WP03
Technologies, design, and operation of thermal grids for future energy planning
Abstract:
Thermal grids are essential for the energy transition of the Swiss building stock. In this work package, we determine boundary conditions and optimal ways of integrating renewables and storages in thermal grids. We deduce grid design concepts that optimally exploit all available temperature levels for both, heating, and cooling. Robust control algorithms will be developed and tested in dynamic simulations as well as experiments. System costs will be estimated. The findings will be condensed and simplified in tools and guidelines for local energy planning and for inclusion in WP01 and WP06.
Objectives:
Thermal grids allow to distribute renewable energy and to recycle waste heat from cooling for heating. WP03 develops technical solutions for future thermal grids and grid-connected applications like thermal storages. It further develops a solid understanding of new thermal grid concepts and its underlying control algorithms to form a base for future energy planning.
