Biography

Göran Andersson earned his master's degree from Lund University in 1975 in the field of engineering physics. He finished his PhD studies at the same institute in mathematical physics, namely on the theory of rotational excitations in nuclei, in 1980. After his PhD studies, he worked as a research engineer at ASEA, now ABB, in the HVDC division from 1980 to 1985. In 1985, he became the Section Manager for Systems Engineering in the same division until 1986. During these years he was mostly researching on dynamics and control of power systems with a main focus on HVDC. After his time at ASEA, he became a professor at the Royal Institute of Technology at Stockholm. He was the head of the Institute for Electric Power Systems group from 1986 to 2000. His main research focus there was on dynamic stability issues in power systems. He graduated a total of 14 PhD students during his time at KTH, including Prof. Antonio Conejo (Ohio State University). In 2000, he moved to Switzerland where he became a professor at the Swiss Federal Institute of Technology, where he is heading the Power Systems Laboratory.

Göran Andersson is married to Anne since 1975, and they have three children.

Research

His most recent research work can be divided into three major topics within the field of electric power systems:

1. Power System Dynamics and Control: he and his PhD students have studied how VSC-HVDC can be used in the European grid in order to enhance the stability. Other work aimed at investigating the pros and cons of HVDC grids. In this case the European grid was also used as test system. An important aspect considered in this work is the need of communication. As the European system connects a large number of countries, further work within this area focused on the operation of multi-area systems. The interaction between several transmission system operators, each with limited information of the status of neighboring systems, has been studied, and his group has proposed methods aiming at increasing the overall system security through exchange of selected pieces of information. Another important topic that has been covered by multiple PhD theses is the topic of demand response. His group has developed methods and tools to enable thermal loads to offer regulating and balancing power. This has resulted in the spin-off Adaptricity. A key reason why demand response has gained attention is because it can support the integration of variable renewable generation. Prof. Göran Andersson's group has also looked at how in the situation with increased uncertainty, security assessment can be done and formulated as a stochastic program with chance constraints. But the work on security is not just purely focused on the physical aspects, he has also done work on cyber-security of SCADA systems.
2. Power Markets: The aim of the work in this field is to develop realistic models for liberalized power markets, particularly the ones in Europe. An important aspect is the modeling of energy prices, with the aim of forecasting these. The Hourly Price Forward Curve (HPFC) is an important tool in this context, and much work is devoted to this topic. An approach, combining statistical and fundamental models, has been implemented. The original HPFC was usable only for a single price area. His group has been developing it for several areas through the incorporation of market coupling mechanisms. Another application is the valuation of pumped hydro storage plants in the new market conditions. Non-linear learning techniques are used to better capture seasonal variations.
3. Future Energy Systems: Prof. Andersson's group initiated the development the Energy Hub concept around 2003. It is now used by many researchers and planners worldwide. The Energy Hub has been the basis for many projects concerning future energy systems, and the concept has been further developed and adapted for new applications. Additionally, the group has worked in a number of projects regarding the integration of electrical vehicles (EV) in power systems. Together with research groups in mechanical engineering and traffic planning, the researchers at the Power Systems Laboratory have developed a model that incorporates traffic flow simulation and energy consumption while driving, so that the state-of-charge for the individual vehicles can be determined. From this, control schemes for the charging of vehicles taking into account grid constraints, power prices, and the preferences of the vehicle owners have been designed. As another line of research which falls into the topic of future energy systems, the work on developing an expansion plan taking into account corrective control that can be accomplished by HVDC links should be mentioned. It was shown that this possibility could result in substantial savings. Another main contribution of the group concerned operational flexibility, which has gained in interest due to the integration of photovoltaic and wind power, which are fluctuating. A special modeling framework, the Power Node model, was developed for this purpose. The Power Node is related to the Energy Hub and can be seen as a complement.
