s ability to cope with increasing demand for energy. Existing control systems for power plants are rigid and lack the capability to provide optimal operation with increasing amounts of requirements placed on the power plants, prompting the need for a more adaptive, robust control system. The object of this thesis aims to develop and present an optimized control system based on the concept of Multi-Agent Systems (MASs), which have been applied to other complex problems in the power industry. This thesis applies a MAS distributed control methodology to a large-scale power plant optimized control system, improving the overall flexibility, autonomy, and robustness of the control system, which in turn increases the efficiency and operation of the power plant.
