Background of model application
To achieve its climate protection targets, the German federal government has declared to transform its energy system. Therefore, a fundamental restructuring of the energy system as we know it today is necessary.
How can a cost-optimised transformation of a national energy system – with consideration of all energy carriers and consumer sectors – be achieved in line with meeting the declared climate targets and ensuring a secure energy supply at all times? By running customized scenario-based simulations the REMod model is most suitable to answer specific questions concerning the transformation of a national energy system. In repeated cooperation with federal and state ministries, international research institutions and above all through the close exchange with industrial customers, the applicability as a strategic consulting tool was proven and the model is continuously further developed.
Characteristics of the model
The basic functionality of the REMod model is based on a cost-based (non-linear) optimisation of a national energy supply system, whose energy-related CO2 emissions do not exceed a specified target value and/or target pathway. The optimisation target is to dimension all generators, stores, converters, and consumers at minimum costs such that the energy balance of the overall system is met in every hour from today to 2050. Each technological property can be displayed in any level of detail. For example, different charging strategies for battery-electric vehicles or the interaction of thermal storage and different heating systems can be modelled as realistically as possible. In addition to ecological sustainability and cost-effectiveness, the model also takes account of security of supply through a high level of technical detail and temporal resolution, which reconciles energy supply and demand at all times throughout the year.
