The "optimization-cycle" start with the data acquisition and analysis. In this stage, all input data is prepared for the further steps and a systematic evaluation is performed.
Based on the data analyis, operational strategies will be developed in the next step. The purpose of these strategies is to calculate and provide setpoints for the components, while taking into account various optimization goals. There are two different levels of strategies:
- Plant level: local operational strategies which ensure the reliable operation of the plants (including storage, if applicable) and provide an interface to energy management.
- Energy management level: overall control and optimization of the entire energy system.
In the step simulation and optimization, a digital twin of the energy system is developed. The model is used for scenario-based investigations (e.g., energy supply scenarios) and for optimal dimensioning of the components. Note the feedback to the operating strategies: these are also consolidated with the help of the digital twin and adapted as necessary.
The last step, the implementation phase, involves developing the automation functions and implementing them in the real system. Here, too, there is feedback: on the one hand, back to the simulation, and on the other, back to the start, true to the motto “after optimization is before optimization.”
