Talk Title
What does an optimal future energy system require? A perspective on modelling and policy requirement in energy transition

Talk Abstract

Clean energy supply necessitates energy production systems that rely on a mix of renewable and energy storage technologies. The past decade has seen a gradual but important shift towards adopting these new sources. As time passes, transitioning to these new technologies will definitely bring new technical, market and policy questions. This is because of the underlying difference in technical characteristics and the utilization of these technologies from that of conventional generators. One of the key questions of interest relates to design and operation of the future system. Several modelling activities have been performed throughout the globe using different modelling tools. As a result, it is difficult to see a unifying theoretical framework regarding energy transition. However, it is clear that an increased penetration of variable renewable depends on curtailment and energy storage technologies. Past and ongoing research shows that storage, curtailment and penetration should simultaneously increase in certain fashion during energy transitions. This resulted because of the physical relationship between these three parameters. To measure this relationship, modelling should conform to certain requirements. At the same time, new policy measures and principles may be necessary to provide effective solutions to our energy challenges. In this presentation, we will revise current modelling efforts in the areas of energy transitions and present a theoretical framework that will give a key modelling principle to be satisfied for an effective system design and transition. 

Short Biography

Solomon Abebe Asfaw, PhD, received his undergraduate degree in Physics from Bahir Dar University, Ethiopia; M.Sc. in Physics from Norwegian University of Science and Technology, Norway; and another M.Sc. and a PhD, both in energy system modeling from Ben-Gurion University of the Negev, Israel. He was a recipient of the 2010 Wolf foundation prize for outstanding PhD students in Israeli Universities. He was a postdoctoral researcher at the University of California-Berkeley, supported by a fellowship grant from Philomathia foundation. Then, he moved to Addis Ababa University (AAU), where he worked as an Assistant Professor of Energy Systems and the head Center of Energy Technology. Currently, he is a senior research fellow at Lappeenranta University of Technology, Finland.  His research interest is in the area of energy transition and the question of power system planning and optimization, particularly in addressing the challenge of variable renewable energy (VRE) integration and energy storage. His findings, which covers various aspect of future power system design,- including power system dispatch, least cost generation and transmission planning, issues of storage design, etcetra,-  as well as different regions of the worlds, are published(in a process) in various journals and as a part of books.
