Modelica Sand Heating Package

This open-source Modelica package contains models for particle-based silica-sand thermal energy storage (TES) in heating applications. Silica sand is an abundant, low-cost, and efficient storage medium for concentrated solar power and electricity generation. As an emerging technology, solid particle TES could benefit building and district heating systems, particularly as building electrification and renewable energy penetration increases. To enable heating system design and evaluation with sand TES, this package contains base classes through complete systems with physical equipment, controls, and ready-to-use scripts for simulating and plotting.
