Scope and objectives of use case

Scope and objectives of use case


The energy challenges have become topics of increased attention and debates in the society: decline of fossil resources, rise of awareness regarding the environmental impact and demand for improved security of supply. The supply of energy from local resources is a promising element of response to the issues at stake. Amongst others, the energy harvesting and distribution at district scale (in particular from renewable and waste) could lower the CO2-eq impact and the losses in the networks.


This use case studies the potential of local energy supply with a centralized management of the distributed energy resources and the scattered energy infrastructures (power-to-heat, storage). Such an interconnected system enables synergies and optimal conversion between energy carriers (electrical and thermal). Consumers in the district have independent profiles of energy demand to be met. Pooling the uses enhances the exchanges and the collective energy balances, thus potentially increasing the share of the energy supply locally produced. The objective is to work towards a local energy network more self-sufficient.


The system under discussion includes: the local (renewable and waste) energy resources, the exogenous energy resources (always available), the equipments for energy conversion and energy storage, and the networks for energy distribution. The use case studies the articulation of the system’s elements but does not focus on the ICT domain (centralized device for energy management, control panel and user interface to operators, control signals etc.).


[identify specific objectives]

O1: Maximize the energy supply from local resources (renewable and waste) with a centralized use and management of the energy infrastructures.

Narrative of use case

Narrative of use case

Short description


The local consumers have their own independent profiles of energy demand (electrical, heating and cooling). The centralized energy operator orients the energy flows from the different energy resources and through the equipments to meet the demands. All resources and equipments are controlled as a whole to optimize the collective energy management.


Complete description

[More verbose description; include for example details about control domain, requirements towards input signals or applicable system operating modes (normal, emergency, …) ]

  • The demand profiles should be met within a band of acceptable energy gap.
  • The management of the equipments have to comply with the technical constraints (maximum number of on/off cycles, minimum load etc.)
  • The economics of the systems will be investigated


Optimality Criteria

(Directly associated with objectives. E.g. by what metric to 'minimise' something)

Optimality Criteria




Reference to mentioned use case objectives


Energy met

Minimize magnitude and duration of deviation between energy demand and energy distributed



Primary Energy Efficiency

Achieve objectives with minimal primary energy use



Economical optimum

Minimize costs


Use case conditions

Use case conditions


[Assumption; assumed relation to other systems: e.g.  higher level controller sends a signal]

  • All the elements of the system (eg. heat exchangers, pumps, boilers etc.) can be operated with the decisions coming from a centralized center
  • The system and consumers are treated as one entity (as opposed to for ex. agent-based modelling appproaches)



[Triggering Event (update of control signal or disturbance ...)]
