Embodiment Construction
[0023] It will be observed that in the figures, method steps and system components have been represented by conventional symbols, only specific details being shown that are significant to an understanding of the present disclosure. In addition, details that can be easily understood by those skilled in the art may not be disclosed.
[0024] Exemplary embodiments of the present disclosure provide methods and systems for dispatching power plant loads.
[0025] Normally, power plants are dispatched to generate electricity over time periods / forecast time domains that vary from days to weeks, known as short-term load dispatch. Plant production scheduling based on power / steam demand, availability of plant components, and net revenue from production. As stated, the optimizer uses different cost factors including penalties for not meeting demand, revenue from electricity sales, fuel consumption, emission reductions, component depreciation, startup and shutdown of components to optimal...

The present invention relates to a method for optimizing load scheduling for a power plant having one or more generation units. The method comprises the steps of analyzing the operating state of one or more components of generation units in terms of one or more risk indices associated with one or more components of generation units; updating the objective function that reflects the state of one ormore components of generation units; solving the objective function to optimize schedule of the one or more generation units and operating state of one or more components of generation units; and operating the one or more generation units at optimized schedule and operating state. The invention also relate to a control system for scheduling load of a power plant having one or more generation units. The control system comprises an optimizer having a single objective function for optimizing load scheduling which includes maintenance scheduling and for optimally controlling processes of the oneor more generation units. The optimizer utilizes a plant model component and a failure model component for load scheduling optimization.
Description
technical field [0001] The present disclosure relates to the field of dispatching in power plants. More specifically, the present disclosure relates to dispatching loads of power plants. Background technique [0002] Optimization is the technique of controlling a process so that a specified set of parameters is optimized without violating the constraints of the process. Conventionally, optimization processes in power plants are performed to increase efficiency, reduce potential emissions, reduce costs, and maximize system availability for power generation. There are multiple systems in a power plant that can be optimized independently for better performance, for example upgrading a particular component of equipment in a power plant can result in less fuel consumption. Also, the overall operation of the plant may be optimized by optimizing one or more factors that contribute to the overall efficiency of the plant. [0003] In general, it is desirable to optimize load sched...
