General Role: Expert in dynamic thermal system simulations for large scale thermal energy storage and district heating networks and end-user tool tester.
Specific technologies in charge of: Energy system simulation using pytrnsys/TRNSYS.
Main goal of the project: The project’s general objective is to improve the technical design and dimensioning capabilities for the planning of large thermal heat storage systems through the development of a reliable pre-feasibility and design tool for quick assessment based on TRNSYS dynamic simulations.
Extended Summary: The integration analysis of large thermal energy storages (TES) in District Heating Networks (DHN) and renewable sources requires dynamic simulation to consider appropriately the fluctuating behaviour of sources and sinks. The development of dynamic simulation energy models, such as the TES integrated with renewable sources in DHN requires experience, data for its validation, and above all, it is time-consuming. The need to evaluate many possibilities with a little budget in early project stages, such as pre-design, leads planners to use quick methodologies which might lead to inaccurate results and even sometimes delete one technology if a simple evaluating tool is not available. Furthermore, in further project stages, only some advanced planners use dynamic simulations, such as TRNSYS, for the evaluation of TES integrated into the whole thermal system. This project aims to fill this gap by developing a reliable quick assessment tool targeting both pre-feasibility and design phases of large-scale TES, unifying the calculation processes of all project stages in a single methodology. We propose an easy-to-use, user-friendly planning tool based on dynamic simulations models already developed with the TRNSYS-based pytrnsys (https://pytrnsys.readthedocs.io/en/latest/index.html) open-source environment.
