Join this session of the IEA SHC Solar Academy webinar series by the IEA SHC Task 68 Subtask B on the topic of boosting the efficiency of Solar Thermal District Heating with digitalization, advanced control and open data.
One of the most important applications of solar thermal plants is their use as a heat source for district heating. This way, solar thermal solutions can contribute significantly to a sustainable heat supply – but they also face challenges, both on the single technology level (e.g. efficiently provide suitable feed-in temperatures) and on the system level (handling decentralized feed-in, effective interaction with other heat sources and with auxiliary technologies).
Digitalization offers new possibilities to address these challenges. They allow advanced monitoring of solar thermal plants, including automatic fault detection, evaluation of the performance and predictive maintenance. With a sufficient level of digitalization, advanced control concepts (e.g. model-predictive control, based on mathematical optimization) can be applied, which typically increase the performance of a plant by improving storage use and interaction with other technologies. During all stages of the plant life cycle, from concept and acquisition to planning, to construction and commissioning, to operation and finally, to refurbishment or recycling, a good data basis can speed up the process and make it more efficient. Open data is becoming increasingly relevant for such types of applications.
In this webinar, the speakers will present current market figures and trends in Solar District Heating, results and current activities from IEA SHC Task 68 – Efficient Solar District Heating Systems, specifically from Subtask B: Data preparation & utilization, with a focus on evaluation of performance, advanced control of solar district heating systems and uses of open data for solar thermal systems.
Q/A Session & Recording/Presentations: This 90-minute webinar will include a 30-minute Q/A session and a recording of the webinar as well as the presentations will be available online afterwards. The webinar is organised by the Solar Academy of the IEA Solar Heating and Cooling Programme and hosted by ISES, the International Solar Energy Society.
