Project abstract

Over the last decade, the prerequisites of the electric power system have changed remarkably. Nowadays, consumers are interacting with the power grid to a much larger extent than expected when designing the system. The integration of distributed solar energy production and charging of electric vehicles are only two among several more new upcoming consumer interactions. Besides, the technological development also points towards an increased electrification of the society. This will result in a higher electricity demand and larger daily fluctuations. At the same time, a transition from centralized to decentralized power production is taking place as of the integration of renewable energy sources. This also brings intermittency to the power system, thus the task to maintain balance and high power quality in the power system gets even more challenging.

This project aims at investigating the changes in current distribution grids as of the described challenges. Additionally, it is of importance to consider the energy storage aspect to claim and verify what role different energy storage techniques can and will play in future electric energy systems. One interesting approach is to consider a hybrid energy storage with multi-objective functionality, i.e. using a setup with more than one storage technique to accomplish several services simultaneously over one or more time scales.
