Short description

The test case is used to calculate the system costs of the Collectopia Reference Energy Systems (RES) to find out if seasonal storage is economically feasible considering CO2 savings.

Present use / development status

Test objective

characterization

Description incl. justification

This test case aims to find the cost-optimum technology mix for the Collectopia RES and to find out if seasonal storage is economic favourable. Therefore, a RES is set up with all technologies that are potentially of interest, including seasonal storage of heat. Based on this, the cost-minimal configuration can be determined.

System configuration

Collectopia RES (see deliverable D2-3, Appendix E)

Use case

System Under Test

The RES consists of energy production technologies, e.g., PV, HPs and gas CHPs, imports and exports to external grids as well as the aggregated electricity and heat demand depending on numbers and types of buildings. For the Collectopia case, battery storage and biogas production are excluded, and for the heat storage a hot water tank is considered, see Figure D.1.

Object Under Investigation

capacity costs of the entire system technologies

Function Under Investigation

net total discounted system expenditures (to be minimized)

Objective Function / Target Metrics

Discounted cumulated system costs (see deliverable D4.2, Appendix D.2, page 42).
