Scope and objectives of use case

Scope

Energy systems are traditionally designed so that power energy supply meets demand on a national scale with transnational power grid interconnections and import of oil and gas. The rising share of distributed power and heat generation by renewable energy sources, local storage infrastructure and locally optimized multi-energy systems disrupt this traditional top-down operation and investment thinking.

National scale energy system models, such as the TIMES Belgium linear optimisation model, operate on the assumption that within a defined region (e.g. the respective country) current and future energy demands are met by existing and future service technologies. Optimization happens over a mid-to long term time horizon (e.g. decades) and on a large geographic scale. With energy services being supplied by technologies which are more and more geographically distributed, local optimisation takes on a more prominent role in the energy systems of the future.

For this use case we study the impact of locally-optimized multi-energy infrastructures (generation, storage, distribution and end-users consumption) on the capacity requirements and the operation of national scale infrastructure and technologies. The main question we address is to what extent multi-energy infrastructures can be scaled up to enable a transition to a low carbon energy supply at minimum costs.

Objective(s)

[identify specific objectives]

O1: Analyse the impact of locally-optimised multi-energy systems (generation, storage and consumption) on the larger national energy system infrastructure and operation.

O2: Analyse these impacts for several levels of shares of renewables.
