Research Areas
The main goal of our research is to develop computational methods that ensure cost-effective planning and reliable and efficient operation of the future power grid, with the overall goal to enable a sustainable energy future. This includes the modelling and optimization of the grid across time scales from seconds to hours to years in order to address the challenges of the energy transition. The research focus of the group can be broadly categorized into the following categories.
Dynamics
The group studies the impact of power converters in low-inertia systems, their interactions with conventional machines, and the challenges associated with distributed energy resources. More...
Operation
The group works on developing models and algorithms for optimal control of distributed energy resources and electric loads, leveraging optimization and data-driven methods to enhance grid operation and bridge the gap between research and practical application. More...
Planning
The group's research focuses on decarbonization pathways by modelling electrified energy futures, spanning different scales, from device operations through planning at the national level. More...
Collaborations
PSL regularly participates in research consortia or joint research projects. Such collaborations provide the opportunity to interact with researchers from other institutions and work across domains. Currently, PSL is involved in the following larger research consortia and research projects:
NCCR Automation
The National Centre of Competence in Research «Dependable, ubiquitous automation», NCCR Automation for short, investigates new approaches to the control of complex automated systems and implements them in concrete applications in practice. Through networked research, the development of new technologies and education, the NCCR aims to strengthen Switzerland's leading role in automation and control technology. external page More...
SWEET EDGE
EDGE wants to provide scientific evidence to fast-track the growth of locally sourced decentralized renewable energy in Switzerland. The consortium aims to show that by 2035 and 2050, when ambitious shares of renewable energy are reached, the Swiss energy system could be designed and operated in a technically and economically optimal and secure way, and that it could be well positioned in the European markets. external page More...
SWEET PATHFNDR
PATHFNDR aims to develop and analyze transition pathways for renewable energy integration in Switzerland. The project will deliver feasible pathways, provide planning and operation tools, develop pilot and demonstration projects, identify new business opportunities and innovation strategies, and analyze potential policies. external page More...
Nexus-e
Nexus-e is an interconnected energy system modeling platform which aims to facilitate the energy transition in Switzerland by serving as a modeling infrastructure for researchers, students, and industry partners. Using the Nexus-e platform, we develop pathways for the Swiss energy system and analyze the impact of technological, economic, regulatory, and societal developments. external page More...
OrtsNetz
The increasing deployment of decentralized renewable energy sources and the electrification of the transport and heating sectors place great demands on the distribution grid. To meet these challenges, the OrtsNetz pilot project is investigating the use of time-dependent grid usage tariffs, which are intended to help avoid power peaks in the low-voltage grid and ease the integration of decentralized sources. In this context, the project is investigating and comparing (i) changes in customer behavior through tariff signals, (ii) automated local load control of important consumers (boilers, heat pumps, and electric vehicles) and (iii) direct control of flexible loads by the distribution grid operator based on central optimization.
