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
Sænkning af fremløbstemperaturen med 10 grader, markant reducering af varmetab samt fastholdelse af varmeprisen. Svebølle-Viskinge Fjernvarmeselskab udnytter de digitale muligheder. I magasinet Dansk Fjernvarme kan du læse mere om gevinsterne ved datadreven styring og visualisering i Svebølle-Viskinge Fjernvarmeselskab (m bl.a. Svend Müller). Her samarbejder DTU – Technical University of Denmark (m Henrik Madsen, Per Sieverts …
Research projects have created coherence between the surplus production of wind energy especially at night and the local electricity consumption in 30 holiday homes with indoor pools in Blokhus and Blåvand at Vestkysten. The perspective is enormous, and therefore the partners continue under the project Center Denmark. Professor Henrik Madsen participates on Friday at 4:30 …
These weeks, Hong Kong is massive in the media due to major demonstrations and unrest in the city, but life in the city continues alongside. Last week, PhD student Hjørdis Amanda Schlüter and Professor John Bagterp, both affiliated with CITIES and the Smart Cities Accelerator at DTU Compute, attended the IEEE CCTA 2019 (Conference on …
