On February 25, 2019, at 15:00, Professor Jerry Yan, an academician of the European Academy of Sciences and Arts, was invited to give an academic report entitled "Challenges and Opportunities with Renewable Energy Penetration".  This report was hosted by Prof. Biying Yu, and a number of teachers and students attended the report.

　　Prof. Jerry Yan is an academician of the European Academy of Sciences and Arts and the Dean of the International Institute for Applied Energy Innovation. In 2001, he was employed as a tenured professor in Sweden. He mainly engaged in renewable energy technology and low-carbon technology, energy system integration and optimization, carbon capture and utilization and storage and carbon trade, advanced power generation technology and energy storage, energy efficient use and other aspects of research. He received important awards such as the Global Living Environment Green Technology Award which was supported by the United Nations Environment Development Agency, and finalist of the Global SWFF Award. He has published more than 400 papers in top international journals such as Science and Nature Climate Change.

　　In this report, Prof. Yan focused on the flexibility of Energy systems. One of challenging issues is the mismatching of intermittent power generation and energy supply and demand over a time scale when high renewable energy penetration takes place. This calls for interdisciplinary and synthetic approach from not only the systematic overview, but also detailed components of clean energy systems.  It needs to integrate the end-users load control with different energy saving approaches. It has to be location specified and highly tailored to serve its customers’ needs. Changing from resource conversion into the smart integration also needs integration of energy with digitalization.  Renewables, distributed generation, and smart grids demand new capabilities and are triggering new business opportunities, which is further stimulating the future development of the energy systems. After the report, Prof. Yan took the picture with teachers and students at CEEP together.
