Integration of stochastic renewables in the Swiss electricity supply system (ISCHESS)

The project studies the impacts of adding distributed stochastic generation to the Swiss electricity system is divided in 2 phases. The first phase focuses on evaluating the impact of RES (mainly photovoltaic generation) at the distribution voltage level, while the second phase extends the study to the Swiss national scale and thus also consider the higher voltage levels of the transmission grid, along with a wider range of RES and additional storage options. PSI’s Technology Assessment group is involved in a number of work packages and tasks, namely (1) definition of objectives, indicators and scenarios, (2) technology assessment including Life Cycle Assessment, (3) assessment of alternative RES integration strategies, and (4) energy system modeling.
