Development of an Operation Assitance System for the Solar Power Plant in Juelich

 

Motivation

Solar power plants are inevitably operated dynamically due to the strongly fluctuating influencing variables, such as solar radiation, etc. Consequently, even the most experienced power plant operators face major challenges with regard to the question how, under current operating conditions, the power plant can be operated efficiently. In order to support the power plant operator in this question, an operating assistance system is to be developed, which makes proposals for an optimal driving system with regard to different target variables (efficiency, etc.).

 

Method

The operating assistance system is based on a dynamic simulation model of the total power plant. By employing this model, simulations of the power plants future state are carried out, taking into account current conditions. Optimization algorithms use the data from the simulations and find optimal driving strategies, which are made available to the power plant driver based on the target variables. Within the scope of the work package the IKDG is responsible for the creation of the dynamic model of the water / steam cycle.

 

Funding

The project is realized as part of work package III within the framework of the "SiBops" - "Simulation-assisted optimization of operation for solar power plants" project and funded by ETN, the Research Center Jülich, over a period of 3.5 years.
