Deliverable 5.3 provides information about the adaptation of the IPSE GO Web-Platform for RESTORE dynamic and techno-economic modelling to represent the six different Use-Cases defined in the project. Deliverable D5.3 is the result of the work carried out in task T5.3 led by SIMTECH, during the period of month M1 to M40 of the project. The main purpose of this report is to describe the development needed to adapt the simulation platform IPSE GO for using the steady-state IPSEpro process models to properly present the results for the RESTORE transient models via a web browser. Hence, D5.3 describes the implementation performed by SIMTECH in the web-platform to support dynamic modelling, as well as the evaluation of main economic parameters to make the techno-economic analysis of theRESTORE project possible in IPSE GO. The information provided in this document builds upon collaboration between SIMTECH, CENER, TU-WIEN, and POLIMI, as RESTORE partners involved in task T5.3. Task T5.3 receives input from WP5 tasks T5.1, T5.2 and from WP1-T1.4 relative to the specification of the Use-Cases for simulation. In this sense, besides D5.3’s central scope on the adaptation of the IPSE GO Web-Platform for RESTORE dynamic and techno-economic modelling, using SIMTECH’s simulation tools, it also considered the outcomes published so far in the deliverables of WP1, WP2, WP3 and WP5.
