4.1. Energy system analysis methodology and assumptions
The technical and socioeconomic study has been conducted on the basis of the same assumptions as the previous study described in the following. More information on a number of specific details can be found in Refs. [34,35].
The calculation of consequences for fuel consumption and electricity exchange in the national Danish energy system as well as the analysis and design of suitable investments in different combinations of district heating production units have been carried out in the energy system analysis tool, Energy PLAN, using a model of the complete national Danish energy system. This tool, which has been developed at Aalborg University, can be freely accessed from the website www.energyplan.eu. On the same website, one can find links to documentation, journal papers and a training programme. Fig. 1 shows an overview of the model.
Energy PLAN is described and compared to other models in Ref. [36]. The main purpose of the model is to assist the design of national or regional energy planning strategies, encompassing the whole energy system including heat and electricity supplies as well as the transport and industrial sectors. The model is a deterministic
