A turnkey solution for Swedish buildings through integrated PV electricity and energy storage (PV-ESS)

Oct 07, 2022

Cities stand out as responsible for a 70% share of global CO2 emissions. There is a high potential for carbon footprint reduction in improving the energy performances of the built environment. Since cities are very dynamic and dense ecosystems, they offer numerous options that can be developed to reach the climate targets. One promising option is the integration of solar PV coupled with energy storage systems (ESS).
The aim on this project is to study the implementation and optimal operation of turnkey solutions involving solar PV coupled to energy storage systems (PV-ESS). For this, a two-fold approach where the impact of policy modifications is investigated by means of techno-economic scenario analyses while also demonstrating key PV-ESS innovations at KTH Live-In Labs.

Integrated modelling and optimization of coupled electricity and heating networks

Oct 07, 2022

The coupling between the electricity and heating networks is increasing due to the integration of co- and poly-generation technologies at the distribution networks. This project aims at modelling, simulating and optimization of multi-energy systems (MES) in general, and coupled heating and electricity networks in particular, with the full consideration of networks' physical and operational parameters. The project lays down the ground for better management of smart electricity grids and smart thermal grids in an integrated way so that district/urban energy systems can be operated in a cost effective, secure and efficient way.

Smart and Robust Electricity Infrastructure for the Future

Oct 07, 2022

The project Smart and Robust Electricity Infrastructure for the Future aims to identify and address future capacity requirements in the Stockholm region as a result of increased electric vehicle use, computerization and heat pump installation. With the help of existing simulation tools at the Institute of Energy Technology, KTH, short and long term scenarios for electricity use are established and the impact on the distribution and production capacity in the region is analyzed. Load flow analysis will be conducted in low and medium voltage distribution networks to identify infrastructure deficiencies. Measures in the form of network upgrades, load balancing and installation of local production will be analyzed and optimized regarding cost and environmental impact. Validation is done with input from Fortum, Svenska Kraftnät and Elbil2020. The methodology should be generally applicable to urban regions in and outside Sweden, and form the basis for decisions on infrastructure investments.
