A novel economic optimal control strategy from CITIES / DTU Compute & Krüger A/S suggests that the power consumption in wastewater treatment can be flexible since the water is treated in large tanks with long retention times where specialized aeration equipment is repeatedly switched on and off.

By controlling these switching times with respect to nutrient concentrations, electricity consumption can be predicted and shifted in time and hence provide short-term demand-side flexibility.
The proposed principle is used to reduce the operating costs of a wastewater treatment plant by enabling the flexibility to distribute the aeration load to periods with less expensive power prices.
Highlights:
Significant cost savings for wastewater treatment by shifting power consumption
Favourable to exploit instantaneous price differences in multiple power markets
Optimal energy consumption of wastewater aeration using switching times
Earlier this week, Professor and Centre Leader at DTU Compute Henrik Madsen was awarded with the prize for the best Senior Presentation at the 5th International Conference on Smart Energy Systems in Copenhagen. The presentation ’Perspective in Using Meter Data for Temperature Optimization’ was based on knowledge from the project CITIES, Smart Cities Accelerator, IDASC …
CITIES, University of Zagreb (Faculty of Mechanical Engineering) & The City of Zagreb are organizing a joint workshop on: Data intelligent operation of district heating and district cooling systems In recent years, there has been a growing interest in using big data to improve district heating and district cooling systems. Sensors are becoming cheaper, and …
At a two-day workshop in Zagreb first in April different industry, academia and governmental partners focused on the importance of data-intelligent operation of integrated power and thermal systems for accelerating the green transition using thermal storage solutions on the proper scales. Center for IT-Intelligent Energy Systems (CITIES) project at DTU in Denmark was responsible for …
